Solids Dewatering Facility
Submitted by MMC, Inc
This facility at the Clark County Water Reclamation District’s Central Advanced Wastewater Treatment Plant, is designed to be completely automated and self-sufficient, running 24 hours a day, 365 days a year.
Construction included solids pumping, transmission and dewatering facilities. Features include two huge storage tanks for primary and thickened waste-activated sludge, feed pumps, eight centrifuges capable of producing 575 tons of dewatered cake daily and a cake conveyance system. Most of this is contained inside a very complex, multi-story building with a contemporary architectural fa�ade to blend in with the surrounding area.
The fully-automated cake loading system is the first of its kind to be implemented in North America. One ironic construction hurdle involved the dewatering facility’s site, which itself had to be de-watered before piping was laid, due to poor soil and shallow water table.
