We are a safe, considerate and trusted sewage treatment specialist. We supply, install and service sewage treatment plants, septic tanks, cesspools and pump stations. We also offer other services such as CCTV drain surveys, drain jetting and percolation and porosity tests.

Trading for over 25 years, we are a family-owned business that has grown rapidly in recent years due to our commitment to exceptional customer service. We believe in good old-fashioned values like honesty, attention to detail, professionalism and delivering a job well done. These values, combined with a proven track record of completing projects on time, to the highest standard, safely and within budget, is why our customers re-use us time and time again.

At Cotterill Environmental, we also embrace innovation and have a forward-thinking approach that enables us to use the latest technologies and equipment. Our clients range from large blue-chip building contractors to domestic households.

​We're extremely proud of the work that we do. We care about making a positive impact on the environment and the communities we serve through the projects we deliver.

Our Social Responsibility

We want to make a positive impact on the communities we serve and core to this is our Social Responsibility Strategy.

This is something we feel passionate about and regularly undertake initiatives in line with this, along with our sister brands, Cotterill Contractors and Cotterill Drainage. These range from delivering donations to local food banks to showing our support to the NHS to holding or supporting charity events.
