PHOENIX — The Arizona Water Association (AZ Water) presented its 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 Association Annual Conference in May, recognized the project team’s work on the Surprise South Water Reclamation Plant (SSWRP) Vadose Zone Recharge System. 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 gallons a 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 locations in the city service area. Other project elements in this recharge system include associated delivery pipelines, booster pump station modifications, geomembrane 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 feet of 20-inch 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.

Water and transportation among topics at EngEx 2010
SAN DIEGO — Conference organizers expect an estimated 10,000 professionals in the energy, water, transportation, and environmental industries to attend EngEx 2010, July 29-31, 2010, at the San Diego Convention Center. Among the topics planned for the conference are renewable energy, the electric grid, desalination, wastewater treatment, fuel infrastructure, sustainable planning, carbon storage, and carbon reuse technologies. The conference also features keynote addresses by national green technology leaders, information on grant opportunities, and a career and internship fair.

“EngEx 2010 will be a showcase of the latest research and development of green technologies,” said Kris Ellis, vice president of operations with EngEx 2010. “However, it will also be an opportunity for corporations and government agencies to present their technologies, policies, and strategies to a large public audience.”
