Treatment Plants and Waste Treatment Services

ASL Ltd have special expertise and experience in dealing with the treatment of waste, where there is no connection to main sewers.

In our opinion, many existing tanks are possibly polluting, and have not been modernised to serve a large property. They are often also quite dated and have not been upgraded. They would not pass current legislation.

“The system will have difficulty coping with modern living i.e. with the use of washing machines, dishwashers and other kitchen appliances, along with contemporary standards of personal hygiene, which include daily bathing for many. Older tanks can lack the capacity or capability required for modern living, even if adequate when they were installed. When surges of water enter the tank, such as when a bath or washing machine is emptied, because there is no separation in the tank, sewage and sewage water will get stirred up, allowing solids and fats in suspension, to be flushed through the system and into the soakaways, where they will cause irreparable damage.” (Environment Agency).

Cess Pits

The minimum requirement as per building regulations is 4,000 gallons.

Although you are allowed to have a cesspit, it’s not recommended as it is containment only, and needs to be emptied every 8-13 weeks. It can be a shorter or longer period depending on usage.

In the future when you sell your house, a cess pit, in our professional opinion, will de-value the property by probably £20,000. In our experience, buyers avoid houses with cesspits because of high maintenance costs.

Our charge to carry out the installation of a cesspit is currently around £9,000.00 plus VAT, subject to the soil’s suitability. The price does not include de-watering and sheet piling, if it were necessary.

One of the most important decisions is the choice of the right sewage disposal system for your home, or particular site. The choice of solutions is quite varied, and there are many factors to be taken into account, including current legislation and any potential environmental impact.

We believe that the supply and installation of one of our treatment plants would provide the best long term solution. We have found our treatment plants to be robust and very reliable in use. The treatment plant has the advantage of very few moving parts, so there is less to go wrong mechanically, and they only require emptying down annually, rather than every 4 – 6 months, so this much more convenient, and cost effective.

At ASL Ltd, we use only the best products: Titan, Klargester & Balmoral tanks. We make sure that the particular installation which is chosen is the correct choice for your particular site.

If you have a new or old property and mains drainage (foul or storm water) is possibly available then it is likely that you will require a sewer connection survey or investigation. As most sewers are often in the public highway, any excavation will then come under The New Roads and Street Works Act 1991.

ASL Limited are accredited contractors and we can apply on your behalf to obtain a road opening permit. All the documentation will be carried out by are friendly office staff and we will arrange all necessary inspections.

Main Foul and Storm Sewers

Sewer connections do require initial planning and we would be pleased to offer our advice for your project. We will submit plans on your behalf once we have carried out a survey and search.
