Septic Tanks in Northamptonshire and the Surrounding Counties


Septic tanks are designed to handle daily effluent flowing from a household. They vary in size and capacity. A typical septic tank has a volume of 750 to 1500 gallons and it may be made from concrete, bricks or fibreglass. Normally they are about 6-8 feet deep and 6 feet wide. They are watertight and this promotes the growth of anaerobic bacteria & biological decomposition of sewage and waste water.

Unlike Cesspits, Septic Tanks allow liquids to flow through the tank and out into surrounding land via a soak away this system does not cause damage to the environment.

Septic Tanks need to be emptied on a regular basis. As a rule of thumb most domestic properties tanks should be emptied every 12 months however the frequency of emptying depends on the size of the property and the number of people using the water system, to avoid damage to the soak away and waste water backing up to the property.


Cesspits/pools come in various sizes and they simply store the waste and obviously have to be emptied when full. They are usually underground and their location is identified with a single manhole cover.

The frequency of emptying will depend on the size of the tank and the amount going in.

Treatment Plants

A treatment plant is a mechanical system that treats your sewage from your property and the final effluent is discharged into a soakaway or into the water course close to your property. The sludge remains in the plant and must be removed on a regular basis on average once per year from a normal domestic property. As with septic tanks, the frequency of emptying will depend on the property size and number of occupants.

To discharge into the water course you will need a Licence from the Environment Agency. For further information please click on the Environment Link on our home page.

Pump Chamber

Pump Chambers are exactly as their title suggests, with effluent from your property flowing into the chamber where it is pumped away usually to the mains or to a soak away on higher ground than the property.

It is essential that pump chambers are regularly emptied and washed down and any fat and rag is removed so as the pumps do not get clogged and burn out due to jamming of the impeller. It is also advisable that pumps are regularly checked by a service engineer to avoid breakdown and a resulting sewage backup to the property.

Mobile Toilets

Kitchen Grease Traps

Grease traps are mostly found in pubs, hotels & catering establishments. A grease trap is normally installed to catch food waste and fat produced by the kitchen. It is important to regularly empty grease traps and wash them down so as to prevent blockages in your drainage system.

Mobile Toilets

We are fully conversant with the emptying of mobile toilets, large or small, and also have water lances on our vehicles, enabling us to wash and clean down all mobile toilet units. This leaves them ready to go to another venue.

Interceptors & Tank Bunds

We are able to empty a large number of these. However, most of these are categorised as hazardous waste and as a registered waste carrier the Environment Agency will require correct documentation confirming that the waste is disposed of at the correct facility. We can provide the correct Duty of Care documentation.

Recommended Technicians

We have recommended suppliers who are experienced in all aspects of sewage management and treatment. They have worked alongside us for many years.
