Installing a sewage treatment plant is a common requirement for UK homeowners who are not connected to mains drainage. However, properties located near streams, rivers, or other watercourses often raise an important question. Can a sewage treatment plant be installed safely and legally near water?
The answer is yes, in certain circumstances. That said, strict rules apply. These rules exist to protect the environment, public health, and local water quality. In this guide, we explain the regulations, typical guidance, and practical considerations in clear and straightforward terms.
Get in Touch TodayA sewage treatment plant is a modern system designed to treat household waste water before releasing it back into the environment. Unlike septic tanks, which rely largely on settlement, sewage treatment plants use biological processes to clean waste water to a much higher standard.
Once treatment is complete, the clean effluent is discharged either into a drainage field through a soakaway installation or directly into a nearby watercourse. The discharge method plays a major role in determining whether installation near water is permitted.

This is important because waste water discharge near any watercourse is regulated to prevent pollution and environmental harm.
Book in TodayYes, a sewage treatment plant can be installed near a stream or watercourse, provided it complies with environmental regulations. In England, these requirements are set out by the Environment Agency under the General Binding Rules.
These rules apply to both new installations and replacement systems. However, replacement systems may be assessed slightly differently, depending on whether they are causing pollution.
Call us TodayWhere treated waste water is discharged to ground, correct soakaway installation is critical. The soakaway must suit the soil type and groundwater conditions.
Percolation testing is usually required to confirm that the ground can absorb treated waste water safely. Poorly designed soakaways are one of the most common causes of system failure.
In areas close to watercourses, a surface water discharge is often the preferred solution, provided the system meets the required standards.

Many systems operate under the General Binding Rules. However, some installations require an environmental permit.
If it is not causing pollution, it may be allowed to remain. If pollution is present, corrective action will be required.
