When the drainage infrastructure fails it could spell disaster for your home or neighborhood. Council lines are not immune to failure, especially during a storm surge. When this happens it can cause flooding. Putting your home at risk of water damage. Even something minor like a boggy lawn can lead to problems in the future. Furthermore, If your home is older than 30 years old then this could put your home’s foundation at risk, causing structural faults.
So, flooding can be a serious issue for your property. Therefore having sufficient drainage solutions is key to prevent unexpected damages. Saving you a headache and thousands of dollars in the future.
If you notice parts of your property, such as your lawn collecting water this may be a sign of poor drainage. Subsoil drainage can help solve this issue. A pipe is placed underground and removes excess water to a nearby storm water sewer.
But what if the Council Lines Fail?
The drains and sewers built by the local council to serve as drainage for your area are only rated to a certain capacity. If there is a significant amount of rain such as during a storm then this could lead to flooding. Rivers could begin to spill out of their banks, and debris could clog the pipes. When this happens the council lines may not be able to remove the water fast enough.
If your area is prone to floods and you are concerned for your property what actions can you take to protect your home? Since subsoil drainage relies on the council storm water sewer then it is as good as useless in the event of flood. However there is a solution.
Underground detention tanks act as a buffer between your home’s subsoil drainage and the council lines. A detention tank stores water and discharges it into the council lines slowly to prevent over burdening the system. This also means that in the event of a storm, the tank can simply store the water until the drain can remove it.
If your property suffers from flooding or poor drainage give us a call at 0800 DRAINLAYER (372 465) or contact us online for a solution.
Drainage NZ is proud to announce that we are now an approved drainage contractor for Veolia. This certificate allows Drainage NZ to provide its wastewater services to the Papakura district public assets. Drainage NZ brings over 20 years of drainlaying and wastewater expertise to the community of Papakura, providing competitive pricing without compromising quality.
What is Veolia?
Since 1997 Veolia has maintained and operated the water and wastewater infrastructure of the Papakura District. Papakura, Takanini, Drury, and the Hingaia Peninsula all rely on the Veolia for essential lifeline services. Typically, water and wastewater services in Auckland are managed by Watercare. However, the task of providing water and wastewater services for more than 1.7 million Kiwis proved to be too daunting. So, in 1997, Watercare awarded a first of its kind contract to Veolia to become, at the time, the only private sector water and wastewater provider in New Zealand. Picked for their focus on sustainability and high standards, Veolia brought their international expertise to New Zealand to effectively manage the water and waste of thousands of kiwi homes.
Who are we?
Drainage NZ has been a name in the drainage game for the past 20 years. Our expertise and experience have awarded us membership to the Master Drainlayers, as well as certifications from Watercare, Auckland City, and Manukau City. Our exceptional team of qualified drainlayer’s has gained the trust of millions of Kiwis, making us a preferred provider for all commercial, residential and public drainage services.
What commercial, residential & public services do we provide to Auckland?
Drainage NZ takes a diligent approach to every job, no
matter the size. We always locate all existing services before undertaking any
drainage or drilling work. We locate and mark existing power, gas, water,
drainage, telecom, and power lines to ensure a safe and non-destructive job.
Drainlaying in New Zealand is a licenced industry requiring
drainlayers to be qualified and registered to provide services. Furthermore,
Auckland requires drainlayers to hold additional certifications for any work on
public wastewater systems. Drainage NZ holds a range of certificates from
several New Zealand and Auckland drainlaying authorities, including:
– Auckland City registered.
– Manukau City
These certifications mean Drainage NZ is qualified and
trusted to perform any job on public wastewater systems in the greater Auckland
area, except for Papakura, for which Drainage NZ has lacked proper
certification… until now. Adding to our list, Drainage NZ has become Veolia
approved. This means Drainage NZ can now provide its master class services to
the entire greater Auckland region.
How do you get approved by Veolia?
To gain approval from Veolia a drainlaying company must provide sufficient evidence demonstrating relevant skills, experience, and knowledge of drainlaying and wastewater systems. With 20 years of experience and practice in the industry, and years of experience working under Watercare NZ, the application process was quick and stress-free. In 2021, after analysing our previous wastewater work, and confirming our registration as drainlayers, Veolia approved Drainage NZ to work on Papakura public wastewater services.
