LADWP, Silver Lake Reservoir Complete Storage Replacement Project

Water Treatment

W. M. Lyles Co. has teamed with Webcor Builders and Obayashi Corporation to form Webcor, Obayashi, Lyles, (WOL) a Joint Venture CMAR for the Silverlake Complex Storage Replacement Project. WOL provides construction services and design support for LADWP to meet Federal Water Quality Regulations by con-structing two underground reservoirs and a 96’’ diameter pipeline which will re-place the operational function of the existing Silverlake and Ivanhoe reservoirs. Phase 1 of the project consists of the construction of a 55 million gallon concrete reservoir, connecting piping and a 3,000 foot long 12 foot diameter tunnel.

City of Fresno, Southeast Surface Water Treatment Facility

Water Treatment

The SESWTF is designed to treat 80 MDG of surface (river) water from the Kings River to provide potable water to City residents. This greenfield project includes the following processes; flow control struc-ture, pre-treatment basins (flocculation/sedimentation with plate settlers), ozone disinfection structure, and filters (GAC gravity filter). The facility also includes an 8MG treated water reservoir, chemical building, treated water and backwash pump station; washwater recovery and solids lagoons and associated pump stations, electrical substation, operations building, maintenance building, all site utilities (with pipelines up to 84”), landscaping and pavement throughout the site, perimeter block wall and offsite road utilities.

West Valley Water District, Rialto Groundwater Wellhead Treatment System Project

Water Treatment

The new 2.8 MGD Water Treatment Plant is designed to remove perchlorate from groundwater through a biological degradation process. This featured technology uses suspended bacteria to consume salt anions within a fluidized bed reactor (FBR) treatment system. After the FBR’s, the process follows the stages of a traditional plant including aeration tanks, Trident filters, a dissolved air flotation (DAF) unit and additional process equipment. Construction also included the excavation and haul off of contaminated material, two underground concrete tanks, concrete slabs-on-grade, masonry structures, a pre-engineered metal treatment building and all the associated piping, electrical, and controls.

Cal Water, Northwest Bakersfield WTP Increase Net Treatment Capacity Upgrade

Water Treatment

The Northwest Bakersfield Water Treatment Plant has been unable to achieve design capacity due to high turbidity water reaching the membrane filters which resulted in excessive backwashing and reduced plant output. W. M. Lyles Co. with Black & Veatch as a design sub consultant was selected to provide design-build services to increase plant capacity to 8 MGD (net) and 10.4 MGD (peak) by installing a pretreatment system ahead of the membrane filters. The project included the construction of a 0.42 MG gallon concrete Pretreatment Basin with four Flocculating Mixers, and two trains of Plate Settlers with Straight Line Residuals Sludge Collecting equipment. Mechanical piping sludge draw off from the basins to sewer occurs via a hydraulic head pressure siphon. A new onsite PACL chemical system was installed that included tank storage, chemical feed and flash mixing facilities. The existing earth retention basin was reconstructed and concrete lined to handle the treatment process backwash, system overflows and site storm water runoff. All work was constructed on a very congested site with limited available space for equipment laydown and construction operations.
