Prior to this expansion project, the Pyramid Peak Water Treatment Plant (WTP) was rated to treat 48 million gallons of water per day (mgd) while operating on a reliable capacity of 39 mgd. The expansion increased the facility to a reliable capacity of 54 mgd. The expansion was deemed necessary to serve anticipated growth in the northern areas of the city of Glendale and city of Peoria in Arizona.
This plant is the primary means of treating wastewater in the service area, and several years prior to completion of construction, plant staff were challenged to operate the existing facilities for extended periods at or beyond the original design capacity of the plant.
W. M. Lyles Co. teamed with Anaergia, a global leader in both the agricultural and the waste sectors to deliver this one-of-a-kind, progressive design-build project. The Anaergia-Rialto Bioenergy Facility (RBF) addresses two pressing waste management issues in Southern California: food waste diversion from landfills and biosolids management.
The Tres Rios WRF Capacity and Effluent Quality Upgrade Project is the largest construction project completed in Pima County’s history. It satisfies the Clean Water Act’s stringent environmental regulatory requirements, meets RWRD’s long-term service needs, and augments precious water supplies for this growing desert community.
The City of Venice, Florida, needed to retrofit its existing reverse osmosis (RO) 4.5 mgd water treatment plant with new RO membrane skids that could meet the existing total demand situations and flow conditions. The plant also needed the flexibility in its operations to decrease the withdrawal of water from wells by using second-stage treatment and also increasing capacity without increasing well withdrawals through increased recovery.
The University of New Hampshire owns and is responsible for operations of a water treatment plant that serves the entire campus as well as the Town of Durham, NH. The original WTP was constructed in the early 1930s, and even though it continued to meet drinking water requirements, UNH decided to build a new facility due to the age of the equipment and structures. In addition to providing clean water for approximately 29,500 people, the design of the new WTP needed to address several unique needs for UNH.
To serve a growing population in an area often stricken by drought, San Diego County Water Authority began investigating the potential for a desalination project along the county’s coastline, eventually identifying the Carlsbad site due to the existing seawater intake and discharge infrastructure, as well as proximity to the regional distribution system. SDCWA then engaged developer Poseidon Water to design and construct a plant and conveyance pipeline as part of a 30-year Water Purchase Agreement for up to 56,000 acre-feet per year—or approx. 18.25 billion gallons.
The CSX Camden Street Storm Drain Replacement was a technically complex, design-build project located in a heavily traveled section of downtown Baltimore, Maryland, which consisted of replacing a 48-inch-diameter brick storm drain, originally built in 1891, that crosses directly under the CSX railroad tracks in the Howard Street Tunnel.
Upper Trinity Regional Water District’s (UTRWD) Riverbend Water Reclamation Plant (WRP) needed to increase its capacity from 2 mgd annual average daily flow to 4 mgd with a peak flow rate of 16 mgd. With project drivers determining that construction management at-risk would be the best delivery method, UTRWD chose Archer Western as their CMAR.
Water in the Four Corners region is in short supply for many communities and available water is often of poor quality. In order to mitigate water contamination and scarcity, the Navajo-Gallup Water Supply Project was conceived, and a significant portion of the project, the Cutter Lateral, is near completion in Summer 2020. Multiple state and federal agencies are involved with this massive project.
The City of Wichita’s ability to obtain adequate drinking water was threatened because their main source of water had become depleted and vulnerable to saltwater intrusion. To improve both the quantity and quality of available drinking water for the region, the City of Wichita’s Aquifer Storage and Recovery (ASR) project draws water from the Little Arkansas River during high flows, treats the water to drinking water standards, and then injects the treated water into the aquifer for recovery and use during drought conditions.
To solve water loss issues and reduce operation and maintenance costs, Denver Water solicited the services of a construction manager at-risk (CMAR) to remove and replace the existing Ashland Storage Basin Facility, located in the historic Highlands neighborhood, which was originally constructed in the 1890s as an open-air reservoir with earthen bottoms.
