Santa Ana 2020 Urban Water Management Plan arcadis.com 9-10  Landscape Training Classes provide Santa Ana’s residents with an opportunity to learn about rainwater capture, gardening practices that build a healthy soil, proper plant selection that are consistent with our local environment. These classes educate City’s customers to conserve water in their landscapes through sound practices and water-wise choices.  Choice School Programs The City of Santa Ana collaborates with MWDOC to provide educational programs and activities for the City’s youngest water users. Through this collaboration, the City has supplied its K-12 students with water-focused learning experiences for nearly five (5) decades. Interactive, grade-specific lessons invite students to connect with, and learn from, their local ecosystems, guiding them to identify and solve local water-related environmental challenges affecting their communities. Choice School Programs are aligned with state standards, and participation includes a dynamic in-class or virtual presentation, and pre- and post-activities that encourage and support Science, Technology, Engineering, Arts and Mathematics (STEAM)-based learning and good water stewardship.  City of Santa Ana’s Annual Youth Water Poster Contest is an annual activity developed to encourage City’s K-12 students to investigate and explore their relationship to water, connect the importance of good water stewardship to their daily lives, and express their conclusions creatively through art. Each year, the City of Santa Ana receives hundreds of entries, and 12 winners from across the City are invited to attend a special awards ceremony with their parents and teachers. 9.1.5 Programs to Assess and Manage Distribution System Real Loss Senate Bill 1420 signed into law in September 2014 requires urban water suppliers that submit UWMPs to calculate annual system water losses using the water audit methodology developed by the AWWA. SB 1420 requires the water loss audit be submitted to DWR every five years as part of the urban water supplier’s UWMP. Water auditing is the basis for effective water loss control. DWR’s UWMP Guidebook include a water audit manual intended to help water utilities complete the AWWA Water Audit on an annual basis. A Water Loss Audit was completed for the City which identified areas for improvement and quantified total loss. Based on the data presented, the three priority areas identified were water imported, billed metered, and unauthorized consumption. Multiple criteria are a part of each validity score and a system wide approach will need to be implemented for the City’s improvement. The City completes a system water audit to calculate water losses on an annual basis. As part of the AMI project, the City will be adding the customer leak detection and system leak detection sensors system-wide. Expressing water loss audit results in terms of Real Losses per Service Connection per Day allows for standardized comparison across retailer agencies and is a metric consistent with the Water Board’s forthcoming economic model. The Real Losses per Service Connection per Day for calendar year 2019 was 19.59 gal/connection/day.
