Operating the Gravity-Fed System

What happens here

The presenter demonstrates the operation of the cistern's gravity-fed system. He opens a valve located near the base of the cistern using a custom-made tool from an old bike rack. This releases the stored water into the underground piping system, which then flows to the lower-elevation Mirafount tanks. He highlights the clear, cool water in the cistern and mentions using goldfish and creek snails to maintain water quality and prevent mosquito larvae.

Goal: Activate water flow from the cistern to the lower tanks via gravity.
