The South Adams County Water & Sanitation District recently constructed and tested an innovative high-capacity non-conventional Horizontal Collector Well (“HCW”) in the South Platte Alluvial Aquifer, adjacent to the South Platte River.  In Colorado this HCW is the first documented design of its kind, and yielded the highest documented pumping rate from a single well. Testing has shown that this HCW is capable of producing over 6,000 gpm for long-term pumping, and up to 9,000 gpm (13 MGD) in the short term.  This talk will focus on the design, construction, and testing of this HCW, and also will focus on the hydrologic conditions suitable for a HCW and the economic considerations that make a HCW advantageous over a battery of conventional wells or a surface water diversion. Quantifying delayed HCW pumping depletions to the river also will be discussed.
