Water Reuse

EKI provides comprehensive water reuse services that help communities diversify water supplies, improve drought resilience, and advance One Water objectives. We support clients through every phase of reuse project development—from early planning and feasibility to permitting, design, and implementation—integrating technical, regulatory, and stakeholder considerations to deliver practical and defensible solutions.

Our team has deep expertise in evaluating and planning non-potable recycled water (NPR), indirect potable reuse (IPR), direct potable reuse (DPR), and decentralized reuse systems. We conduct feasibility studies, alternatives analyses, and demand assessments to identify reuse opportunities that align with local infrastructure, water quality requirements, regulatory frameworks, and long-term supply goals. EKI helps clients quantify water supply benefits, evaluate cost and risk, and prioritize projects that provide reliable, locally controlled supplies.

EKI also brings extensive experience navigating state and federal permitting and regulatory processes, particularly in California. We support compliance with recycled water regulations, drinking water standards, and environmental review requirements, and we work closely with regulatory agencies to advance projects through approval. Our services include preparation of engineering and planning documents, coordination with regulators, and development of monitoring and reporting frameworks that ensure long-term compliance and public health protection.

Water reuse is most effective when integrated with broader water management strategies. EKI applies a One Water lens to reuse planning, linking recycled water and potable reuse with stormwater capture, groundwater recharge, surface water management, and water use efficiency. Through stakeholder and community engagement, we help clients build understanding and support for reuse projects that deliver multiple benefits, including enhanced water supply reliability, reduced dependence on imported water, improved environmental outcomes, and long-term system resilience.
