Signs of Impending Basement Flooding: How to Recognize the Early Warning Signs

Checkout the video below. Basement flooding can cause big problems for homeowners, from damage to health issues. Luckily, spotting the early signs of potential basement flooding can help you act before it’s too late.



Whilst in most cases flooding can be predicted, often and especially with the increase of rainfall here in New Zealand,  flash floods are becoming more common. Homes that have never flooded before are experiencing first-time events. Why is that and is there a way to identify whether your home could be next?

Unlike European countries, when we refer to a “basement” here in New Zealand, we refer to any area of the house that is below the outside ground level. 

If you can identify cracks in the concrete or block walls, it is very likely this is the effect of water finding its way into areas it shouldn’t. 

Let’s review some indicators.

1. Musty Odor

If your basement starts to smell musty and damp, it may be a sign of excess moisture and potential water infiltration.

2. Cracks in the Foundation

Inspect your basement’s foundation for visible cracks. These cracks can let water seep in and eventually lead to flooding.

3. Water Puddles Outside

Water collecting around your home’s foundation after rain can find its way into your basement. Proper drainage and grading can help prevent this.

4. Damp or Stained Walls

Damp or stained walls in the basement indicate moisture getting in. These stains can worsen and suggest possible flooding.

5. Blocked or Overflowing Gutters

Clogged gutters can cause water to overflow and enter your basement. Keep your gutters clean and well-maintained.

6. Sump Pump Problems

If your sump pump isn’t working correctly, it can’t remove water effectively. Regularly check your sump pump to ensure it’s in good working condition.

7. High Water Tables

Areas with high water tables are more prone to basement flooding. Understanding local groundwater levels can help you prepare better. Be proactive and check your home’s LIM report to identify whether your home is subject to Flow Paths or Flooding zones. If this is the case, Drainage NZ can help you be prepared for such an event before it’s too late. 

9. Rising Utility Bills

Sudden increases in water and energy bills may indicate hidden leaks or water infiltration that could lead to flooding.

10. Water Stains or Peeling Paint

Concrete block calcification, water stains or peeling paint along basement walls suggest water intrusion. We can investigate the source to prevent this. This includes treatment of block work and timber. 

11. Unusual Sounds

Strange noises like gurgling drains can be early signs of drainage blocking, which can lead to basement flooding if not addressed. Get drain unblocking service right away to avoid extensive damage. 

12. Condensation on Windows

Excess condensation on basement windows can indicate high humidity, contributing to basement moisture and potential flooding.

13. Changes in Landscaping

Noticing major changes in your landscaping, like slopes toward your home, may direct water toward your foundation, increasing the risk of basement flooding.

14. Weather Patterns

Stay informed about local weather forecasts, especially during heavy rain or snowmelt periods, which can increase the risk of flooding.

15. Health Symptoms

Many underestimate the effects of long term exposure to non visible water problems. 

Increased allergies or respiratory issues can indirectly indicate moisture and mould growth in your basement, often linked to flooding or water ingression.
Recognizing these early warning signs is the first step in preventing flooding or long term damage. Regular checks, maintenance, and swift action are vital to safeguard your home from this costly and stressful issue. By staying alert and taking necessary precautions, you can significantly reduce the risk of basement flooding and its related problems.

Achievement of Significant Drainage Milestone in Project Auckland: Hiwa-i-te-Rangi


Watercare’s gigantic Tunnel Boring machine, known as Hiwi-i-te-Rangi, has recently reached a noteworthy achievement during its excavation of the Central Interceptor Tunnel. It has successfully achieved the halfway point of its 14.7-kilometre journey to central Auckland, marking this remarkable feat with a breakthrough into a shaft at May RD in Mount Roskill.

The Central Interceptor project is hailed as the largest wastewater infrastructure endeavour in New Zealand’s history, holding the promise of seriously addressing wet weather overflows into waterways and the Waitemata Harbour. Furthermore, the tunnel will intersect with two link sewers connecting the Mangere Wastewater Treatment Plant and Grey Lynn.

Amidst the jubilant cheers of construction teams, Shayne Cunis, the Executive Programme Director of Watercare Central Interceptor, announced the breakthrough of the cutter head, with a diameter of over five meters, through a 69-meter-deep shaft wall. Cunis emphasized that despite the considerable challenges faced, this breakthrough signifies a crucial moment in the project’s progress.