Examples of what services we can now provide:
Not all drainage services require approval from local water
and wastewater providers, however more complex work such as wastewater services
do require certification. Veolia is the provider of wastewater services to
Papakura and a few surrounding regions, meaning, Drainage NZ is now able to
provide wastewater services to more Kiwis than ever.
Services we can now provide to the Papakura area:
– Council and
Public drainage connections and installations
– Design and
Any drainlaying service requiring interaction with existing public wastewater infrastructure in Papakura can now be undertaken by Drainage NZ. Drainage NZ has provided these services to Auckland for years, but now with Veolia approval, we can extend our wastewater services to Papakura.
An example of a future project now possible in Papakura is a new manhole installation. Most manhole work is considered public work, requiring correct certification. Installing a new manhole involves connecting to an existing wastewater pipeline. These pipes are managed by Veolia in Papakura, so only Veolia-approved service providers are legally able to make these connections.
Drainage NZ is proud to be able to now provide all of our services to the entirety of the greater Auckland area. Partnership with Veolia means taking on board its commitment to the community and taking responsibility for providing honest quality services to the people of Papakura.
Our technicians are eager to get to work. If you are in Papakura looking for competitively priced wastewater services, Drainage NZ is happy to provide you with an expert quality service enjoyed by Auckland for the last 20 years. For inquiries or a quote call us at 0800 372 465 or contact us here.
Thanks to our team of expert drain unblockers in Remuera, we were able to clear the line so that the occupants can use everything! when it comes to a block like this, as it is very uncommon for a line to block this intensively without there being something to cause it, we recommended our drain unblocking and CCTV combo deal. We put the camera down the line to investigate what could have caused the blockage, what we found was a number of cracked sections, with tree roots coming is, as well as a completely collapsed buchan trap, but even then we still got the line free-flowing so that it can be used before the appropriate repairs are completed which were quoted the same day.
Going down to the basement and finding that it’s filled with nasty moulds can be quite a nightmarish situation. Besides the fact that water damage is quite an eyesore, those rapidly growing microscopic organisms can trigger several health problems and structural concerns. Fortunately, there are ways you can prevent or mitigate mould damage in basements. Read through our short guide below and get expert insights on how you can handle the situation.
What are Moulds, and How can they Affect you?
Moulds can grow anywhere, even in well-maintained places. It’s a type of fungi, which means it propagates quickly in highly moist areas. The humid climate in New Zealand is also a major contributing factor of mould overgrowth.
They naturally occur outdoors, especially on dead trees and other types of debris. However, they can spread on various material such as wallpaper, wooden tiles, ceiling, and wooden supporting beams when they invade homes. If left undiscovered, mould overgrowth can cause severe structural damage as the materials rot and weaken. It also impacts your home’s aesthetic because of dark or sometimes greenish stains on the affected areas.
As we’ve mentioned earlier, moulds can also increase risks for many health problems, including:
How to Prevent Moulds from Growing, especially in the Basement
Most of the time, mould problem starts in the basement due to leaky pipes and other plumbing issues. That’s why it’s crucial to have your pipe problems fixed before they cause water damage. Some signs of pipe damage or leaks that you need to look out for include the following:
Unexplainably high water bill
Musty smell especially in rooms with a lot paper and wood
Visible stains caused by mildews or moulds
Wet and moist parts on the ceiling or walls
It’s also good practice to check for basement flooding. If your property was constructed back in the 1980s, it might be susceptible to basement flooding due to the absence of subsoil drainage. While it may be tempting to use stormwater sumps, it’s best to choose either waterproofing solutions orsubsoil drainage installation to keep the water from coming in and accumulating in the area.
Here are other specific applications of subsoil drainage installation:
Properties with uneven landscape and high contour differences
Auckland homes that have clay soil
Properties that require building retaining walls
If you already have subsoil drainage, you may opt to use basement flooding solutions instead. Talk to a drainlayer to know the most practical method to use to waterproof your home.
What to Do after Getting Rid of Extra Moisture in the Basement
Once you keep the moisture levels at an ideal rate, it will be easier to prevent or mitigate the damage. If you’re only dealing with minor damage, scrubbing with a powerful cleaning solution made from soap, bleach and water may be enough to clear out the mould and mildew.
However, if the damage is too severe and extensive, it’s better to call for a mould remediation professional. Dealing with severe mould overgrowth in your home is not recommended because it exposes you to health risks. Also, you might not address the problem as effectively as a mould removal or remediation specialist would.
