ABSTRACT:
A system consisting of multiple independent units each of which includes two standard fire hydrant connections located on two riser pipes and an interconnecting underground pipe providing a means for drafting tide, lake or river water from a streetside conneciton. Any pumper/tanker truck can thus connect a suction hose to the streetside riser and draft water through a second suction hose with one end connected to the riser at a bulkheaded waterside location and the other end equipped with a strainer is lowered into the water source. Standard lengths of fire hose suffice at both water and streetside connections when the water is bulkheaded and water level variations are sufficiently small that the lift capability of the pump is not exceeded. Pumping many begin when connections are complete. Backflushing with fresh water carried on the pumper/tanker may be performed if the pump is not well sealed and pumping begins after backflushing is complete and flow direction is reversed. Risers and connecting pipe are left full of fresh, potable, chlorinated water to eliminate marine or aquatic biological fouling and are capped when not in use. Additional biocide may be added to the system if necessary.