Cunis urged everyone to take a moment to appreciate this significant achievement, emphasizing that the project remains on track to meet its planned 2026 completion date, despite obstacles such as COVID-19 lockdowns, closed borders, global shipping delays, and adverse weather events. The top priority remains ensuring the safe delivery of the project.

According to Cunis, one of the most thrilling moments in the project journey thus far was the 2022 crossing of Manukau Harbour, spanning from Mangere Bridge to Hillsborough. Underwater tunnels are a rarity in New Zealand, and this 1500-meter section was completed in less than 11 weeks.

The Central Interceptor project has reached several milestones. Following the completion of the undersea bridge in December 2022, the first link sewer, responsible for collecting flows from Mount Roskill and Blockhouse Bay, was finished in March of this year. Construction has also commenced on a second link sewer, set to be built in two segments, intersecting the main shaft at Wairere Avenue in Mount Albert.

Cunis extended his appreciation to the construction partners of Ghella Abergeldie JV, as well as the dedicated teams from Jacobs, AECOM, Delve Underground, Watercare, and the subcontractors. He acknowledged their tremendous efforts in ensuring the project’s successful delivery.

Francesco Saibene, the Project Director of Ghella Abergeldie JV, also commended his tunnelling team for their hard work, emphasizing that reaching the halfway point is a moment of celebration for all involved.

Meanwhile, significant progress is being made on the nearby Mangere Pump Station project, where six pumps and inflow pipes are being installed to facilitate the transfer of flows from the main tunnel to the treatment facility for processing.

The planned timeline includes completing both the connection sewers and Section 1 of the primary tunnel, stretching from May Rd south, by the middle of 2024. Initiating the first segment will relieve strain on the aging Western Interceptor.

Cunis emphasized that resilience has consistently been a primary motivator for this project, alongside the objectives of accommodating future expansion and delivering environmental benefits. Once Section 1 becomes operational, Watercare’s operations teams will have the opportunity to perform essential maintenance on the Western Interceptor.

These upgrades are exciting for all drainlayers in the Auckland area. As our infrastructure grows more and more exciting drainage developments will take place. Drainage NZ specialize in Public and Council drainage works, if you have a project planned, why not have us tender for you.

We do Driveway and Garage Channels. Domestic and Commercial.

We do Driveway and Garage Channels. Domestic and Commercial.

Driveway channel drains are also called trench drains, drainage channels, or linear channels. These are linear drainage systems that are frequently used and commonly installed to immensely reduce the amount of excess water in your driveway, around swimming pools, decks & retaining areas, pedestrian areas, and more. This type of drainage system provides efficient management of surface water.

Materials used in channel drains

Plastic Channel Drains – Plastic or polypropylene drains offer the best balance between ease of use, shipping, and costs. It’s proven high-performance even if it is considered fragile or not very strong. This material has many advantages, including the following:

  • non-toxic
  • odor-free
  • lightweight
  • It does not absorb water. Resistant to temperature changes. 
  • Unaffected by solvents, acids, and wear. 

Concrete Channel Drains – are more robust and have higher chemical resistance. Concrete channels have the benefit of being cost-effective compared to other materials on the market. It also has a high resistance to compression. Compared to others, the only disadvantage this material has is that it is a weighty material.

Grating Material – Grating is commonly used in commercial locations. It’s the most efficient way to gather overflows, but the space at the top is installed so that people will not get their feet caught in the drains. Grating styles are called longitudinal slots, perforated gratings, mesh gratings, horizontal slots, solid gratings, heel-proof gratings, and diagonal slotter gratings.

Weight load classes

When selecting channel drainage, it’s crucial that you consider the weight-loading requirements before deciding which system to place in a specific area. Loading requirements are categorised into six standard classes, which are:

  • A15 – Light duty, pedestrian areas; gardens, patios, and driveways
  • B125 – Driveway for family cars, vans, and 4x4s.
  • C250 – Parking sides and small private car parks
  • D400 – Roadways; High traffic, public car parks.
  • E600 – Industrial, loading bays, cargo handling area.
  • F900 – Extreme Duty Applications; Docks and airports.

Blocked Drains, why, how, who?

