Our Sewage Waste Water Treatment Services

Septic Tank Cleaning

Regular cleaning extends the lifespan of your septic system. By sticking to a routine cleaning schedule, you reduce the need for costly repairs and replacements. The accumulation of sludge and scum is kept in check, which means fewer mechanical failures and a longer-lasting system.

Septic Tank Cleaning

Septic Tank Emptying

When a tank gets too full, it can't properly filter the waste, leading to blockages and backups. These failures often result in extensive and costly repairs, which can easily be avoided with timely emptying of your septic tank.

Sewage Treatment Plants

A modern replacement to septic tanks, sewage treatment plants are much cleaner and environmentally friendly. They can separate liquid and solid waste, reducing their impact on the local environment.

General Binding Rules

All old tanks that discharge into surface water must be upgraded or undergo a septic tank conversion by 1st January 2020 or when the property is sold. Septic tanks that discharge into the ground are exempt from this requirement but must still comply with the general binding rules.

Very responsive and professional. Mark took the time and care to explain everything to me, and gave the system a thorough inspection - the world of treatment plants was completely new to me!

Having researched companies to install a sewage treatment plant for my house, I chose Cotswold Drainage. I have not been disappointed at any stage of the process. From the outset, communication has been exemplary, every person I met, in person or on the telephone, has been very polite, and took time to listen and answer our questions. The quality of the work done has been, to my untrained eye, of a very high standard. Disruption has been kept to a minimum and the area has been left very tidy, now waiting for grass seed to sprout! I had some further pipe work done separately from the septic tank installation, and again, it was a very straightforward process with minimal disruption. Well done Stuart and all at Cotswold Drainage. Many thanks.