Take note tht failing to remove or clean all the mould-infested areas would only spell trouble for your hour household in the next few months. The moulds can grow back and cause the same problem over and over until you completely address the root cause of it all.
Act Fast and Prevent Future Problems!
If you think your area is susceptible to mould damage and infestation, you need to act quickly. Have your drainage checked or ask for a professional house waterproofing to prevent moisture from seeping into the interiors. It’s also helpful to eliminate other moisture sources in the property such as washing machine or dishwasher leaks, poorly insulated windows or crawlspaces, and sewer backups.
Get in touch with a drainage specialist or anAuckland drainlayer today to help protect your home from moulds.
In New Zealand a common method of managing rain water is Soak Holes. In the following information we will be focusing on the city of Auckland which is the most populated and quickest growing region in New Zealand.
In Auckland managing rain or so called “Stormwater” correctly is critical for the cities growth and infrastructure. Auckland Council is constantly challenged by the ever changing weather patterns and population growth. As the population grows so must the public stormwater system, the problem councils have is that the population is:
Outgrowing the public stormwater system
The public Stormwater system can’t grow quick enough to keep up with the demand. This is a costly task that only can only be done during certain times of the year and only as it’s needed. As such, councils are always behind on growing the city’s public infrastructure.
Several years ago, council engineers came up with a quick fix that would help slow down the effects of population growth and the introduction of more water being collected from new roofs that would discharge into the public system.
Design regulations for new builds and subdivisions now included the requirement and/or option to;
Allow a property to manage its own stormwater as much as much possibly practical by means of retention tanks, detention tanks (regulated overflow allowing the public system to keep up when there is a high demand) and soak holes.
In section, we will be focusing on the different types of soak holes and how they can help property owners manage rain water from roofs and surfaces successfully.
Three Different Types of Soak Holes in Auckland
Residential Soak holes
In the early days many areas around Auckland did not have a public storm water system to connect onto. If you had a public connection, you were considered very lucky! Year later in 2020, some areas still don’t offer public a infrastructure. Many homes, especially those built in the 60’s and 70’s continue to manage their roof and surface water within the boundary. This is typically done by means of an onsite ‘Soakhole”.
As drainlayers when we ask for a LIM to identify what
Its all about ground percolation and enabling a site or home to manage its own roof and/or surface water within the site itself. What better way is there than allowing nature to do its own thing? The concept of the Onehunga soakhole does exactly that. (Speak to Drainage NZ about Soakhole drilling, engineering and design.
A GEOTECH drilling rig is arrange to drill down into the volcanic bedrock where a pipe riser is inserted to enable water to overflow as far down as applicable design stipulates. At that point, water will disburse naturally underground. Geotechnical drilling services are available)
As you can see in the design below, the soakhole does have a safety mechanism in case the drilled bedrock hole blocks or should the incoming water exceed the soakhole capacity. This is the overflow point shown as the entry head.
At this point water may overflow into the public system or external soakage trench as shown below.
Trench Field Soakholes
When rock is not available the GEOtechnical engineer may explore the option to discharge stormwater into a scoria layer underground if the site is suitable. The principal is simple. If found scoria layers can act as a disbursement field by allowing water to travel downstream across a whole suburb below the ground, naturally finding a route to the ocean. Because percolation is limited.

The purpose of this Manual is to provide guidance in the design of stormwater soakage devices for residential and commercial properties in soakage areas of Auckland City. Soakage areas have limited stormwater reticulation, and are primarily located in parts of Ellerslie, Penrose, Onehunga, Mt Eden, Epsom, Mt Roskill and Mt Albert. Public soakage devices are provided for runoff from roadways in these areas, but individual property owners must construct and maintain their own soakage devices for runoff from private properties. The soakage devices allow stormwater to percolate into the ground, and generally consist of either boreholes into fractured rock or large holes filled with scoria.
Can I make my own Soakhole?
The building code does allow a certain extent of “Garden Drainage” without involving a specialist, designer or even a registered drainlayer. We highly recommend you familiarise yourself with the rules before you attempt a DIY. Getting wrong could cause severe your or others property.
The quick answer to the question above is no. Soakhole need to be designed based on a series of things, including:
Location (certain criteria needs to be met)
Incoming water capacity
Size and depth
The law is a more flexible around existing soakholes that need repair or redrilling. A repair may bypass all the consent and engineering requirements.
If you need your soakhole repaired, moved or removed please speak to our drainage engineers that will be able to help you find a solution that suits your budget and site.
