Neely WRP Operational Assessment* | Town of Gilbert, AZ | Gilbert, AZ | Project Manager

BC performed a plant-wide assessment of all critical treatment process, electrical, building mechanical, and structural assets of the Neely WRP. The plant is operated under a contract with Severn Trent Services (STS), whose contract was due to expire in the coming year. Gilbert desired an assessment of STS’s performance to determine whether the operating contract would be renewed, re-advertised, or whether Gilbert would assume operation of the plant. This plant includes influent pump station, screening, grit removal, oxidation ditches with separate anoxic basins, secondary clarifiers, sand filters, and chloride disinfection to produce Class A+ recycled water for irrigation and aquifer recharge. Solids are returned to the sewer.

Our assessment of this 11 mgd plant was conducted using the Water Environment Research Foundation (WERF) Asset Management Approach and Guidelines. This study resulted in a prioritized capital improvements plan and verification of the maintenance activities performed by STS over the course of their operating contract. The resulting study allowed Gilbert to make decisions regarding the future of the operations of the Neely WRP.

Gainey Ranch Wastewater Treatment Plant Improvements and Recharge* | City of Scottsdale AZ | Scottsdale, AZ | Project Engineer

Designed improvements to a 1.7 mgd plant that treats reclaimed water for irrigation of the golf course and other landscaped areas at Gainey Ranch, a sensitive, high profile residential area. The scope of the project rehabilitated processes that were in disrepair, upgraded the secondary treatment capabilities to permit NdeN/BNR, evaluated the process for possible capacity expansion, and upgraded all processes necessary to meet anticipated regulatory requirements. The improvements include new preliminary screening facilities, modifications to the bioreactors, clarifier equipment replacement, new ultraviolet disinfection facilities, and tablet hypochlorite systems to replace gaseous chlorine. The bioreactor modifications allow the plant to reduce effluent nitrogen levels to below 8 mg/l and effluent phosphorus levels to less than 1 mg/l. The improvements are configured to streamline attainment of the permit requirements for the new effluent reuse regulations and aquifer protection permits. (Damon S.

INDUSTRIAL WATER AND WASTEWATER

Membrane Bioreactor System Evaluation* | Hilmar Cheese | Hilmar, CA | Membrane System Specialist

Rob led the investigation and evaluation of suitable membrane bioreactor (MBR) systems and selection of systems for pilot study of this high-strength cheese manufacturing wastewater facility. The evaluation consisted of identification of membrane manufacturers and membrane bioreactor suppliers worldwide, then screened to those doing business in the United States. Four candidate MBR systems were selected for further evaluation based on experience with industrial, food processing, dairy and cheese manufacturing applications. Rob assisted in developing a scope and fee proposals from each of the four manufacturers to pilot test their systems on site. (Brown and Caldwell)
