IRRP Upper District Leave Behind
IRRP INDIRECT REUSE REPLENISHMENT PROJECT CALIFORNIA IS CURRENTLY EXPERIENCING THE MOST SEVERE AND PROLONGED DROUGHT IN RECORDED HISTORY. WHO ARE WE? The Upper San Gabriel Valley Municipal Water District was incorporated in 1959 and covers approximately 144 square miles of the San Gabriel Valley. It services 18 cities and portions of unincorporated Los Angeles County with more than 1 million residents. Upper District partners with many public and private entities to provide a sustainable, high-quality water supply to the residents of the greater San Gabriel Valley. WHAT IS IRRP? WHY DO WE NEED IT? The Upper San Gabriel Valley Municipal Water District (Upper District) is working to expand its existing recycled water program by developing the Indirect Reuse Replenishment Project (IRRP) – a safe, reliable, water resource project to supplement the current water supply in the San Gabriel Valley. There is no better time for us to tap into a practice that has been in use for a half century to replenish record low groundwater supplies. The IRRP will replenish the severely depleted Main San Gabriel Groundwater Basin with up to 10,000 acre-feet annually of highly treated recycled water. The project will reduce the San Gabriel Valley’s reliance on imported water by 25 percent, providing a reliable, droughtresistant water resource that is essential given California’s dire drought conditions. California is currently experiencing the most severe and prolonged drought in recorded history. Without a long-term, reliable source of replenishment water, a sustained reduction of groundwater levels in the Main San Gabriel Groundwater Basin has the potential to impact the availability of water to the San Gabriel Valley. The California State Water Resources Control Board and Gov. Jerry Brown have called for increased investment in sustainable water supplies such as groundwater replenishment with highly treated recycled water. Contact: 602 E.

Recycled water has been commonly used for irrigation and industrial uses and is increasingly being used for groundwater replenishment. Highly treated recycled water will be pumped from the San Jose Creek Water Reclamation Plant to the Santa Fe Spreading grounds through a proposed 9-mile pipeline adjacent to the San Gabriel River. Industry experience and state-of-theart research were incorporated to ensure compliance with all local and State drinking water regulations. More than 50,000 acre-feet per year of this very same highly treated recycled water has been used for over 50 years to replenish the Central Basin, also in the San Gabriel River Watershed. IS IT SAFE? Groundwater recharge with highly treated purified recycled water has been proven a safe, pure, reliable water supply for over 50 years in Southern California. There are 7 projects currently operating to replenish groundwater basins with almost 200,000 acre-feet per year and over 20 additional projects under various stages of development in Southern California alone. Several of these projects practice ‘surface spreading’, a process that takes advantage of Soil Aquifer Treatment, a natural purification process that occurs through the percolation and travel of water in the ground that effectively treats the water further. Upper District was the agency sponsor for a national research program with the WateReuse Research Foundation to assess the benefits of purification alternatives prior to SAT. The project team included several industry experts who pioneered this new technology of water purification. Research testing results have continually exceeded expectations resulting in water quality results that are above the Safe Drinking Water Act requirements." WHY IS IT POSITIVELY RECEIVED BY THE PUBLIC? In this time of scarce water supply and increasing concern about the environment, public support is growing dramatically for water reuse projects. Public support for various recycled water projects jumped from 26 percent in 2004 to 73 percent in 2012. Scientists and public health professionals have played key roles in designing and monitoring the process throughout its development, and we can assure the public that this is a safe way to provide reliable water supplies. KEY PROJECT ELEMENT SOIL AQUIFER TREATMENT PROCESS This Soil Aquifer Treatment (SAT) process will allow more than two years of significant quality improvements through physical, chemical and biological processes through natural filtration. SAT is a widespread practice in southern California for more than 50 years. Soil Aquifer Treatment Process HOW CAN YOU HELP? Currently, the project is in the design phase, expected to be completed in fall 2016. The required permits and environmental documentation are expected to be completed in early 2016. Construction is planned to begin in spring 2017. The project is expected to be fully operational by late 2018. We are asking for your support to help secure water bond financing for this important project. The project will benefit all water users in the San Gabriel Valley by replenishing the severely depleted groundwater supplies in the Main San Gabriel Groundwater Basin and by providing a safe, long-term, reliable water supply.
