gtag('config', 'UA-65464427-1'); Interceptors and Separators

Interceptors or separators are used where there is a risk of oil, chemicals or suspended solids contaminating the surface water drains. They are designed to remove pollutants from the water and allow the cleaned water to discharge into a surface water drain.

Bypass separators are used in low risk sites such as a car park. Full retention separators are used on sites where there is a high risk of contamination. Both types come in two classes:

Class 1
Achieves concentration of 5mg/l of oil and can be discharged to surface water drain.

Class 2
Achieves concentration of 100mg/l of oil and can be discharged to foul sewer.


Our interceptors and separators are compatible with these types of sewage treatment systems
