A Guide to Domestic Sewage Treatment Plants
While the vast majority of the UK's population relies on the main sewerage network to manage waste, approximately 5% of households in rural areas depend on off-mains solutions like septic tanks, cesspools, or domestic sewage treatment plants. Among these options, sewage treatment plants are often the preferred choice due to their effectiveness and efficiency.
Despite being highly efficient, installing a domestic sewage treatment plant requires careful consideration. These systems work by separating solid waste through sedimentation, purifying liquid waste via aeration, and decontaminating it to ensure safe discharge. Before deciding on a treatment plant, it's essential to understand how they operate and what factors need to be considered.
Key Takeaways:
- Domestic sewage treatment plants are commonly chosen for rural properties disconnected from main sewerage systems.
- These plants clean sewage waste through sedimentation, aeration, and decontamination processes.
- All treatment plants must comply with EN 12566-3 2005 standards, and planning permissions might be required.
- Regular maintenance is crucial to ensure compliance with environmental regulations and optimal performance.
One significant advantage of sewage treatment plants over septic tanks is their ability to handle larger volumes of waste and discharge cleaner effluent, typically around 95% pollutant-free. Unlike septic tanks, which require soakaway systems to avoid environmental damage, treatment plants can be installed almost anywhere, provided there's sufficient space and access to electricity.
When choosing a location for your sewage treatment plant, it's vital to adhere to building regulations. For instance, the plant must be at least seven meters away from any residential structures and ten meters from watercourses. Additionally, consider accessibility for maintenance and the potential for gravity-assisted flow to enhance efficiency.
Proper sizing is another critical factor. A plant designed for a family of four might not suffice for a household with six members. It's best to consult with suppliers or manufacturers to determine the appropriate capacity based on your specific needs.
Installing a sewage treatment plant should always be done by qualified professionals. This ensures compliance with regulations and minimizes risks to both users and the environment. During installation, factors like soil testing, pipework calculations, and electrical connections must be meticulously addressed.
Nutrient neutrality is another concern when installing sewage treatment plants. This refers to preventing increases in phosphate and nitrate levels in vulnerable watercourses, which could harm aquatic life. Following installation guidelines diligently helps prevent environmental damage.
Maintenance plays a pivotal role in keeping sewage treatment plants functioning correctly. Regular servicing, typically once a year, involves removing accumulated sludge and verifying bacterial levels. Protecting the system from excessive rainwater is equally important, as additional moisture can disrupt the biological processes.
