Kuyu: Tube Well, Where to Dig

Kuyu brings community water planning onto a shared map. Village members and funding partners join a site using its code, mark households, existing water points and barriers, and review the same information.

Enter household size, dry- and wet-season trips and whether vulnerable people carry water. Confirm or dispute marks and report inappropriate content. A funder supplies the project budget, maximum wells and local installed-cost estimates for complete hand-pump wells and optional powered pumps.

The solver compares preliminary plans on a small candidate grid. It excludes marked barrier areas and a 30-meter buffer around marked latrine areas. Each returned plan fits the entered budget and well limit, includes the selected pumps, and shows all proposed locations and the total estimated cost. If the limits leave no plan, Kuyu explains why.

Compare estimated dry- and wet-season walking-burden reductions and the worst-served household. Straight routes that cross marked barriers receive no benefit. The app discloses when it uses a limited search and when a missing current source uses a 3 km comparison baseline. This is not a surveyed walking network: actual paths and land permissions remain unverified.

Water quality, suitable drilling depth and dry-season yield are unknown. Kuyu does not produce a contamination probability from water-point status reports. Obtain a field survey, site-specific quotes and water tests before drilling or spending money.

Both a villager and a funder must agree to the same current plan. The record includes the full well plan, estimated cost, pump choice and both timestamps. Earlier records remain visible; a completed agreement cannot be replaced by recalculating.

Submitted marks are cached on the device and queued for synchronization after a connection returns. The server calculates plans; this needs internet access. Shared site records, budgets and earlier solver inputs remain on Kuyu's Cloudflare backend. Keep the site code private and avoid unnecessary personal details in notes.

Kuyu does not process payments, escrow or commissions. It does not rank people or sell site data.
