It is cleaz from reading the Colorado Water Well Construction Rules that this Arequa Gulch pumpback Sump and drains do not meet design standards for a typical water well. As mentioned in our initial application dated July 2006, CC&V is currently augmenting for waters captured in the pumpback system as pazt of the approved CC&V Substitute Water Supply Plan (SWSP). Condition #2 of the approved SWSP re wires that CC&V obtain a water well permit for the pumpback system. The Arequa pumpback System consists of the following features: • Horizontal perforated drains to collect shallow ground water beneath the CC&V Valley Leach Facility (VLF). These drains are connected to the concrete collection vault. • A pipe connected to a shallow spring beneath the VLF connected to the concrete collection vault. • An engineered and sealed concrete collection vault and building. • Pumps and piping to direct water collected in the vault to the VLF make-up water circuit. I have enclosed additional design details regazding the pumpback system along with a narrative description of the system that was provided to Colorado Department of Public Health and Environment (CDPHE) in 2003.
