This is a service / maintenance or supply contract in Grandview, Washington. Contact the soliciting agency for additional information.

Furnish all materials, equipment, and incidentals required for supply of a complete aquifer storage and recovery (ASR) well downhole control valve, including valve design, controls, delivery, and startup assistance. The ASR valve is used to alternately control the recharge flow rate into a well or allow a submersible pump to pump water to the surface. The valve is to be placed above the submersible pump and motor to control recharge flow rate and water levels in the ASR well, and allow pumping to the surface. A check valve (not supplied by ASR valve manufacturer) will be placed between the ASR valve and the submersible pump and motor to prevent recharge water from going through the pump in reverse flow. The valve must be designed to eliminate cavitation and aeration in the column pipe and through the ASR valve during recharge at the specified conditions and must keep the pump column pipe full. The valve must be capable of infinitely controlling the injection flow rate from 0 gpm to the maximum specified injection rate. The Owner and/or the Owner’s installation contractor will be responsible for unloading and installing the equipment provided under this section according to the instructions and recommendations of the equipment manufacturer. Bidders must submit sealed bids for manufacture of the ASR well control valve on a unit price basis, with bids accompanied by a bid security of at least 5% of the bid amount. The District reserves the right to reject any or all bids and to waive any irregularities as informalities.