A blocked drain results when anything becomes lodged in the pipes and prevents proper water flow. It’s like when a boba clogs a straw, and you can’t drink through it. A similar thing can happen in the pipes that eliminate water from our toilets, sinks, and showers. The water cannot drain properly when plugged, and it may overflow or take a long time. Clogs may happen by flushing so much toilet paper, food, or hair. It is critical to unblock congested drains so that water can flow freely once more. Drain jams are a frequent household annoyance that can have an important impact on both individuals and the larger community. Although these obstacles appear insignificant at first glance, they can have several negative effects beyond simple uneasiness. This topic explores the negative effects of blocked drains and illustrates how they affect infrastructure, health, hygiene, and the environment.

Plumber, repair. Experienced attentive middle-aged man carefully examining bottom of kitchen sink touching pipe with his hand diagnosing problem

Blocked drains can arise for many reasons, including the buildup of debris and foreign objects. Materials like hair, soap scum, food particles, plastics, and grease can build up inside the drain pipes over time, causing blockages. Improper disposal of waste materials is a significant human cause of blocked pipes. Pieces of stuff such as wet wipes, cotton balls, dental floss, sanitary products, paper towels, and small plastic stuff are often carelessly discarded into drains and toilets, hindering water flow. Non-biodegradable items like wet wipes and paper towels flushed down the toilet can also cause sewage system obstructions. Pouring grease or oil down the kitchen sink can solidify and tighten the pipe, disrupting water flow. Aged or damaged pipes can be another cause of blockages. Corrosion, cracks, or pipe failures can reduce water flow or complete blockage. Misaligned pipe sections can create areas where solid waste accumulates, leading to blockages. Understanding these causes can help prevent blocked drains and the associated inconveniences.

Let’s move on to the consequences and negative impacts of blocked drains as we address the causes earlier. Firstly, in our bodies. Blocked drains may provide a place for dangerous germs, viruses, and pests, impacting someone’s hygiene and health. Water stagnant because of barriers provides a favorable environment for bacteria, raising the risk of illnesses and disease. In addition to lowering indoor air quality, foul smells from clogged drains can make people feel uncomfortable and have respiratory problems. Next is infrastructure damage. It is when drains are clogged; excess water may back up and exert pressure on the plumbing system. This pressure can cause pipes to burst, leading to costly repairs and property damage.

Additionally, the accumulation of trashes in drains can erode pipes over time, compromising the integrity of the entire drainage network. Another major implication is environmental concerns because blocked drains can overflow wastewater into nearby water bodies, such as rivers or lakes, causing pollution. Contaminants carried by the excess, including chemicals and debris, can harm aquatic ecosystems, disrupting the balance of marine life and compromising water quality. And lastly, economic impact. The economic consequences of blocked drains are twofold. Firstly, individuals may experience expenses for repairs and maintenance. Secondly, the community bears the burden of increased healthcare costs due to the spread of waterborne diseases. Additionally, infrastructure damage caused by blocked drains demands public funds for repairs and can lead to troubles in transportation and commerce.

Despite seemingly unimportant, blocked drains have major and broad aftermaths. These obstacles impose immediate attention and preventive measures because they put hygiene and health at risk, damaging infrastructure and degrading the environment. People and communities may reduce the risks associated with clogged drains and protect the health of both people and the environment by increasing knowledge of the consequences and carrying out routine maintenance.

Is your property protected against flooding?

The weather in New Zealand is changing. More and more properties are feeling the effect of our record rain fall as storms like Gabrielle become the norm in this decade. In fact, Aucklanders suffer the wettest month in history! Article Here by NIWA.

This ultimately means that many conventional methods of managing stormwater in the Auckland area may need to be reassessed, revalued and improved.

This of course starts with our Public Systems that are already struggling with the volume of water being managed. Our overwhelmed Stormwater systems are also affecting our Sewer system in the Auckland areas. During heavy rains, this leads to overflowing gully traps and sewage flooding onto lawns and even into properties.

Watercare and council have been tackling cross connection issues for years using methods such as smoke but as they continue to successfully separate stormwater and sewer they are faced with the consequences of this ongoing extreme wet weather.

In the images below, Watercare is testing a suspected private line to ensure SW and SS are not connected together. The apply smoke to the sewer line and if smoke exits the stormwater then there is evidence that the two are connected. It is the home owner’s responsibility to remedy the problem.

Whilst planning and action is underway, it takes time for our councils and government to improve NZ’s infrastructure and in the meantime, where does that leave you as a property owner?

If you property is affected by one of the following scenarios, then you will also be affected by the record rain. Especially homes that were built pre 2000.

