Site work for a water / sewer project in Palmdale, California. Completed plans call for site work for a water / sewer project.

The Palmdale Water District is accepting proposals from qualified general contractors to provide Construction Manager at Risk (CMAR) services consisting of pre-construction services, developing a Guaranteed Maximum Price (GMP), and performing all construction services at risk for the Construction Manager At-Risk (CMAR) Services for the Palmdale Ditch Conversion Project (the "Project"). The Palmdale Ditch (Ditch) was constructed in the 1880s and has been owned and operated by Palmdale Water District (PWD or District) since its completion. The Ditch, located in the city of Palmdale and unincorporated Los Angeles County, is a predominantly unlined, open-earthen channel that is used to convey raw water from Littlerock Reservoir to Lake Palmdale for treatment and beneficial use as potable water. PWD operates the approximately 8.5-mile-long Ditch intermittently in accordance with seasonal water availability and PWD water allocations. In 1995, approximately 1,900 feet of the Ditch, starting from the debris basin downstream of Littlerock Dam, was converted to a 54-inch diameter pipeline. In 2010, approximately 3,800 feet of the Ditch from Lake Palmdale to Sierra Highway was replaced with a 48-inch diameter reinforced concrete pipeline. In total, approximately 30 percent of the Ditch is either lined with concrete or utilizes culverts and tunnels to cross through steep terrain and beneath roadways, while almost 70 percent of its total length remains an unlined, open earthen ditch. There is also one remaining aerial flume supported by a steel trestle located midway between Sierra Highway and Pearblossom Highway and one piped crossing of the California Aqueduct. In 2021, PWD completed a feasibility study evaluating the potential water savings that could be achieved by replacing the remaining open channel segments with a buried pipeline and increasing the design flow from 20 cubic feet per second (cfs) to 60 cfs. The study concluded that water savings of approximately 1,450 acre-feet per year could be achieved. The purpose of the Palmdale Ditch Conversion Project (Project) is to convert the predominantly open-earthen Ditch to a buried 48-inch reinforced concrete or high-density polyethylene pipeline and increase the hydraulic capacity of the Ditch from 20 cfs to approximately 60 cfs. PWD has retained Hazen and Sawyer to develop the design for the Project. The design is currently being updated to a 90% design level.
