Pressure Sewer Systems
In unsewered areas, semi-rural precincts, or topographically challenging terrain where gravity sewer is unfeasible, water authorities mandate Pressure Sewer Systems (PSS).
A pressure sewer system uses on-site grinder pump units at each property, pumping wastewater through small-diameter reticulation mains to the central treatment network.
Opal Water Management delivers specialised pressure sewer technical assessments, property boundary unit placement design, electrical compliance specification, and Sydney Water registration.
Opal Water Management possesses technical expertise in Sydney Water Pressure Sewer System standards, servicing both single-dwelling connections and multi-lot pressure sewer schemes.
