1.0 General Information.

1.1 Overview. The USAG-RP sanitary wastewater treatment and collection system collects and discharges sanitary wastewater as well as storm water to the public sewage system. There are approximately 145km of sewer mains ranging from DN100 to DN1500 in diameter, and approximately 4000 manholes. There are 29 sewage lift stations and 27 septic tanks throughout the Garrison. See corresponding TEs for Details.

1.2 Components. Sanitary wastewater and storm water treatment and collection system components include, but are not limited to: elements included in ISO DIN EN 12 056, DIN 1986-100, DIN EN 752, DIN EN 1610, ATV A127/139/142 and related standards. E.g. all kinds of collection lines, shafts, manholes, pumping and lifting stations, separators POL and grease/starch, retention basins, ditches, culverts, sinks, sludge traps, septic tanks, settlement tanks, portable water closets, /*wash racks and /*wash stands, mechanical and electrical flow control valves as well as mechanical and electronical metering and control systems. /*Wash racks are composed of a structure/building with high-pressure water system to externally wash vehicles and a holding basin with oil/grease separating system and water recycling capability. /*Washstands are hard stands with oil/grease separators and water hose hook-up for vehicle washing.
