Agenda - City of Santa Monica

Implementation levels for each water conservation program modeled were based on
analyses of saturation rate of existing water saving plumbing fixtures and landscapes,
customer surveys, staff knowledge of the City’s customers and their willingness to
implement these programs, and products that will have long-term water savings that are
not dependent on significant changes in the customer’s behavior. The goal was to
develop a diverse selection of programs that aggressively pursued demand reduction
through retrofitting existing indoor plumbing that is already water-saving with plumbing
fixtures that save about twenty percent more water in addition to retrofitting landscapes
with plants and irrigation that can save up to eighty percent more compared to existing
landscapes.
The resulting suite of conservation programs (Table 1) is projected to save
approximately 775 AFY of water in the year 2020. An additional 420 AFY of savings is
expected in 2020 as a result of State plumbing and building code standards that require
higher water saving fixtures. In addition, a reduction in system-wide leaks and nonrevenue
water through capital investment in the system is projected to save another 250
AFY of water for a total demand reduction of approximately 1,443 AFY in 2020.
