Septic tank and cesspit

The purpose of a septic tank is to treat waste water from premises generally not connected to the mains drainage system.  Waste material (sludge) is allowed to settle in the tank and is digested by natural bacteria which must be allowed to breed within the tank.  Over time this sludge builds up on the bottom of the tank.  This sludge has to be removed regularly to ensure that the tank continues to work properly and to prevent the soakaway becoming chocked.  

If you are an owner/user of a private septic tank, the quality of the discharge and its impact on the environment are your responsibility.

Emptying should normally take place every 12 months.  However, depending on the tank's size and usage, this period may be extended, but is not normally beyond two years.

We do not provide this service, however there are a number of companies offering services related to septic tanks and cesspits in the district. Please see the local telephone directory for details.

However, if someone else's Septic tank or cesspit is causing a nuisance, please contact Environmental Health.