Scenarios:

  • If a portion of your property is below ground. E.g. The ground outside is higher than the floor inside. The more sides of the property below external ground level, the more flood prone the property is.
  • Your property is located down the hill or down a shared driveway. The saying goes, “The property down the hill pays the bill”. Subsoil Solutions required.
  • Your property operates a charged water discharge system where downpipes are sealed pushing water upstream.
  • Your stormwater discharge is going into a soakhole. Most likely installed in the 70s and most likely never serviced.
  • You don’t have a public connection and your SW and SS is combined integrating a Buchan trap.
  • Your Garage floor is the lowest point and does not offer a step up.
  • You rely on external channels and residential cesspits that are not doing a great job.
  • Damaged and blocked drains needing constant Drain Unblocking.

If any of the above applies to you, you have come to the right company to assist with solutions that are not only permanently effective but also affordable.

Solving the Mystery of a Leaking House: How to Identify & Fix Water Leaks in Your Basement

Discovering a leaking house can be a disheartening experience. You can spend hours searching for the source of the leak only to come up empty-handed. Unfortunately, water leaks are a common problem in many homes, especially those with basements. Fortunately, there are steps you can take to identify and fix water leaks in your home. This blog will discuss the common causes of water leaks in homes, how to fix them, and how to prevent further leaks. Read on to learn more about how to solve the mystery of a leaking house.

What to Do When You Discover a Leaking House

If you discover that your house is leaking, the first thing to do is assess the damage. Take note of any visible signs of water damage, including water stains on the walls and ceilings, mould, and warped floors. If you suspect a water leak, locate the source of the leak as quickly as possible. This will help you determine the best way to address the problem.

The most important thing to remember is that water leaks can cause serious damage if left unchecked. It’s essential to act fast to avoid costly repairs down the line. If you’re concerned about the safety of your home, contact a professional to inspect the area and make the necessary repairs.

What Causes Water Leaks in Your House?

There are a variety of factors that can cause water leaks in your house. The most common culprit is ground water entering a home when it is buried underground and having nowhere else to go but inside your home.

In some cases, the source of the leak may be difficult to pinpoint. If this is the case, it’s best to call in a professional to help you identify the source of the leak. A professional can quickly pinpoint the source of the leak and make the necessary repairs.

Identifying the Source of the Leak

The first step in solving the mystery of a leaking house is to identify the source of the leak. This can be a tricky process, as the source of the leak may not be immediately apparent.

Start by looking for any visible signs of water damage, such as water stains on the walls or ceiling, mould, or warped floors. If you can’t find any obvious signs of a water leak, it’s time to start looking for more subtle signs.

Check for any unusual smells or sounds, such as a musty smell or gurgling noises. You may also want to check for any signs of moisture or dampness in the walls, floors, and ceilings. If you can’t find any visible signs of water damage, it’s time to call a professional. A professional will be able to pinpoint the source of the leak and make the necessary repairs.

Common Causes of Water Leaks in Basements

Basements are one of the most common areas for water leaks. This is because basements are usually the lowest point in the home, making them susceptible to flooding.

The most common cause of water leaks in basements is poor drainage. If your basement has no means of diverting ground water away from the home then it will enter the home instead. Water can easily seep in and cause damage.

Drainage Subsoil Solutions

If the source of the leak is poor drainage, you may want to consider installing a drainage subsoil system. A drainage subsoil system is designed to redirect water away from the house, preventing it from seeping in and causing water damage.

The drainage subsoil system consists of a network of pipes and trenches that are installed around the perimeter of the house. The pipes and trenches are designed to collect and divert water away from the house, preventing it from seeping in and causing damage.

This type of system is relatively lengthy and expensive to install but is the most effective way to prevent water damage long-term. If you’re concerned about the safety of your home, it’s best to call in a professional to install the system for you.

How to Prevent Future Leaks

Once you’ve fixed the source of the leak, it’s important to take steps to prevent future leaks. Whilst all the trenches are open around the home, the drain layers would seal up any obvious entry points to the home such as cracked bricks or holes in the walls. The drain layers also apply 2 coats of waterproof paint as a precaution to prevent any more water from entering the home.

DIY or Hire a Professional?

When it comes to fixing a leaking house, it’s important to decide whether you’ll do the repairs yourself or hire a professional. While it’s tempting to attempt DIY repairs, it’s usually best to call in a professional. This is because water leaks can cause serious damage if left unchecked. A professional will be able to quickly identify the source of the leak and make the necessary repairs.