Not only should clients be aware of what the engineering notes are but so should the contractor to ensure a realistic scope is covered which will allow the client to budget the project accordingly.

Working on a property development or construction project sometimes entails installation, modification and extension of public drainage systems. As a result, you may be required to apply for a Works Over approval. Typically, before proceeding with the project an engineer or Watercare representative will get involved to ensure compliance is met and to ensure that the process won’t put the Watercare assets at risk of getting damaged.
As a drainlayer, we help you ensure that the condition of any public sewer system is investigated before or after any work takes place. The inspection procedure is carried out with CCTV equipment and still images.
Watercare Asset CCTV Inspection
Before Watercare Asset CCTV Pre and Post Inspections became popular, plumbers had to do open-cut excavations. While sewer excavations can deliver results, it can be a very intrusive process. It also consumes a lot of time and costs a lot of money. Unless you are 100 percent sure that the pipe damage is severe, you don’t need to opt for a sewer excavation service.
A CCTV drainage survey is more than enough to help you find the root cause of your drain pipe problems in a residential or commercial property. It’s also the fastest, most practical and cost-effective way to inspect Watercare assets.
How does CCTV Pipes Inspection work?
The process involves inserting a sophisticated camera to inspect the pipes. For larger pipes, like those used in sewerage systems, a CCTV tractor is used. For smaller ones, such as those used in Watercare assets, plumbers utilise a snake profile camera.
As the plumber pushes in the camera inside the pipes, you get to check for possible problems such as clogs, cracks and leaks. You can either have the option to check the video feed in real-time or review it after the service with the DVD provided by the plumbing company.
Typically, the video contains overlaid text containing details like the pipe name, street address, pipe diameter, pipe shape, date and time of CCTV inspection and depth of the access points.
After the survey is done, the plumber will discuss the findings. Below are some of the key things that you can check via a CCTV pipe inspection:
Hairline cracks that affect the integrity and stability of the pipes
Bigger cracks that can affect water pressure and bring in sand and silt inside the pipes
Tree roots and other organic debris stuck inside the pipes
Punctures on the pipe due to previous renovation work
Corroded or severely damaged pipes and assembly joints
Location of other pipe joints and how to access them
Pests such as cockroaches and rats that poses risk for pipe damage and health issues
Timely or regular inspection of drain pipes through CCTV surveying can help you save a lot of money on repairs or other services. It can also help you find out what plumbing issues you need to address before proceeding with a construction, development, or renovation project. If in case the sewerage pipes in the property need work because of material buildup, you can avail a combo package which includes CCTV pre and post-inspection service and drain unblocking.
Beyond Pipe Repairs and Damage Mitigation
Besides coming handy in finding plumbing issues to fix in a property you already own, a CCTV drain survey can also be useful in other scenarios. For example, before you purchase a new property, you can have the pipes inspected to check for pipe problems.
It will help you determine whether it makes sense to invest money in a certain property. Knowing potential or existing drain pipe issues would also allow you to renegotiate the price so you can make room for your renovation expenses.
A typical CCTV survey would only cost you hundreds of dollars per hour. It’s a good investment whether you’re a property owner or a property developer.
The Drain Pipes are Damaged or Clogged, What’s Next?
If the CCTV survey indeed reveals that your pipes are damaged or clogged, your next priority is to plan your next step. You can figure out the approach to use, depending on the severity of the problem. For example, if the results show hairline cracks, you might need to have the pipes repaired to prevent further damage. If the pipe problem arises from material build-up then the plumber can use a different approach like hydro blasting.
We offer Hydro excavation services, for cost or a quote, please give us a call.
There are times when it’s virtually impossible to dig around underground assets such as water pipes, telecommunication cables and gas pipelines. Without a detailed map of your underground assets, you might end up dealing with costly damages. Hence, instead of using traditional techniques in excavation, it’s highly advisable to use hydro evacuation. It’s a fast, risk-free and effective digging method that can be used for both commercial and residential customers.
A brief introduction into hydro excavation
Hydrovacing or hydro evacuation was first introduced back in the 1880s when miners needed to utilise pump pressurized water to wash away debris and even large land masses. This technique allows for faster and more convenient way of capturing gold plus other minerals from the ores.
Fast forward to 1969, a more sophisticated tool was invented, which they referred to as ExcaVactor. A decade after, companies offering pipe excavation services started using sewer cleaners and vacuum trucks to conduct the hydro evacuation procedure. In some companies, it’s offered alongside solutions such as the sucker truck and unblocking services.
