Permissions Required for Sewage Treatment Plants

permits to dischargeBy the 1st January, 2012, ALL discharges from septic tanks and sewage treatment plants will have to be registered with the Environment Agency.  This applies to both new and existing systems, no matter how old they are.

Until recently, anyone who had a sewage treatment plant or septic tank that discharged either to the ground or a watercourse, needed to have a Consent to Discharge from the Environment Agency.

These rules changed on the 6th April 2010. The Consent to Discharge has been replaced by a Permit to Discharge under the Environmental Permitting Programme Second Phase.

However, as all sewage treatment plants now for sale must have been tested and hold the EN 12566-03 Certificate, an Exemption scheme has been introduced, as these plants should not pose a pollution problem if properly used and maintained. You can now register for an exemption online or via a form from a Permit to Discharge for:

  1. Sewage Treatment Plants discharging up to 5m3 per day or less into surface water (27 population equivalent)
  2. Septic Tanks / Sewage Treatment Plants discharging up to 2m3 per day or less into groundwater (11 population equivalent)

Please note that for approved treatment plants, such as those we recommend from Marsh Industries, there is no fee for the registration of an exemption.

Further information on how to register your septic tank or treatment plant is available on the Environment Agency Website.
