A septic tank is designed to provide what is known as primary treatment to crude wastewater produced in a normal domestic environment. It retains solids and allows them to settle out, where they can be partially broken down by biological action so that only the remaining liquor is left to flow down the outlet drain. This liquor (normally called effluent) is then sufficiently treated to soak into the ground in an underground soakaway system.

• BBA Accredited (Cert. no. 94/3021)
Balmoral septic tanks are designed in accordance with British Standard Code of Practice BS6297 and are based on a two chamber design with a long flow path which ensures a high degree of settlement and sedimentation, thus providing a low level of suspended solids suitable for discharge into an underground soakaway system.