It’s a technique used in a lot of applications. Be it a residential property or a large commercial building, hydrovacing can come extra handy in excavating debris, removing damaged pipes and more.
What happens during a hydro
Instead of digging the old-school way, hydro evacuation involves the use of pressurized water. Water is injected into the ground until the soil appear like a slurry mixture. Then, the workers need to feed the liquefied soil into the pipes of a sucker truck. The powerful vacuuming tool is strong enough to remove around 70 feet of liquefied soil.
The best part about this process is it works for any type of soil. Be it a loose garden soil, a mixture of silt and clay or even frozen ground, you can have your pipes or other underground assets dug up safe and fast.
What are the benefits of hydro evacuation?
Choosing hydro evacuation over the old digging method can help you solve all kinds of problems without risking infrastructure damage. It also provides you with a safer way for you to uncover defective underground assets. On top of that, it offers a lot of perks including:
Reducing cave ins resulting from the disruption of the surrounding soil
Faster completion of your excavation project
No need to use additional equipment because only water, air and sucker truck is required
Zero to minimal damage to pipes or other underground assets
Does not require additional workforce to remove soil underneath the excavation site
Works for a variety of soil types including permafrost
Can be used in hard to access locations because truck can be positioned at most 100 feet away from the site
Applications of hydro evacuation
There are many ways you can maximize the use of hydrovac. Here are some of its most common applications in both residential and commercial properties:
Excavation of tight spaces – Sometimes property owners have a hard time excavating because of their cramped space. Good thing, tight spaces are not an issue when hydro evacuation is used. The equipment can be placed in a distant area during the service so the workers have enough space to work on.
Removal of debris – Dealing with debris stuck in pipes and manholes can be quite a nightmare. With hydrovac, you get to remove debris before they even get stuck inside the drain or pipes.
Excavation during cold season – Working during the cold seasons comes with a lot of health hazards. However, sometimes issues such as frozen or burst pipes just happen. Thankfully, you have a better and more hassle-free option to dig up your damaged pipes. Hydrovac works seamlessly even with completely frozen soil.
Slot trenching – Widen trenches safely and quickly with hydrovacing. It will help you find utility lines more conveniently and safely if you use pressurized water to dig and widen trenches.
Potholing – Need to check underground facilities? You can do so without risking the integrity of the building’s structure. Hydro evacuation eliminates risks and allows you to work in congested areas.
Setting of poles – If you need to some pole drilling work done, booking a hydrovac service will also come extra handy. Hydro evacuation is the most highly recommended method to use in setting poles.
Utility and pipeline crossing – Working in an area with many pipes and utility crossing is a tricky process. One wrong move can result in very expensive repairs. This why it’s better to make use of hydrovac. It’s a simple yet sophisticated technique that help you move forward with work at a faster pace.
Hydrovacing is perhaps one of the most efficient methods used to excavate materials today. It’s works fast so you’re sure to get your project done within your projected time frame. The service is also made cost-effective so you enjoy more value for your money. Call Drainage.nz today for your hydro evacuation needs.
Dealing with blocked drainage can be very cumbersome. However, it’s important to get it done as soon as possible to avoid paying for expensive repairs. With a clogged sewer line, waste water can’t flow down the line drain. Instead, the water flows back into the pipes inside a house or a commercial building. For many people, this means trouble, especially when the waste water starts damaging the property and leaving an undesirable scent.
Causes of a clogged drainage
Clogged drain pipes are perhaps one of the most common issues faced by many property owners. And there are plenty of reasons why this happens. Here are some of the common causes of a blocked drain:
Hardened grease, oil, fats and decaying food particles
Chemical buildup from bathroom products such as toothpaste, soap, and shampoo.
Flushed toilet paper, paper towels, wet wipes and sanitary napkins/tampons
Soil or construction debris during a home renovation project
Deteriorating plants or leaves during autumn
Offset drain pipes, especially in old properties
Mineral buildup inside the pipes because of hard water
Signs your drain is blocked
It’s not easy to figure out when a drain pipe gets blocked, mostly because the system is underground. Most of the time, people don’t even know that they have blocked drainage until the damage is beyond repair. Thankfully, there are some key telltale signs that your drain is blocked:
Unpleasant smell coming from the drain – One of the most obvious signs that you have a clogged drain pipe is foul sewage odour. Organic matter breakdown releases unpleasant smelling gases such as carbon dioxide, hydrogen sulfide and nitrogen.
