Sovereignty Module: Command the Waters
Complete Water Systems: From Source to Distribution
Clean water is the first requirement of civilization. This campaign covers finding water, purification, storage, distribution, and irrigation from primitive to advanced methods.
Chapter 1: Water Sources
| Source | Reliability | Quality | Access Method | Treatment Needed |
|---|---|---|---|---|
| Spring (uphill) | High | Usually excellent | Capture at emergence | Minimal (test first) |
| Deep well (50+ ft) | Very high | Usually good | Drill or dig | Usually minimal |
| Shallow well (10-30 ft) | Moderate-high | Variable | Dig, line, cap | Filter + disinfect |
| River/stream | High (seasonal) | Poor-moderate | Direct access | Full treatment required |
| Lake/pond | High | Poor-moderate | Direct access | Full treatment required |
| Rainwater | Seasonal | Good (if clean collection) | Roof + gutters + tank | Filter + disinfect |
| Fog collection | Low-moderate | Good | Mesh nets on ridges | Minimal |
| Seawater | Unlimited | Unusable (salt) | Distillation or reverse osmosis | Desalination required |
Chapter 2: Purification Methods
| Method | Effectiveness | Capacity | Energy | Cost | Best For |
|---|---|---|---|---|---|
| Boiling (1 min at rolling boil) | 99.9% pathogens | Any amount | High (fuel) | Free | Emergency, small quantities |
| Solar disinfection (SODIS) | 99.9% (clear water) | 2L per bottle | None (sun) | Free | Emergency, clear water only |
| Sand filter (biosand) | 95-99% bacteria, 90% virus | 20-50 L/hour | None (gravity) | Low | Community, ongoing |
| Ceramic filter | 99% bacteria, variable virus | 1-3 L/hour | None (gravity) | Moderate | Household, ongoing |
| Charcoal filter | Removes chemicals, taste, some bacteria | Variable | None (gravity) | Low | Pre-treatment, chemicals |
| Chlorination | 99.9% pathogens | Any amount | None | Very low | Large-scale, ongoing |
| Distillation | 100% (everything removed) | 1-5 L/hour | Very high (fuel) | Moderate | Saltwater, contaminated |
| UV (sunlight through glass) | 99.9% (clear water) | Small batches | None | Free | Clear water, small scale |
Biosand filter construction: 1) Container (concrete box, barrel, or large pot — 2-3 ft tall). 2) Bottom layer: large gravel (2 inches). 3) Middle layer: small gravel (2 inches). 4) Top layer: fine sand (18-24 inches). 5) Diffuser plate on top (prevents disturbing sand). 6) Outlet pipe from bottom. 7) Allow biofilm to develop (2-4 weeks of daily use). 8) Flow rate: 0.4 L/minute when mature. The biological layer (schmutzdecke) does most of the purification — don't disturb it.
Chapter 3: Storage and Distribution
| System | Capacity | Material | Elevation | Distribution |
|---|---|---|---|---|
| Clay pot | 5-50 gallons | Fired clay | Ground level | Manual carry |
| Cistern (underground) | 500-10,000 gallons | Concrete, stone, or lined | Below ground | Pump or bucket |
| Tank (elevated) | 100-5,000 gallons | Wood, metal, concrete | 10-50 ft above use point | Gravity (no pump needed) |
| Aqueduct | Continuous flow | Stone, concrete, pipe | Gradual slope (1-3%) | Gravity over distance |
| Ram pump | Continuous (1/7 of source) | Metal/PVC | Uses falling water energy | Pumps uphill automatically |
| Windmill pump | Variable (wind-dependent) | Metal/wood | Ground level to elevated tank | Wind-powered |
Gravity-fed system: Source (spring or stream) → Collection box (screened) → Pipe (downhill slope, 1-2% grade) → Storage tank (elevated) → Distribution pipes → Taps. No electricity needed. Pressure = 0.43 PSI per foot of elevation. 50 ft elevation = 21.5 PSI (adequate for household). Pipe sizing: 3/4 inch for single household, 1-2 inch for community.
Chapter 4: Irrigation
| Method | Efficiency | Labor | Best For | Water Use |
|---|---|---|---|---|
| Flood irrigation | 30-50% | Low (once built) | Rice, level fields | Very high |
| Furrow irrigation | 50-70% | Moderate | Row crops | High |
| Drip (gravity) | 85-95% | Low (once built) | Gardens, orchards | Very low |
| Swales (on contour) | 90%+ | Low (once built) | Orchards, food forests | Captures rain |
| Ollas (buried clay pots) | 90%+ | Very low | Gardens, dry climates | Very low |
| Wicking beds | 85-95% | Low (once built) | Raised bed gardens | Low |
Reference Card
- Boil if in doubt (1 minute rolling boil kills everything). 2. Gravity is free energy — elevate storage for pressure. 3. Biosand filter is the best long-term community solution. 4. Protect sources (fence, divert surface water away). 5. Test before trusting (clear water can still be contaminated). 6. Store in dark, covered containers (prevents algae). 7. Separate drinking water from irrigation water. 8. Rainwater collection: 1 inch of rain on 1,000 sq ft roof = 600 gallons.
