Recycled Water
Growing uncertainty in traditional sources of water supply and better understanding of treatment technology, both at the treatment plant and underground, have led to increasing public acceptance of recycled water use. Recycled water is municipal wastewater that has been purified through multiple levels of treatment. Recycled water is required to comply with stringent regulations to ensure that it is safe for approved uses such as irrigation and groundwater replenishment.
Drought conditions in California can lead to over-pumping of groundwater basins and reduced availability of surface water supplies. Recycled water provides a reliable, local, and high-quality source of water supply. As a result, California is a leader in the reuse of recycled water. The California State Water Resources Control Board’s (SWRCB’s) Recycled Water Policy has the stated goals of:
- Increasing recycled water use by at least one million acre-feet per year (AFY) by 2020 and by at least two million AFY by 2030
- Substituting as much recycled water for potable water as possible by 2030.
As part of drought relief measures, California has allocated $200 million in grants to recycled water projects. Todd Groundwater has been highly successful in assisting our clients in winning state grants for water projects. Todd Groundwater has considerable experience with recycled water projects including:
- Feasibility studies and implementation of recycled water recharge projects including spreading basins and vadose zone and aquifer injection
- Modeling of managed aquifer recharge impacts in terms of mounding, sustainability, and water quality
- Preparation of engineering reports for recycled water recharge projects in compliance with the California Division of Drinking Water’s Groundwater Replenishment with Recycled Water Regulations
- Preparation of Salt and Nutrient Management Plans assessing water quality impacts of recycled water projects in accordance with the SWRCB’s Recycled Water Policy
- Tracer studies to assess recycled water travel in the subsurface
