Stop sewage overflows and leaks
Sewage overflows can occur due to various reasons, including blocked or damaged plumbing, backflow from the sewerage system, a malfunctioning septic tank, or flood water containing sewage. These overflows can have adverse effects on human health, causing illnesses such as skin rashes, eye and ear infections, and gastroenteritis due to the harmful microorganisms present in sewage. Here are some ways to address this issue and prevent sewage overflows and leaks:
Identify the Source
The first step in addressing a sewer overflow is identifying its source. Check for visible signs of sewage, such as foul odours, standing water, or unusual wet patches in your yard. Determine if the problem is confined to your property or if it extends to the main sewer line, which may be the local council's responsibility.
Seek Professional Help
If the problem seems confined to your property, contact a professional plumber. They can assess the situation, identify the cause, and provide tailored solutions. For issues with your septic tank, such as silt and debris buildup, contact a licensed contractor to pump it out safely.
Maintain Your Sewerage System
Proper maintenance of your sewerage system is crucial. Ensure that any faulty, blocked, damaged, broken, or worn-out parts are repaired or replaced promptly. Regular maintenance helps prevent overflows and reduces the risk of contamination.
Implement Nature-Based Solutions
Nature-based solutions, such as blue-green infrastructure and sustainable drainage systems, can play a vital role in reducing sewage overflows. These solutions aim to work in harmony with natural processes, minimising the impact on the environment.
Separate Foul and Surface Water
Separating foul water (sewage) and surface water (rainwater runoff) can help manage sewage overflows. By directing surface water away from the sewage system, you can reduce the burden on the pipes and treatment plants, minimising the risk of overflows.
Store Stormwater in Tanks
During heavy rainfall, stormwater can overwhelm combined sewer systems, leading to overflows. One solution is to store stormwater in large tanks temporarily and then gradually release it back into the sewer system after the storm has passed. This method helps reduce the immediate pressure on the system.

Reduce stormwater runoff
Stormwater runoff is rain that falls on streets, parking areas, sports fields, gravel lots, rooftops, or other developed land and flows directly into nearby lakes, rivers, and oceans. As stormwater passes over developed land, it picks up pollutants and transports them to the nearest storm drain, eventually flowing into rivers and bays. This runoff is a major source of nutrient pollution, carrying nutrients from lawns, streets, and rooftops into water bodies.
To reduce stormwater runoff, individuals can make changes to their daily habits and landscaping practices. Directing roof downspouts into a rain barrel or vegetated area can help reduce runoff by capturing and slowly releasing rainwater. Native, drought-resistant plants can also be used to replace water-intensive lawns, reducing the need for irrigation and decreasing the amount of stormwater runoff.
In addition to these measures, individuals can practice good septic and cesspool care. This includes maintaining and regularly inspecting septic systems to prevent overflows and leaks. It is also important to dispose of household chemicals properly, as pouring them down the drain can interfere with wastewater treatment processes and pollute the environment.
Communities can also play a role in reducing stormwater runoff. Protecting and expanding natural areas, such as street-side swales and pervious concrete sidewalks, helps prevent stormwater from rushing into sewers by allowing it to filter through the soil. Implementing green infrastructure, such as rain gardens, pervious pavement, and green roofs, can also slow down and infiltrate stormwater, reducing the impact of runoff.
Furthermore, maintaining vehicles and properly disposing of automotive fluids can help reduce stormwater pollution. Leaks and spills from vehicles can contaminate stormwater, so it is important to regularly check and repair fluid leaks and recycle motor oil and other automotive fluids. Washing vehicles in areas where water can filter into the ground, such as on lawns or landscaped areas, can also help prevent polluted runoff from entering storm drains.

Maintain and upgrade infrastructure
Maintaining and upgrading infrastructure is crucial to combating sewage pollution. This involves addressing the inadequacies of existing systems and implementing innovative solutions to ensure effective wastewater management. Firstly, regular maintenance of septic systems is vital. Prompt replacement of cracked or broken pipes prevents sewage seepage and reduces the risk of leaks and spills that can contaminate water sources. This is especially important in older sewage systems, where stormwater combines with household sewage, increasing the likelihood of overflows and discharges of untreated wastewater.
Upgrading infrastructure also entails investing in advanced wastewater treatment systems. Many communities still rely on outdated cesspools and septic systems, which allow household waste to leach into ground and surface waters. Connecting these households to centralized sewers or more modern wastewater treatment setups is essential to intercepting and treating sewage before it reaches local waterways. This investment in infrastructure should be accompanied by proper planning to accommodate growing urban areas. As cities expand, the amount of stormwater surging into sewers increases, exacerbating the problem of sewage overflows. Implementing green infrastructure and low-impact development practices can help mitigate this issue by encouraging rainwater to soak into the ground rather than becoming runoff that carries pollution into waterways.
In addition to these measures, conserving and expanding natural areas can play a crucial role in preventing stormwater from rushing into sewers. For instance, street-side swales and pervious concrete sidewalks in Seattle help filter stormwater through soil, reducing runoff into city sewers. Similarly, directing roof downspouts into rain barrels or vegetated areas, replacing water-intensive lawns with native plants, and adding mulch to landscaping can all contribute to reducing runoff and the burden on sewer systems. These natural solutions not only lessen the impact of stormwater but also enhance the absorption and retention of rainwater.
Furthermore, maintaining and upgrading infrastructure extend beyond physical systems. It is imperative to address the root causes of sewage pollution, which often stem from poor waste management practices. This includes ensuring that waste, especially hazardous materials and non-biodegradable items, are disposed of correctly. Proper waste disposal significantly reduces the contamination of water sources and helps alleviate the strain on sewage treatment facilities. Additionally, educating communities about the impacts of their actions is vital. Encouraging individuals to only flush the three Ps ("pee, poop, and toilet paper") can prevent clogs and blockages in septic tanks and sewers, reducing the risk of sewage backing up into streets and homes.
Lastly, maintaining and upgrading infrastructure require consistent funding and regulatory enforcement. Water companies and governments must prioritize investments in wastewater management and hold polluters accountable. The weak enforcement of existing regulations has, in some cases, allowed water companies to profit from pollution and shirk their responsibility to protect the environment. Strengthening oversight and increasing funding for maintenance and upgrades are crucial steps toward ensuring the proper functioning and longevity of sewage infrastructure.
