The following Environment guidance note provides comprehensive and up to date legal information covering:
Septic tanks and small sewage treatment plants are wastewater systems for domestic sewage that are used when properties are not connected to the mains sewage network.
Homes and businesses must connect to a public sewer if they are located within 30 metres of the mains sewer, or the equivalent distance for a development of more than one property (eg 90 metres from a public sewer is there is a development of three properties).
Domestic sewage includes wastes arising from normal domestic activities wherever carried out, including from:
Sewage discharge can cause river pollution, damage habitats and contaminate drinking water supplies. Exposure to sewage can also impact health and lead to nuisance complaints between neighbours.
Unless sewage discharges are exempt, operators of septic tanks and sewage treatment plants must obtain an environmental permit under the Environmental Permitting (England and Wales) Regulations 2016 (EPR 2016), SI 2016/1154.
An operator includes:
the property owner using the system
the property owner sharing the system with other properties—each property owner is an operator, and is jointly responsible for complying with the general binding rules
an entity that has a written agreement with the property owner that says they are responsible for the system’s maintenance, for example a tenancy agreement