Toilet won’t flush or the water level is too high – You know there’s something wrong with the drain pipes when the water in the toilet bowl looks abnormally high.
You hear a gurgling sound from the pipe – A gurgling noise coming from the plug hole, drain and toilet bowl can also denote that there is a buildup of grease, dirt or other material in the drain.
Water keeps on backing up to your tub, sink and shower –
Water on the kitchen, laundry or bathroom floor –
Dealing with a clogged drain
If you see any of the signs enumerated above, you need to act fast. It might be worth it to use DIY remedies to unclog the pipes, especially when the problem is not that serious. After all, who doesn’t want to save a few dollars on a survey.
However, most of the time, it’s more practical to call in a drain unblocking professional. It saves you time and money, plus you don’t need to figure out your problems on your own. With the help of a trained plumber, you get to the bottom of the issue fast and you prevent other expensive problems to arise.
Here are some of the ways that experts use to unblock drain pipes:
Mechanical unblocking – The standard process to deal with a blocked drain involves the use of equipment such as motorised drain snake. The service charge starts at $295.
Camera inspection – There are some instances where plumbers need to use a camera to inspect drain. With CCTV drain survey, plumbers get to identify what is blocking the drain.
Hydro blasting – Hydro- jetting or hydro blasting is a technique used to clean or clear out surfaces or pipes. It involves the use of highly-pressurized water to dislodge materials.
For severe cases, you may need to avail additional services such as pipe excavation. The process involves the removal and replacement of the blocked pipes. The service can cost around $229 if its a basic dig up and replace.
Besides dealing with the blockage, you should also consider having your pipes cleaned on a regular basis. You can book a sucker truck service for $207 so you can get rid of organic matter accumulating inside the drain pipes.
You can also install sediment water filter cartridge to minimise the amount of soil, rocks, and silt accumulating in the drain.
Lastly, if you make use of an underground grease trap, see to it that you have it cleaned every once in a while. Without a clean grease trap, more fat, oil and grease or FOG end up in the drain. And overtime, they accumulate and cause plumbing mishaps aka blockaghes.
How to prevent clogging of drain pipes
Clogged drains are quite annoying but at the same time, preventable. After a plumber restore it to good condition, your next priority is to keep it that way for a long time. It will help you avoid trouble plus paying for additional or follow up services. Here are the simplest and most practical ways you can keep your drain clear:
Never dump leftover food in the sink
Allow liquid grease to cool and have them disposed properly
Do not pour fat or oil in the kitchen sink
If the main line supplies hard water, use a water softener to prevent material buildup
Utilise hair catcher on the drain to prevent hair from getting into the pipes

If you are experiencing one of the following issues:
Flooding Basement area
Water under house
Blocked stormwater drains
Subsoil drainage problems
Excessive water accumulation
Then you need to think about a permanent long term solution if you care about the property. Whether you intend to sell or keep Long term solutions mean more value and more safety for the occupants and/or owners.
Drainage NZ have been doing subsoil drainage and providing flooding solutions for over 20 years! Our solutions are cost effective and you only pay once to have the problem solved first time.
Some recent flooding issues Drainage NZ has resolved
A drainage solution is not just finding someone that can dig a hole and throw a punched Nova coil into the ground. There needs to be an understanding of physics and a plan needs to be engineered which is closely linked to the issues you are facing.
Subsoil Drainage Solutions
Drainage NZ have been involved in 100s of subsoil drainage solutions around the larger Auckland area. We have done everything from engineering soak holes to providing unique thrusted and/or drilled solutions for home and business owners that assumed no solution existed.
In Auckland you will find several extreme ground conditions. Whilst in Mt Wellington you may have volcanic ground, in West Auckland or on the North Shore you will find many areas are meters deep in clay that offers zero ground percolation. Where the one offers plenty of soakage the other will offer none but both have one thing in common requiring an engineered methodology to tackle the different forms of flooding that are affecting properties.
Our solutions also include many properties that are affected by no available public storm water networks requiring self-management of roof and surface water.
Consents and Plans
If and when design and consent are (e.g in some instances pumped solutions) required Drainage NZ take care of everything. We have designers in-house that work closely with our field technicians to achieve your desired scope successfully.
Here some subsoil drainage jobs Drainage NZ have completed recently.
