The new Bay 101 casino required 6 stormwater pump stations to handle low flows of stormwater in San Jose, California. Each pump station will help serve new hotels as this casino facility expands. These pump stations needed to meet the low flow requirements while maintaining consistent head conditions.
The revitalization of a large mall in Santa Clara, CA required a new pump station to handle low flows of stormwater runoff from a section of the parking lot. This system utilized an economic design with a 4-foot ID precast concrete wet well, schedule 80 PVC discharge piping, and small ½ hp Weil pumps in a duplex configuration.
This was a true lift station replacement by installing a new package lift station “in the hole” of the removed wet well. Submersible pumps in a duplex configuration were included to meet the low sewage flows from the federal training facility. The system valves were installed in the discharge piping inside the wet well to reduce cost and simplify the system. An outdoor alternator panel handles the controls for this package lift station. It was designed with floats for liquid level sensing and a basic alarm.
The construction of a new gas station and convenience store required this low flow sewage lift station. Goulds submersible grinder pumps in a duplex configuration are designed to macerate and pump wastewater that contains solids or fabric materials without becoming clogged. The complete valve assembly is vertically oriented and contained within the wet well discharge piping. An outdoor UL listed control panel contains an intrinsically safe barrier for in-well electrical, floats for level-sensing controls, and a NEMA 4X stainless steel enclosure.
This wastewater lift station was required to hand medium sewage flows from a development neighborhood by Smith River Rancheria, the governing body of the Tolowa Dee-ni’ Tribe. Two Goulds Water Technology 2 hp grinder pumps were used to meet the high head requirements for over 3,000 ft of force main. A owner-supplied control building contains the control panel and an permanent onsite Cummins generator for backup power. A Mercoid pressure transducer provides primary level-sensing controls with Dwyer floats for backup.
