City of Rialto, S1 Wastewater Treatment Plant Improvements Project

The Wastewater Treatment Plant (WWTP), constructed in 1955 and eventually expanded in later years, was in need of upgrades in order to continue providing reliable service to the community. There are five plants that make up the overall WWTP. Plant 1 is currently not in use and Plants 2, 3, 4 and 5 are in operation.
The Rialto S1 WWTP Improvements Projects is a Joint Venture Project between W.M. Lyles Co. (WML)/AECOM and consists on the following approach and strategy: To build the Plant 5 expansion, new disc filters and new CCT Disinfection “off-line” and after appropriate startup and testing bring the new facilities into service. Construction of Plant 5 facilities is the critical path and accordingly construction timing of other plant facilities will be adjusted so that all new facilities are ready for performance testing at the same time. Once new Plant 5 facilities are online, commissioned and successfully complete a 30-day performance test, we will next take the existing Plant 5 Aeration Basins off-line for effluent gate replacement and the anoxic zone baffle wall modifications. After first Aeration Basin work startup and testing is complete, the second existing Aeration Basin will be taken off-line and the needed improvements conducted. The project is currently on time and on budget.

City of El Paso de Robles, Wastewater Treatment Plant Upgrade Project

Upgrade to the existing wastewater treatment plant from 4.9 MGD to 12.74 MGD. This was accomplished by in part by replacing aging systems, including the trickling filter treatment process with a biological nutrient removal (BNR) system. Other improvements included three new secondary clarifiers, headworks ,DAFT facilities, operations, warehouse, cogeneration, and blower buildings, vehicle canopy, RAS pump station, WAS EQ tank, scum pump station, W-3 pump station, chemical feed facilities and effluent polishing earthen channel to discharge to the Salinas River. Efficiency upgrades included a cogeneration system to use digester bio-gas to generate heat and electricity. Listed construction improvements were coordinated with plant staff, and completed on this multiple phased construction project while the existing treatment process remained in operation.

Western Riverside County Regional Wastewater Authority, 14 MGD Plant Expansion Project

Construction of a 6.0 MGD expansion to an existing conventional WWTP that increases the treatment capacity up to 14.0 MGD. Construction activities include headwork’s expansion with new bar screens, washer compacter, and grit classifier, two primary clarifiers, equalization basin, bioreactor, bio filter, secondary clarifier, cloth disc tertiary filters, chlorine contact basin, recycle water pump station, masonry digester building, solar drying beds and odor control system, five electrical buildings and associated site electrical, instrumentation, piping, paving, and fencing. Upgrades to the existing plant include new centrifuges, fixed steel digester covers, odor control facilities, masonry thickener building and chemical building upgrades.

Victor Valley Wastewater Reclamation Authority, Subregional Water Reclamation Plants Project

The VVWRA Subregional Plants Project includes two individual 1 MGD scalping water reclamation plants (WRP), one located in the City of Hesperia and the other in the Town of Apple Valley. They treat a portion of the local wastewater, while all solids and the balance of the wastewater continues to the main treatment plant in Victorville. This scalping design provides needed reclaimed water to local agencies as well as reduce the impact of the wastewater flows on the existing pipeline system. The two facilities include odor control filters, storm water pump stations, reclaimed water pump stations, influent fine screens, two aeration basins, inline UV disinfection, Anaergia MBR including permeate and backwash pumping, RAS and WAS pumping station, percolation ponds, distribution piping, paving, and elaborate site fencing. In addition to the WRP sites there is also a Hesperia Lift Station site with a 40’ foot deep pump station, odor control filter, masonry electrical building and associated site piping, paving, and fencing. In all, there are 4 project site locations and 5 miles of pipeline traveling through the streets of Hesperia and the Town of Apple Valley.

LADWP, Silver Lake Reservoir Complete Storage Replacement Project

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

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

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.
