Complete Water Systems: From Source to Tap

Clean water is life. This campaign covers finding, collecting, purifying, storing, and distributing water for drinking, irrigation, and sanitation.

Hand-dug well procedure: 1) Select site (uphill from contamination, 100+ ft from latrine). 2) Dig 3-4 ft diameter hole. 3) Line walls as you go (stone, brick, or pre-cast rings). 4) Continue until water table reached + 3-5 ft into water. 5) Install gravel filter at bottom. 6) Cap top (prevent contamination). 7) Install hand pump or windlass. 8) Test water quality.

Biosand filter construction: 1) Container (concrete box, barrel, or bucket — 2-5 gallon minimum). 2) Layers from bottom: gravel (3 inches), coarse sand (3 inches), fine sand (18-24 inches), standing water (2 inches above sand). 3) Diffuser plate (prevents disturbing sand). 4) Outlet pipe at bottom. 5) Allow 2-3 weeks for biological layer to develop. 6) Never let sand dry out. Flow rate: 0.5-1 gal/hour per square foot of sand surface.

Ram pump: uses energy of falling water to pump small portion uphill. Requires: flowing water source with 3+ ft fall. Delivers: 1/7 of input water to 7x the fall height (approximately). No electricity, no fuel. Runs 24/7 automatically. Build from pipe fittings, check valves, and pressure chamber.

Reference Card

  1. Boiling: simplest purification. 1 minute at rolling boil kills everything. If fuel is available, this is the answer. No equipment needed beyond a pot.
  2. Biosand filter: build once, use for years. Fine sand + gravel + container. Biological layer develops in 2-3 weeks. Removes 99% bacteria. No consumables.
  3. Gravity: water flows downhill. If your source is above your use point, pipe it. No pump, no fuel, no maintenance. Ideal system.
  4. Ram pump: if you have flowing water with 3+ ft fall, a ram pump lifts water uphill for free. No electricity. Runs forever. Build from pipe fittings.
  5. Rainwater: 1 inch of rain on 1,000 sq ft roof = 600 gallons. Collect everything. Size tank for dry season. First flush diverter removes roof debris.
  6. Well location: 100+ ft from latrine, downhill from contamination. Uphill from septic. Test water annually. Cap well to prevent surface contamination.
  7. Storage: size for 3 days minimum household use (50 gal/person/day for all uses, 1 gal/person/day survival minimum). Covered, dark, clean.
  8. Drip irrigation: most efficient method. Gravity-fed from elevated tank. Emitters at each plant. 90-95% efficiency vs 40-60% for flood. Saves water, saves labor.
