Award recognized work on Surprise South Water Reclamation Plant Vadose Zone Recharge System

The Arizona Water Assn. (AZ Water) presented the 2010 Water Reuse Project of the Year Award to Lockwood, Andrews & Newnam, Inc., (LAN) and the city of Surprise, Ariz.

The award, presented during the 83rd AZ Water Assn. Annual Conference in Glendale, Ariz., recognized the project team’s work on the Surprise South Water Reclamation Plant (SSWRP) Vadose Zone Recharge System. All project team members, including the owner (city of Surprise), prime consultant (LAN) and team of sub-consultants, and the prime contractor, received individual plaques.

“The city of Surprise is honored to receive this award from a great organization like AZ Water, and this truly shows how teamwork between consultants and the City can produce a very successful project,” said James P. Shano, utilities capital improvements plan manager with the city of Surprise.

Since 2003, Project of the Year awards have been presented on an annual basis to recognize outstanding engineering excellence and achievement in the water, wastewater and water reuse categories. Projects are judged based on several criteria, including original or innovative application of new or existing techniques, social and economic considerations, meeting and exceeding owner needs and complexity. The water reuse category was added in 2006.

The SSWRP Vadose Recharge System was developed by the design team of LAN, HydroSytems, Inc., and DLT&V Systems Engineering, Inc., as part of the city of Surprise’s master plan to expand the SSWRP wastewater treatment capacity from 7.2 million gal per day (mgd) to 16.3 mgd. To store the plant’s increased volume of reclaimed water underground, 52 site-specific vadose recharge wells have been master planned for installation in multiple phases at two different locations in the city service area. Other project elements in this recharge system include associated delivery pipelines, booster pump station modifications, geo-membrane reservoir cover and a SCADA control system.

To date, five initial vadose zone recharge wells and associated facilities have been installed at the SSWRP site. In addition to the recharge well system, the associated infrastructure, consisting of 4,700 linear ft of 20-in. pipeline, well delivery manifold, a floating reservoir cover and pressure control stations to recharge an estimated 2.2 mgd of Class A+ reclaimed water, was constructed. LAN provided project management, planning, civil engineering and construction management services for the project.

“The award is a testament to the project’s contribution to our community and recognition of the value we bring to our clients,” said LAN project manager, Floyd L. Marsh. Marsh is the water resources manager and practice leader for the Phoenix office of LAN.
