SPA 2 Regional WRF Phase 1 - 2 MGD

Project Overview

The City of Surprise retained PCL for Construction Manager at Risk services for a 2.0 MGD Membrane Water Reclamation Facility in the City’s Special Planning Area 2 (SPA 2). The facility incorporated biological nutrient removal, membrane filtration, and UV disinfection. The City challenged PCL and the design engineer to produce a water reclamation facility for SPA 2 that could produce Class A+ reclaimed water—the highest quality reclaimed water in Arizona— within a well-defined budget for design and construction. To meet this challenge, the design engineer developed a conceptual design for a facility that utilized common wall construction and a membrane bioreactor. The use of common wall construction allowed efficient use of the site area, minimizing excavation and backfill to allow future expansion. The use of a membrane bioreactor eliminated the need for conventional sedimentation, filtration, and disinfection facilities, thus minimizing excavation, concrete, and electrical construction costs. This overall approach allowed for facilities to be constructed in close proximity to each other, thereby reducing yard piping, electrical conduit, and site work. Reclaimed water disposal went through on-site vadose zone recharge wells.
