What is a septic tank?

A septic tank receives and partially treats raw wastewater from properties not connected to municipal sewers.

With nominal capacities from 3,000 up to 250,000 litres, 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 discreet and reliable performance you can trust.

Please note: as a standard alone system, septic tanks that discharge to surface water no long comply with UK regulations (2020 General Binding Rules). However, our septic tanks are still extremely popular and can be installed as part of a larger sewage treatment system. 

 
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. Both scum and sludge require removal by a licenced waste carrier as and when required.

Partially clarified liquids accumulate between the layers of scum and sludge and exit the septic tank through a 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

After primary treatment, wastewater can be piped into an advanced secondary system for additional treatment (Ecoflo, MBBR, or SBR) or the tank can be periodically emptied by a professional.

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