If you want to get Drainage NZ to look at your house to see what can be done to stop the water form getting in, they offer a free consultation. During the consultation, they’ll inspect your home and provide you with a detailed report on the best way to address the problem.

Uncover Hidden Problems in Your Home with a CCTV Inspection!

It’s no secret that our homes are often the source of many of our biggest headaches. Whether it’s broken pipes, blocked drains, or simply an area of the house that needs a bit of TLC, we often find ourselves searching in the dark for a solution. But what if there was a way to quickly and accurately identify the issue and get it fixed? Well, that’s where a CCTV inspection comes in.

Introduction to CCTV Inspections
A CCTV inspection is the use of a closed-circuit television camera to inspect a home’s plumbing and drainage system. This type of inspection allows professionals to “see” inside the pipes and pinpoint any potential problems. It’s an invaluable tool for plumbing and drainage professionals and homeowners alike, as it allows for quick and accurate diagnosis of any issues.

The process is simple. A CCTV camera is inserted into the pipes and moved along the length of the pipe. As it moves, it takes pictures and videos of the interior of the pipe, allowing the technician to identify any potential problems. This information is then relayed back to the technician, who can then determine what needs to be done to fix the problem.

What Can a CCTV Inspection Reveal?
A CCTV inspection can reveal a multitude of problems. From broken pipes to blocked drains, a technician can pinpoint the exact problem and provide a solution. It can also help to identify any potential problems before they become an issue. This is especially helpful in older homes, where it can be difficult to identify any potential issues without a thorough inspection.

Some of the most common issues that a CCTV inspection can reveal include:

Blockages in the pipes
Leaks or breaks in the pipes
Root intrusion
Corrosion
Structural damage to the pipes
Cracks or holes in the pipes

How to Prepare for a CCTV Inspection
Preparing for a CCTV inspection is relatively easy. Before the technician comes to inspect the property, it’s important to ensure that all of the necessary access points are open and easily accessible. This includes manholes, cleanouts, and other access points.

It’s also important to make sure that the area around the pipes is clear, as this will help the technician to get a better view of the pipes. If there is any debris or obstructions in the way, it’s important to remove them before the technician arrives.

Finally, it’s a good idea to make sure that the pipes are clean. This can be done by flushing them out with water and running a snake through the pipes if needed. This will help to ensure that the technician can get a clear and unobstructed view of the pipes.

What to Look Out For During the Inspection
During the inspection, the technician will be looking for a variety of different things. They will be looking for any signs of damage or corrosion, as well as any blockages or root intrusions. They will also be looking for any signs of leaks, as these can be extremely dangerous and need to be fixed as soon as possible.

The technician will also be looking for any structural damage to the pipes. This can include cracks, holes, or breaks in the pipes. This is especially important in older homes, as these types of issues can often go unnoticed and can lead to serious problems down the line.

Common Problems Revealed by CCTV Inspections
The most common problems revealed by CCTV inspections are blockages, leaks, and root intrusions. Blockages are caused by a build-up of debris or other materials in the pipes, which can block the flow of water. Leaks can be caused by a variety of things, including broken pipes, corrosion, or even structural damage. Root intrusions are caused by tree roots growing into the pipes, which can cause blockages and damage the pipes.

How to Fix Common Problems Revealed by CCTV Inspections
After a CCTV inspection, the technician will be able to identify any problems and recommend the best course of action. In most cases, the technician will recommend one of two options: water blasting or unblocking.

Water blasting is a process where high-pressure water is used to flush out any blockages or debris from the pipes. This is usually the most effective option for blockages and is also relatively quick and easy.

Unblocking is a more involved process, where the technician uses specialized tools to remove the blockage from the pipes. This process is usually used for more serious blockages, such as root intrusions.

The Benefits of Using a CCTV Inspection
There are a number of benefits to using a CCTV inspection. First and foremost, it can help to identify any potential problems before they become an issue. This can save homeowners a lot of time, money, and stress.

A CCTV inspection can also save homeowners money in the long run. By identifying any issues before they become serious, homeowners can save money on repairs and avoid any costly problems down the line.

Finally, a CCTV inspection is a great way to help maintain the health of your home’s plumbing and drainage system. By identifying any potential problems and addressing them quickly, homeowners can help to ensure that their plumbing and drainage system stays in good condition for years to come.

Important Considerations When Choosing a CCTV Inspector
When choosing a CCTV inspector, it’s important to consider a few different factors. First and foremost, it’s important to make sure that the inspector is qualified and certified. This will ensure that the inspection is performed correctly and that any potential problems are identified and addressed quickly.

