Stem Drive has won a contract from the Trident North Alliance for its patented, nonblocking, wet well mixing system for maintaining solids in suspension at Hallingbury Road Pumping Station, Bishops Stortford, based on actual tests to mix floating solids with sewage carried out by Trident North for Thames Water The project objective is to eliminate excessive rag build up which requires expensive cleaning operations to remove

The raft of rag forms on the surface of the sewage, which is not transferred by the pumps.

Mixing is required to maintain the rag in suspension to allow removal by sewage pumps on a regular basis.
