To support regional water reuse and improve system efficiency, AKM conducted a feasibility study for an interconnection between El Toro Water District (ETWD) and Moulton Niguel Water District (MNWD). ETWD faces storage constraints at its recycled water plant, requiring potable water supplementation during peak demand and excess discharge during low demand. AKM’s study evaluated potential pipeline alignments, hydraulic impacts, and operational strategies to address these challenges.

Using MNWD’s hydraulic model, AKM simulated various interconnection scenarios by adjusting pump station operations, pressure relief valves, and altitude valve settings. Two primary alignments were analyzed, with the preferred option connecting at Sheep Hills Reservoir. This configuration effectively balanced system flows, minimized potable water use, and improved storage management.

The study included detailed recommendations for pipeline alignments, facility modifications, and a long-term operational plan. AKM’s analysis confirmed that the interconnection would enhance regional water reuse, reduce reliance on potable water, and create a more resilient and sustainable infrastructure for both districts.
