The major Project elements consist of, but are not limited to, the following items: • A pump station with variable frequency turbine pumps and capacity ranging from 15 CFS (2.6 MGD) to 100 CFS (64 MGD) to be located on the northeast slope of the South Reservoir. The pump station structure consists of a reinforced concrete wet well and masonry electrical control and pump station buildings. • Inlet/outlet structure on west bank of the River. • Inlet/outlet river pipeline from the wet well to the South Platte River. • Inlet/outlet on the southeast bank of the Central Reservoir. • Inlet/outlet reservoir pipeline from the wet well to the Central Reservoir inlet/outlet structure. • Site-wide fence improvements. • Site-wide road improvements. • Installation of SCADA communications and water control equipment automated controls. • Coordination with Power Utility Company. • Coordination with Metro Sewer during installation of Metro new sewer lines adjacent to, and concurrent with, Pump Station Construction. • Coordination with City Contractor during rip-rap installations and spillway reconstruction to be performed by others. • Coordination with UDFCD for access to river and future improvements to river bank and rip-rap protection. • Coordination and access sharing with existing gas and oil facilities adjacent to the proposed pump Station. The preliminary construction cost estimate is approximately six to seven million dollars ($6,000,000 to $7,000,000).
