Rinconada Water Treatment Plant
Rinconada Water Treatment Plant
Los Gatos, California, United States
This project was for a water treatment plant that required pipe sizes ranging from 24-inch up to 84-inch to supply 12 filters with water for treatment.
Avon Lake Water Filtration Plant Improvements
Avon Lake Water Filtration Plant Improvements
Avon Lake, Ohio, United States
This steel pipe & headers were used to convey filter water improvements which was designed to test pilot one of the first filtration technologies in the USA, utilizing an electric grid to disinfect water for potable water distribution, being safer & a less costly alternative than chlorine.
Brookings Water Treatment Plant
Brookings Water Treatment Plant
Brookings, SD, United States
This project brought forth a new water treatment plant to replace an existing water treatment plant that was not only too small for its growing community but also had exceeded its useful life. The new water treatment plant can now treat 6 MGD of ground water compared to approximately 2.5 MGD by the old water treatment plant which opens the door for greater expansion into the rural and urban areas that were previously unreachable and now allows for streamlining water service and fire-protection coverage in the growth zones of the new water treatment plant.
Winner
Milestone Reservoir Tunnel & Shaft
Milestone Reservoir Tunnel & Shaft
Leesburg, Virginia, United States
This project involves converting an abandoned quarry into a raw water storage and pumping facility fed by the Potomac River. The work includes excavating a 6 foot diameter vertical shaft 239 feet deep, a 778 foot long horizontal tunnel, and installing new 36 inch and 42 inch steel water pipelines within the shaft and tunnel.
Surface Water Supply Project Central Pump Station
Surface Water Supply Project Central Pump Station
Katy, Texas, United States
This project involved the installation of large-diameter transmission piping ranging from 86” down to 38” OD, with multiple wall thicknesses to meet varying system demands. Below grade, the pipe was cement-mortar lined and protected with polyurethane coating. Above grade—at the pump stations and static mixers—the pipe was epoxy lined and epoxy coated to ensure long-term corrosion resistance in critical operational areas.
Harvest Water Pumping Station
Harvest Water Pumping Station
Sacramento, CA, United States
This project is a new pump station in the city of Sacramento, California. It ties into existing 72” and 66” pipe.
This project consists of 72” suction piping and 66” discharge piping connected to each other by 6 qty 30” pumps and 1 qty 20” pump with the ability to add an additional 30” as well as 3 surge tanks.
Materials used in this project meet the requirements of the Build America Buy America Act with the fabrication meeting the requirements of AWWA C200 for the steel pipe, AWWA C205 for the cement mortar lining, AWWA C207 for the flanges, AWWA C208 for the steel fabricated fitting
