Drainage Services

Septic Tanks

We can help with septic tank maintenance and with installation work, as well as repairs and emergencies.

In a septic tank waste is allowed to settle, so that the liquid and solid waste separates. The liquid waste is allowed to flow out into a natural filtration system to ensure that it is not polluting the environment, the solid waste needs to be removed.


We can help with cesspit maintenance, clogging, leaks as well as repairs and installations.

Cesspits are used solely for the storage of sewage and do not drain off to a soakaway system, they are a sealed tank that has to be regularly emptied.

Sewage Treatment Plants

We can help with sewage treatment plant maintenance as well as repairs and installations.

Sewage treatment plants solve many drainage disposal problems when mains drains are not available and need not cost the earth.

Customer Reviews

Rob and the team were great, very friendly, professional and knowledgeable.

Excellent service, turned up when they said they would, completed when they said they would, would highly recommend.

Michael Clarke, December 2021

Rob and his team were very impressive from the first site meeting, understanding a difficult site and then spending the time on the project to ensure the job was completed in the way we wanted with the overall result being a very much improved system and this was achieved with the minimum of impact on our services.

Very highly recommended.

Jock Waugh, December 2021
Service delivered exactly as discussed and quoted. Highly recommended, many thanks.
Venus, July 2020
A thoroughly excellent experience. Rob was professional and courteous from the start, explaining the process and keeping us fully informed, listening to our ideas and questions while ensuring we understood what was possible and required. The process of installing a brand new tank was very smooth, the quality of his work excellent. Despite the appalling weather Rob and his team carried on working and finished the job, leaving the site in good condition. The cost of the job was competitive and good value for money. We have no hesitation in recommending Rob to anyone.
Ian, December 2019
Rob has been super helpful from the start and we’ve had a nightmare of a job to sort! Always picked up the phone when we called and nothing too much trouble. The actual work ran like clockwork and finished on time just like Rob promised. Highly recommended.
Michelle, November 2019
Rob gave us a trouble free installation from start to finish.
Work started on time and the guys got stuck in and managed to finish sooner than expected.
It is early days for us with this system but feel confident that if the company’s after sales service is as good as what we have had so far, we will be very happy.
Peter, November 2019

I contacted Bennett’s Septic Tanks Ltd with a view to installing a new sewage pumping station to solve a problem I was having with a defective septic tank. Robert the owner of the company came out to my house, discussed the best way to overcome the problem and gave me a no obligation quotation to install the pump station and the necessary pipe work and connections. The project started on time and was completed successfully to our great satisfaction within a working week. I am highly delighted with the level of service, quality of the workmanship and attention to detail provided by Bennett’s Septic Tanks LTD and would not hesitate to recommend the company to anyone who requires any drainage work carrying out.

Richard, September 2019

I have to say that Rob and his team provided outstanding service. He replied to our request promptly and came to survey the site and give us a price for the agreed work at the arranged time. The price quoted was competitive and there were no added charges even though the work was more complicated than first thought. The work was carried out to a high standard despite difficult weather conditions. He arranged for all the associated tasks, such as compliance with building regulations, to be carried out. In summary, a thoroughly professional company delivering a high level of service. I would highly recommend Bennetts Septic Tanks Ltd.

Rob, August 2019
