ABSTRACT:
Apparatus and methods use a portable submersible pump to mix and fluidize waste material (sludge, liquid and floating crust) in a septic tank, to then pump it into a truck-mounted holding tank to recirculate it in the holding tank during transport, and to discharge it at a disposal site. The apparatus comprises a truck-mounted holding tank having tank inlet and outlet ports, a portable hydraulically driven submersible pump detachably mounted on the truck, and a truck-mounted motor-driven hydraulic pump for operating the portable pump. Hydraulic fluid supply lines, wound on a truck-mounted reel, are connected between the hydraulic pump and the portable pump motor. A waste hose is wound on a truck-mounted reel, several hose sections are detachably mounted on the truck, and a portable, multi-position, manually-operable selector valve is detachably mounted on the truck. In operation, the portable pump is disposed alongside or in the septic tank and pumps a stream of pressurized fluid from the septic tank. Various combinations enable the stream to be pumped directly into the truck-mounted holding tank, or to be mixed and recirculated in the septic tank prior to being pumped into the holding tank. After the components are stowed, they can be used to recirculate the mixture in the truck-mounted holding tank during transport and/or to empty the latter.
