Gosport Off Mains Drainage FAQ
In order for wastewater to be taken away from your property, it will be connected either to a network of pipes leading to a main sewer, or to its own private drainage system, also known as off mains drainage. These properties are typically situated in more rural locations where a connection to a main sewer is not possible.
Your sewage treatment plant has to be 5 metres away from trees, fences and hedges, 10 metres away from a watercourse or stream, and 50 metres away from any lake or foreshore. Last but not least, it has to be 7 metres away from your housing and 4 metres away from a wall or a building.
Areas we serve include: West Sussex, East Sussex, Hampshire, the New Forest, Surrey, Kent, Berkshire and parts of Wiltshire and Dorset. If you are unsure whether we cover your area, please contact us and we’ll be happy to advise.
There are three different types of tanks:
- Septic Tanks
- Cesspits
- Sewage Treatment Plants
Septic tank:
A septic tank does not have any mechanical parts, and it doesn’t perform any ‘treatment’ of the waste. Instead, the waste enters the tank from the property, then separates into three different layers. The middle layer of separated waste water then leaves the tank, typically into a soakaway system.
A soakaway system is typically a network of slotted or perforated pipes, which allow the waste water to percolate through the sub soils without causing a pollution.
The remaining contents of the tank are then removed at regular intervals by a tank emptying company.
Cesspit:
A cesspit is literally just a holding tank for the waste from your property. Waste goes in and stays there until the tank is emptied. There is no treatment of the waste that goes in. A cesspit will need emptying on a regular basis.
Sewage Treatment Plant:
A sewage treatment plant is the most modern form of off mains drainage tank.
Powered by an electricity supply, a sewage treatment plant provides treatment of the waste. This means that the waste water that leaves the tank is cleaner than that which would come from a septic tank. For this reason, it is allowed for a sewage treatment plant to discharge straight to a ditch or watercourse. An STP will also require emptying, but not as regularly as a cesspit.
Septic Tank: approx. every 3 years.
Cesspit: between every 6 weeks to every 12 months, depending on usage.
Sewage Treatment Plant: approx. once every 12 -18 months.

No, all will need emptying at some point.
If you’re installing a new septic tank in a domestic or commercial property, you will need planning permission from your local authority. If you’re simply replacing an old one, however, there’s no need to seek further permission.
