California is home to one of the most active water resource infrastructure sectors, and geosynthetics play an enormous role with the creation and rehabilitation of these water resources. The active site work for the substantial update to the Palos Verdes Reservoir began in late 2016, advanced primarily throughout 2018 and concluded in the second quarter of 2019 with the filling of the reservoir. The project was immense, and with that came expected excitement and challenges throughout the journey, read the entire series to gain in-depth details of the latest techniques and methods used during the installation work for the sustainable geosynthetics liner and floating cover system.
The Palos Verdes Reservoir in Los Angeles County boasts an impressive service life. The original construction was completed in 1939. Over the years, the site has played an important role in the Metropolitan Water District (MWD) of Southern California’s potable water network. The avocado-shaped facility has seen major changes to the reservoir included revitalizing the subgrade, reducing the operating volume from 1,000 to 614 acre-feet (326 million gallons [1.2 billion liters] to 200 million gallons [757 million liters]), and installing new geosynthetic lining and floating cover systems.
The Raven CLI Construction installation team was awarded this large-scale project to design, fabricate, and install geocomposite and geomembrane liner along with a custom floating cover system. For this project the team installed 60-mil (1.5-mm) liner and 45-mil (1.1-mm) floating cover panels. Raven geosynthetics sales and construction specialists are always available to recommend complete geosynthetics project solutions from design concept to completion. The team integrates a unique modular construction approach into project design and installation by producing large prefabricated geomembrane panels to be further fabricated on site. Quality factory panels are custom fabricated and mapped to exact specifications, eliminating up to 80% of field seams on site and significantly reducing labor, testing, weather exposure, and days on-site.
Raven Engineered Films is an experienced world-class manufacturer of advanced multi-layer geomembranes for the effective containment of liquids, solids, odors and hazardous gasses. Raven product lines include a wide-range of geomembranes including RPE, RPP, PVC, EPDM, CSPE, HDPE, LLDPE, fPP, along with all the supportive geosynthetic to complete a seamless installation.
