Pasco authorizes $407,540 change order for Process Water Reuse Facility Phase 2 well monitoring
Summary
The council approved Resolution No. 4598 to add up to $407,540 in change order funds to drill groundwater-monitoring wells as part of the PWRF Phase 2 winter storage improvements; staff said the total project is roughly $32 million and the wells are required for Ecology-approved land-application monitoring.
City staff told the Pasco City Council on May 5 that change order No. 9 to the Process Water Reuse Facility (PWRF) Phase 2 winter storage improvements project would add groundwater-monitoring wells to the nearly complete project. The council approved Resolution No. 4598 authorizing the interim city manager to execute a change order with Teppani Incorporated for a maximum amount of $407,540.
Staff said the overall project is about $32,000,000 and that the change order would raise the total contract to about $33,000,000. Ten wells were proposed: six located adjacent to the new ponds and four additional wells that may or may not be permitted by the Washington Department of Ecology; staff said the four uncertain wells could be removed later and, if so, the approved change order amount would be reduced.
The wells are intended to monitor groundwater quality at multiple depths to ensure land-application and storage operations do not negatively affect groundwater. A staff answer to council questions said deeper wells could reach about 300 feet while shallower monitoring points would sample near-surface water influenced by irrigation runoff. Staff said the facility plan is being approved by Ecology and hydrogeologic monitoring is required for land application.
Council member Milne moved to approve the resolution; it passed unanimously. Staff said the contractor’s price included no subcontractor markups and had been negotiated.
