A rainwater harvesting system: a volunteer-led effort in Depok

For five years the neighborhood has asked for a rainwater harvesting system. This year a group of 30 volunteers, including a retired civil engineer, decided to stop waiting. The council has given permission for the Maple community hall, but no funding. We have received donated a pump, and the remaining cost is $300. It will serve about 538 people, including elderly neighbors living alone. We'll hold a build day in April and everyone is invited. We're a small team, and every dollar will be spent in the open - I'll post receipts and progress photos. All purchases will be made by two volunteers and logged publicly. Surplus funds will go to maintenance. Where the $300 goes: • Materials: $160 • Permits and inspections: $35 • Safety equipment and signage: $35 • Tools hire and delivery: $70 Ask me anything below before you decide. I'd rather you were sure.
