Off-grid hydro installation with rocks in pipe

Very midgy installation, also with many small rocks being drawn into pipeline by the vacuum from closing the intake sluice. Some good pipe flushing action. Turbine is sited outside old shed to be on top of tailrace.
Ultimately frustrated due to record drought conditions. Only enough water in storage pond for a few hours of operation. Waiting for rain now. New Sunny island inverter and batteries and legacy Lister diesel. Some breeding Falcons and a collie dog.
