What is a septic tank?
A septic tank is an underground system that receives and partially treats raw wastewater from domestic or commercial properties not connected to municipal sewers. They are typically the most economical form of wastewater treatment.
With nominal capacities from 3,000 up to 250,000 litres, our Rewatec septic tanks (formally Conder septic tanks) are ideal for virtually any application. Quick to install, simple to use, and easy to maintain, these durable solutions give you a discreet and reliable performance you can trust.
Our septic tanks are also CE and UKCA marked having been fully tested and certified to EN12566-1.
Example applications
- primary residences
- seasonal residences
- residential developments
- apartment buildings
- campsites and parks
- office buildings
- commercial sites
- schools
How do our septic tanks work?
Primary treatment
Wastewater from the property runs into a main drainage pipe that flows into the septic tank. The septic tank’s job is simple: it allows wastewater to separate into three layers.
In the top layer, oils, greases, and fats float to the surface and form scum. In the bottom layer, solids settle on the bottom of the tank and form sludge. Periodic emptying by a licenced waste disposal company is required to remove the gradual build-up of scum and sludge.
Partially clarified liquids accumulate between the layers of scum and sludge and exit the septic system through the outlet pipe. An integrated effluent filter - standard in all 3,000-10,000 litre polyethylene Rewatec septic tanks, capture suspended solids that could clog system components further downstream.
Wastewater final dispersal
As the effluent is not fully treated, wastewater can flow into an advanced secondary system for additional treatment (Ecoflo, MBBR, or SBR) to meet the the general binding rules set out by the Environment Agency and to fully protect our environment.
Septic tank maintenance
Protect your investment in your Rewatec septic tank by having it regularly inspected and desludged by a qualified service professional.
The frequency of service depends on the size of your tank, the amount of wastewater your property generates, and the environmental regulations in your area. It is best to speak with a local service professional to determine the service schedule that is right for you.
When your service provider visits your property to inspect your system, they should:
- check for cracks and leaks in the tank
- measure the scum and sludge layers
- desludge the septic tank as required
- clean the effluent filter in the outlet pipe
- keep and update maintenance records for your system
- explain any areas of concern and recommend next steps
