Hooper Water Improvement District
Hooper Water Treatment Plant | Iron and Manganese Removal

AQUA provided engineering design, procurement assistance, and construction support services for a groundwater treatment facility developed to address taste and odor concerns associated with a high-capacity municipal production well. Although the well was capable of producing approximately 2,700 gallons per minute (GPM), customers experienced water quality issues related to naturally occurring iron and manganese concentrations.
 
Working collaboratively with the District and its engineering team, AQUA conducted a detailed evaluation of the water quality concerns and identified iron and manganese as the primary contributors to the taste, odor, and aesthetic issues reported by customers. To develop an effective treatment solution, AQUA coordinated and oversaw an onsite pilot study utilizing a Pureflow treatment system to evaluate the treatability of the groundwater and determine the optimal process configuration.

Based on the pilot testing results, AQUA designed a treatment system utilizing chlorine oxidation followed by pressure filtration to effectively remove iron and manganese from the water supply. The oxidation process converts dissolved metals into filterable particles, while the pressure filtration vessels provide reliable removal of the precipitated solids and produce high-quality finished water.

To maximize water conservation and system efficiency, AQUA incorporated an innovative backwash recovery system into the facility design. The system includes a backwash settling tank that captures filter backwash water and allows iron and manganese solids to settle. Clarified water from the top of the tank is then returned to the treatment process, resulting in approximately 99 percent recovery of all water pumped from the well. Residual solids collected in the settling tank are discharged to the sanitary sewer system for disposal.

AQUA's responsibilities included treatment process design, preparation of construction drawings and technical specifications, equipment procurement assistance, bidding support, and limited construction management services. The completed project transformed a high-capacity groundwater source into a reliable and aesthetically acceptable drinking water supply while minimizing water waste and maximizing operational efficiency.
