C-2.2. Utilities: The Contractor is responsible for locating all utilities prior to beginning work.

C-2.2. New Well: The Contractor shall drill a new 6 inch PVC well within 15 feet of the old well on the west northwest side of the pump house in the lawn. The pump house has 3-phase electricity available. The contractor will be required to add a main electrical panel, breakers, wiring, conduit, parts, Etc. to power the new well and components with 3-phase electricity. The well pump for the new well shall be variable speed, 3-phase, minimum 7.5HP at 75GPM or larger depending on well capacity after the well is drilled and sized appropriately to be compatible with the new fire hydrant as specified in paragraph C-2.4, plus supply the demand for the Leech Lake Recreation Area that may utilize up to 4,000 thousand gallons of water per day during the months of May thru October and as little as only about 1000 gallons per month during November thru April.

Contractors are to bid this work to comply with minimum 7.5 HP at 75 GPM. Once the new well is drilled, the new well capacity will be determined by the contractor and that data must be provided to the US Army Corps of Engineers along with actual HP and GPM recommendations along with pricing information for appropriately sized equipment that matches the new well capacity for consideration by the Contracting Officer or Representative to modify the pump, piping sizes, from the above specified 7.5HP at 75 GPM, etc. Then the contractor shall provide and install an appropriate well regulator/control box and pressure switch, appropriately sized rigid water line down the well, appropriately sized poly water line from the new well into the pump house, appropriately sized stainless steel well screen, new wiring from the well to the new regulator/controls inside the pump house, and a replacement pressure tank to accommodate the new variable speed pump system.