It’s also important to consider the cost of the inspection. CCTV inspections can be expensive, so it’s important to shop around and find the best deal. It’s also important to make sure that the inspector is experienced and knowledgeable, as this will ensure that the inspection is thorough and accurate.

Tips for Maintaining Your Home After a CCTV Inspection
Once the inspection is complete, it’s important to take steps to maintain your home’s plumbing and drainage system. This includes regular inspections of all access points, such as manholes and cleanouts. It’s also important to make sure that all pipes are clear of debris and that any minor repairs are addressed quickly.

What is a Cesspit NZ?

A cesspit or catchpit is a drainage system used primarily in stormwater management. Whether it is sewerage or stormwater, a cesspit is designed to prevent blockages and water contamination in a drainage system. A cesspit is a chamber that allows debris and sediments to settle to the bottom of a pit. For this reason it is advisable to regularly maintain your cesspit by emptying and cleaning at least once a year.

Why do you need a cesspit?

A cesspit is typically found upstream of a drainage system. This way the cesspit can collect all debris before it enters public or private stormwater pipes.

Cesspits are most commonly found in gardens, driveways or roadways. These environments typically collect large quantities of debris and sediment which if allowed through would cause blockages in a public drainage system. A blockage could cause flooding, water to return back up a pipe or worse damage property. Therefore a cesspit is vital when managing surface water in any of these environments.

By law all channels and subsoil drainage must flow into a cesspit to ensure no debris can flow into the private or public stormwater lines. For example, a driveway channel may be a vector for debris to collect, and so all water must be filtered before it can be discharged into the stormwater line.

How does a cesspit / catchpit work

Basically, a cesspit works by providing a sump where sediment and debris can fall and collect. Water overflows at the top level of the cesspit leaving debris behind at the bottom of the pit. The clean water then exits through the outlet pipe, which sits just lower than the inlet pipe.

To protect the outlet pipe against potential floating debris, a baffle can be fitted to the outlet. This can help filter leaves and twigs, stopping them from entering the pipe.

Because silt, sediment and debris build up in the sump of the cesspit, regular maintenance and cleaning of the cesspit is required. Typically the average cesspit should be cleared out annually to prevent a build up of debris. Such a build up could cause the cesspit to become ineffective, increasing the likelihood of damage from unmanageable water.

Types of cesspits

The most common form of catchpit is a roadside catchpit. Catchpits can be found intermittently alongside Auckland roads. What is unique about these types of catchpits is their design. Roadside cesspit openings must not allow objects greater than 100mm in dimension to pass through. Openings must also be small enough to prevent sizable debris from entering the system that may cause damage. These cesspits are typically larger than ones found on residential property. Under New Zealand building code these cesspits are known as a type 2 surface water sump.

A type 1 cesspit is no larger than an office paper bin. These cesspits are commonly used in residential applications such as in a driveway or garden.

There are many different names for a cesspit, such as:

  • Catchpit
  • Bubble up chamber
  • Receiving chambers
  • wet chambers
  • Dry chambers

Regardless of the name, the principles are the same. Incoming water is filtered to remove contaminants before entering a larger drainage system. This now clean water can then be confidently reused, recycled, or safely discharged into our oceans or environment.

Cesspits come in a variety of materials. The physical sump is typically made of:

  • Concrete
  • Polyethylene plastic

The top grate of a cesspit is typically made of iron. Iron grates are extremely durable and heavy. This prevents the grate from blowing away in strong weather.

With the increasing popularity of bicycle lanes, a newly designed cesspit finish is becoming more common. This new design is a flat stainless steel grate. Unlike the normal curved iron grate, this cesspit finish is designed to prevent accidents on bikes and scooters. More traditional curved grates can act like a pothole, dismounting commuters off their bike.

Maintenance

Because a cesspit is a static installation designed to filter stormwater it can quickly become full. If Debris and sediment pile up it will cause a blockage, damage and even flooding. Therefore it is necessary to regularly maintain cesspits by clearing excess waste. Ideally this should be done yearly.

Every homeowner should be concerned whether their cesspit is functional or not. One quick test you can do at home is to look down into your cesspit. If you cannot see an outlet pipe then it most likely means your cesspit is overflowing or blocked.

Flooding: When council systems fail, what to do

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.

Managing Flooding

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.
