Pressurised Sewers
Pressurised sewers, or pressure sewers differ form conventional gravity collection systems, because they break down large solids in a grinder pumping station before they are transported through the collection system. The pressure sewer system consist of a series of centrifugal grinder pumps moving finely ground effluent and material along a network of sewers (generally small-diameter). The primary effluent is delivered to the dwelling tank by traditional gravity drainage methods before being ground.