Location: West Auckland Problem: Basement flooding (water leaking into room below ground and garage areas) Depth: 1.6 meters Length: 26 meters Scope: Excavation, waterproofing, drainage works. Reinstatement and landscaping and concrete works. Outfall: Existing Private SW to Public Stormwater
Location: Central Auckland (Mt Wellington) Problem: Excessive Flooding into house areas below external outside area. Depth: 1.5 meters Length: 15 meters Scope: Rock breaking, Excavation, waterproofing, drainage works Outfall: Existing Onehunga Soakhole
Location: North Shore Problem: House piling flooding. Incorrect onsite levels introduce excessive water to areas under house resulting in piling slipping, cracked walls and framing in upper levels. Depth: 1.2 meters to point of discharge. Scope: Excavation of clay, leveling ground, waterproofing, drainage works Outfall: Existing Private Soak hole
In our day-to-day lives, all of us normally wake up fresh out of bed, brush our teeth, take a bath, eat our breakfast, wash the dishes, water our plants, and so much more. Well, have you ever noticed that most of what we do every day requires the use of water?
Are you aware of the fact that every time you turn on the faucet, the water you most likely use will go down the drain to somewhere most of us don’t even know anything about? We just wash our hands, look at the water drain, and turn it off.
How Drainage Works
The process of draining water is way more complicated than you think. The water runs down a hole, into small house pipes, into bigger council pipes, for many kilometers to then arrive at its destination.
In most cases, not everyone knows the difference between sewage and sewerage. Is it the same thing or two completely different things. Today, we are going to look at what those two words really mean, as a learning matter and something that may benefit anyone searching for a definition.
What Is Sewage (the poo)?
Before the 20th century, sewage was usually
discharged into a body of water such as a stream, river, lake, bay, or ocean.
There was no treatment, so the breakdown of the human waste was left to the
ecosystem. Now, the word “sewage” refers to liquids or waste matter usually
carried off by sewers.
In the modern world, the word sewage is slowly being replaced by the word “waste water,” also meaning that any water that has been affected by human use, making these two words similar in the way that in the end, we humans produce waste that is to be carried out by any means of transportation, such as sinks, tubs, showers, dishwashers, clothes washers, toilets, pipes, etc.
It can be also referred to as domestic wastewater or municipal wastewater that is produced by a community of people. It is characterized by volume or rate of flow, physical condition, chemical and toxic constituents, and its bacteriologic status.
Sewage usually travels from a building’s
plumbing either into a sewer, which will carry it elsewhere, or into an onsite
sewage facility. Whether it is combined with surface runoff in the sewer
depends on the sewer design.
The reality is that most wastewater produced globally remains untreated causing widespread water pollution, especially in low-income countries. As well as many developing countries the bulk of domestic and industrial wastewater is discharged without any treatment or after primary treatment. It may not seem like it, whether or not these are good for the environment or not, but once you see the fuller picture of how much the sewage actually helps us in our day to day lives, it makes a huge difference.
What Is Sewerage (what carries the poo)?
On the other hand, the word “sewerage”
refers to the provision of drainage by sewers. Sewerage is an infrastructure
that transports sewage, like storm water, meltwater, rainwater, by using
sewers. It encompasses components such as receiving drains, manholes, pumping
stations, storm overflows, and screening chambers of the combined sewer or
Sewerage opens an entry to a sewage treatment plant or at the nearest point of discharge into the environment. It is a system of pipes, chambers, manholes, etc. that holds the sewage from the waste makers above.
In American colloquial English, “sewer
system” is applied more frequently to the large infrastructure of sewers
that British speakers more often refer to as “sewerage”. Almost all
the countries of the world have sewerages, but this does not mean that they are
the best of ones.
Countries like New Zealand, Venice, and Amsterdam have a great sewerage, and on the spectrum, we also have countries like Bangladesh, India, and other third world countries that need help in making better sewerage’s for their citizens.
To sum things up, these two work hand in
hand. One cannot work without the other and vice versa. A sewage is a part of a
sewerage and a sewerage is a part of a sewage.
The simplest way to explain the two different words is this – sewage is the waste that is produced by people while sewerage is the structure that holds the sewage within its “stomach.” In the end, it is only us humans and the rain that uses these systems, and we need to make sure that these two things will be used correctly in our lives, making sure to clean the area properly, separating water-type waste and solid-type waste, so that it – the waste water – would be easier to recycle.
