Main Canal Concrete Lining — Phase IV

Phase IV continues the District’s long-term program of replacing earthen canal sections with slip-formed concrete lining. Seepage testing along this reach measured losses of more than 15 percent of flow between the upstream and downstream measurement points during the summer irrigation season. The lined section restores design capacity, allows higher flow velocities without bank erosion, […]

Lateral 9 Buried Pipeline Conversion

Open laterals in developed areas are costly to maintain and vulnerable to trash, encroachment and evaporation. This project replaces the Lateral 9 open channel with buried reinforced concrete pipe sized to carry the full design flow of the lateral. Turnouts are rebuilt with gated risers and propeller meters so that each account receives a measured […]
