The longest rehabilitated pipeline in Arizona history.

Dibble provided assessment, design, and construction administration services for the City of Peoria Beardsley Wastewater Reclamation Facility’s 8-inch diameter ductile iron pipe waste activated sludge force main. Dibble assessed the condition of 13,900 linear feet of force main by extracting samples from the force main and conducting various tests, which included wall thickness, stray current, soil corrosivity, chemical spectroscopy, and metallurgical. Dibble determined that the force main was in various stages of deterioration and provided design options for rehabilitation, using a sliplining technology. Several sliplining products were considered, but fusible polyvinyl chloride (FPVC) pipe was recommended base on the length of installation and cost.

Dibble provided design drawings depicting access pit locations, installation lengths, and the preliminary bypass plan. Construction administration and inspection services included shop drawing submittals, requests for information (RFIs), and on-site inspection of work. The project provided a cost-effective solution for a nitrate removal system, storage, and booster pump station to provide flow and maintain pressure to the distribution system.

This project was awarded the 2020 AZ Water Association Project of the Year Award and the 2020 APWA Arizona Public Works Project of the Year – Less than $5 Million Award.
