Sovereignty Module: Command the Waters
Complete Water Systems: From Source to Tap
Water is life. This campaign covers finding, collecting, purifying, storing, and distributing water for drinking, agriculture, and industry.
Chapter 1: Water Sources
| Source | Reliability | Quality | Access Method | Flow Rate | Best For |
|---|---|---|---|---|---|
| Spring (gravity) | High (year-round) | Usually excellent | Capture at emergence | 1-100+ GPM | Drinking, all uses |
| Stream/river | High (seasonal variation) | Variable (needs treatment) | Direct access | High | Agriculture, industry |
| Well (shallow, <25 ft) | Moderate | Good (filtered by soil) | Hand-dug, lined | 1-10 GPM | Household |
| Well (deep, 25-200 ft) | High | Excellent (deep filtration) | Drilled/driven | 1-20 GPM | Household, livestock |
| Rainwater | Seasonal | Good (needs first-flush diversion) | Roof collection | Variable | Household, garden |
| Lake/pond | High | Variable (surface contamination) | Pump or gravity | High | Agriculture, industry |
| Snow/ice melt | Seasonal | Good | Collect and melt | Variable | Emergency, seasonal |
| Fog collection | Climate-dependent | Good | Mesh nets | 1-10 gal/day | Arid coastal areas |
Chapter 2: Purification Methods
| Method | Removes | Effectiveness | Speed | Equipment | Energy |
|---|---|---|---|---|---|
| Boiling (1 min at sea level) | Bacteria, viruses, parasites | 99.9% pathogens | Slow (fuel needed) | Pot + fire | High |
| Sand/gravel filter | Sediment, some bacteria | 90-99% (slow sand) | Moderate (gravity) | Layered container | None |
| Charcoal filter | Chemicals, taste, some bacteria | Good (chemical), moderate (bio) | Moderate | Charcoal + container | None |
| Solar disinfection (SODIS) | Bacteria, viruses | 99.9% (6 hours full sun) | Slow (6-48 hours) | Clear bottles | Solar |
| Chlorination | Bacteria, viruses | 99.9% | Fast (30 min) | Bleach (8 drops/gal) | None |
| Distillation | Everything (including salt, chemicals) | 100% | Very slow | Still | High |
| Ceramic filter | Bacteria, parasites, sediment | 99%+ bacteria | Slow (drip) | Ceramic pot | None |
| UV light | Bacteria, viruses | 99.9% | Fast (seconds) | UV lamp + power | Moderate |
Complete gravity filter (build from scratch): 1) Two containers (upper feeds lower). 2) Upper container: hole in bottom with screen. 3) Filter layers (bottom to top): gravel (2 in), coarse sand (4 in), fine sand (8 in), charcoal (4 in), gravel (2 in). 4) Water poured in top, drips through layers, collects in lower container. 5) Flow rate: 1-2 gallons per hour. 6) Maintenance: scrape top layer of sand weekly, replace charcoal monthly.
Chapter 3: Storage and Distribution
| System | Capacity | Materials | Elevation | Best For |
|---|---|---|---|---|
| Cistern (underground) | 500-10,000 gal | Stone, concrete, or lined pit | Below ground | Rainwater storage |
| Tank (elevated) | 100-5,000 gal | Wood, metal, or concrete | 10-50 ft above use point | Gravity distribution |
| Reservoir (pond) | 10,000-1M gal | Earthen dam + clay lining | Above use point | Agriculture, community |
| Spring box | 50-500 gal | Concrete or stone enclosure | At spring | Protecting spring source |
| Barrel/drum | 30-55 gal | Wood or metal | Any | Household storage |
Gravity distribution: Water stored at elevation flows downhill through pipes to users. Every 2.31 feet of elevation = 1 PSI of pressure. A tank 23 feet above the tap gives 10 PSI (adequate for household use). Pipe materials: bamboo (short-term), clay (moderate), wood (bored logs), copper, iron, or PVC.
Chapter 4: Irrigation
| Method | Efficiency | Complexity | Water Use | Best For |
|---|---|---|---|---|
| Flood/furrow | 40-60% | Low | High | Row crops, flat land |
| Raised bed (hand water) | 70-80% | Low | Moderate | Gardens, small scale |
| Drip (gravity) | 90-95% | Moderate | Very low | Gardens, orchards, dry climates |
| Sprinkler | 60-75% | High | Moderate-high | Large areas, lawns |
| Swale/contour | 80-90% | Moderate | Passive (rain) | Orchards, permaculture |
| Qanat/spring-fed channel | 85-95% | High (initial) | Passive (gravity) | Arid regions, permanent |
Gravity drip system: 1) Elevated barrel (4-6 ft above garden). 2) Main line (3/4 inch pipe/hose from barrel). 3) Distribution lines (1/4 inch tubing along rows). 4) Emitters (small holes or drip fittings every 12-18 inches). 5) Filter at barrel outlet (prevents clogging). 6) Flow rate: 1-2 gallons per hour per emitter. 7) Timer optional (or manual valve). No pump needed — gravity does the work.
Chapter 5: Sanitation and Wastewater
| System | Capacity | Complexity | Maintenance | Effluent Quality |
|---|---|---|---|---|
| Pit latrine | 1 family (5-10 years) | Very low | None until full | Contained (no effluent) |
| Composting toilet | 1 family (continuous) | Low | Monthly (add carbon) | Compost (after 1 year) |
| Septic system | 1-5 families | Moderate | Pump every 3-5 years | Moderate (leach field) |
| Constructed wetland | Community | Moderate-high | Low (plant management) | Good (natural treatment) |
| Greywater garden | 1 family | Low | Minimal | Reused (irrigation) |
Rule: Keep drinking water source at least 100 feet from and uphill of any latrine or waste disposal. Contamination of water supply is the #1 killer in post-collapse scenarios. Separate greywater (washing) from blackwater (toilet). Greywater can irrigate non-food plants directly.
Reference Card
- Gravity is free (elevate water source above use point — no pumps needed). 2. Filter before drinking (sand + charcoal removes most contaminants). 3. Boil if uncertain (1 minute at rolling boil kills all pathogens). 4. Separate waste from water (100 ft minimum, uphill from source). 5. Store water covered (prevents contamination, mosquitoes, evaporation). 6. Multiple sources (spring + well + rainwater = redundancy). 7. Drip irrigation saves water (90%+ efficiency vs. 40-60% for flood). 8. Test before trusting (clear water can still contain invisible pathogens).
