低压下水道 (LPS)

LPS consists of grinder pumps, basins, piping, valves and controls creating a method to grind and pressure residential and municipal sewage through small diameter pipe following the contour of topography maintaining a depth below frost levels to a WWTP, or Lift Station, or gravity sewage line.  The collection system connects all grinder pump stations to a common force main. These systems are isolated with curb-stops consisting of curb-stops, flushing connections and air release valves.
