ABSTRACT:
Sludge collection and removal systems are disclosed. The present invention provides methods and apparatus that include piping system of headers and laterals selectively provided with flow from a central point so that sludge can be removed from areas where it accumulates most rapidly. The adaptable nature of the piping system additionally permits the number of collection laterals and orifices to be varied to suit the sludge accumulation characteristics of the sludge basin. Additionally, improved multiple port valves are disclosed that permit the selective connection of the flow among sections in preferred embodiments of the sludge collection systems.
