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 communities of any size.
Chapter 1: Water Sources
| Source | Reliability | Quality | Volume | Access Difficulty | Treatment Needed |
|---|---|---|---|---|---|
| Spring (gravity) | High (year-round) | Often excellent | Low-moderate | Low (if accessible) | Minimal (test first) |
| Well (shallow, <25 ft) | Moderate (seasonal) | Variable | Low-moderate | Moderate (digging) | Usually filtration |
| Well (deep, 25-200 ft) | High | Usually good | Moderate-high | High (drilling) | Minimal usually |
| River/stream | High (perennial) | Poor-moderate | High | Low | Full treatment required |
| Lake/pond | High | Poor-moderate | Very high | Low | Full treatment required |
| Rainwater | Variable (climate) | Good (after first flush) | Variable | Low (collection system) | Filtration + disinfection |
| Snowmelt | Seasonal | Good | Variable | Low | Filtration |
| Fog collection | Climate-dependent | Good | Low | Moderate (mesh system) | Minimal |
| Seawater (desalination) | Unlimited | Requires desalination | Unlimited | Very high (energy) | Distillation or reverse osmosis |
Chapter 2: Well Construction
| Type | Depth | Diameter | Flow Rate | Construction | Lifespan | Cost |
|---|---|---|---|---|---|---|
| Hand-dug (open) | 10-50 ft | 3-6 ft | 1-10 gal/min | Manual labor, shoring | 20-50+ years | Low |
| Driven point | 10-30 ft | 1.25-2 inches | 1-5 gal/min | Drive pipe with cap | 10-25 years | Very low |
| Bored (hand auger) | 10-50 ft | 4-8 inches | 1-10 gal/min | Hand auger, casing | 20-50 years | Low |
| Drilled (percussion) | 50-500+ ft | 4-8 inches | 5-50+ gal/min | Cable tool drilling | 30-50+ years | Moderate-high |
| Drilled (rotary) | 50-1,000+ ft | 4-12 inches | 5-100+ gal/min | Rotary drill rig | 30-50+ years | High |
Hand-dug well: 1) Select site (downhill from buildings, uphill from contamination). 2) Dig shaft 3-4 ft diameter. 3) Shore walls as you go (stone, brick, or concrete rings). 4) Continue until water-bearing layer reached (sand/gravel with water). 5) Dig 3-5 ft into water layer. 6) Install gravel filter at bottom (1 ft). 7) Line walls above water table (prevent surface contamination). 8) Build apron around top (concrete pad, sloped away). 9) Install cover (prevent contamination, child safety). 10) Install pump or windlass. Safety: never dig alone. Test air quality (candle test). Shore immediately. Cave-ins kill.
Chapter 3: Water Purification
| Method | Effectiveness | Volume | Speed | Cost | Complexity | Best For |
|---|---|---|---|---|---|---|
| Boiling (1 min at sea level) | 99.99% (all pathogens) | Any | Slow (fuel intensive) | Low (fuel cost) | Very low | Emergency, small volume |
| Solar disinfection (SODIS) | 99.9% (bacteria, virus) | 1-2 liters per bottle | 6-48 hours (sun) | Very low | Very low | Emergency, clear water |
| Slow sand filter | 99-99.9% (bacteria, protozoa) | 1-5 gal/hour/sq ft | Slow (gravity) | Low-moderate | Moderate | Community, ongoing |
| Rapid sand filter | 90-99% (turbidity, some pathogens) | High volume | Fast | Moderate | Moderate-high | Pre-treatment |
| Charcoal filter | Good (chemicals, taste, some bacteria) | Moderate | Moderate | Low | Low-moderate | Taste, chemicals |
| Chlorination | 99.99% (bacteria, virus) | Any | 30 min contact time | Very low | Low | Large volume, ongoing |
| UV light (if available) | 99.99% (all pathogens) | Flow-through | Instant | Moderate (equipment) | Moderate | Clear water, power available |
| Ceramic filter | 99.9% (bacteria, protozoa) | 1-3 liters/hour | Slow | Low-moderate | Low | Household, ongoing |
| Distillation | 100% (everything removed) | Low | Very slow | High (fuel) | Moderate | Desalination, contaminated |
Slow sand filter (community scale): 1) Container: concrete/masonry tank (4x4x4 ft minimum for family). 2) Bottom layer: 6 inches coarse gravel (supports sand). 3) Middle layer: 3 ft fine sand (0.15-0.35 mm grain size). 4) Top: 3-4 ft water above sand (head pressure). 5) Underdrain: perforated pipe in gravel layer (collects filtered water). 6) Flow rate: 0.1-0.3 gal/hour per square foot of surface. 7) Biological layer (schmutzdecke) forms on top of sand in 2-4 weeks — this is the primary purification mechanism. 8) Maintenance: scrape top 1 inch of sand when flow slows (every 1-6 months). Replace sand when depth drops below 2 ft. Simple, effective, no chemicals, no power. Used worldwide for 200+ years.
Chapter 4: Water Storage
| Type | Capacity | Materials | Lifespan | Cost | Best For |
|---|---|---|---|---|---|
| Barrel (wood) | 30-55 gallons | Oak, cedar | 20-50 years | Moderate | Household, rainwater |
| Cistern (masonry) | 500-10,000+ gallons | Concrete, stone, plaster | 50-100+ years | Moderate-high | Community, rainwater |
| Tank (metal) | 100-10,000 gallons | Galvanized steel | 20-40 years | Moderate-high | Any |
| Tank (plastic) | 50-10,000 gallons | Polyethylene | 15-25 years | Moderate | Any (if available) |

Chapter 5: Water Distribution
| System | Pressure Source | Range | Capacity | Complexity | Maintenance |
|---|---|---|---|---|---|
| Gravity (elevated tank) | Elevation (1 ft = 0.43 psi) | Unlimited (downhill) | High | Low-moderate | Low |
| Hand pump | Human power | Well depth dependent | Low (5-10 gal/min) | Moderate | Moderate |
| Windmill pump | Wind | Well depth dependent | Moderate (continuous) | High (initial) | Moderate |
| Ram pump (hydraulic) | Water flow (no external power) | 10x fall height | Low (1-5 gal/min) | Moderate | Low |
| Animal-powered (noria) | Animal walking in circle | Well/river | Moderate | Moderate | Moderate |
| Solar pump | Solar panels + electric pump | Well depth dependent | Moderate | High (initial) | Low |
Hydraulic ram pump: uses energy of falling water to pump a portion of that water to a higher elevation. No external power needed. Requirements: 1) Flowing water source with at least 3 ft of fall. 2) Drive pipe: 1-2 inch diameter, 5-10x the fall length. 3) Waste valve: opens/closes with water hammer. 4) Delivery valve: check valve to pressure tank. 5) Air chamber: absorbs shock, smooths delivery. 6) Delivery pipe: to elevated storage. Efficiency: pumps 10-20% of source water to 5-10x the fall height. Runs 24/7 with zero energy input. Maintenance: replace valves annually.
Chapter 6: Sanitation and Wastewater
| System | Capacity | Complexity | Maintenance | Effluent Quality | Best For |
|---|---|---|---|---|---|
| Pit latrine | 1 family (5 years) | Very low | None (dig new when full) | Poor (contained) | Emergency, temporary |
| Composting toilet | 1 family (ongoing) | Low | Regular (add carbon, empty) | Good (after 1 year) | Permanent, waterless |
| Septic system | 1-5 families | Moderate | Pump every 3-5 years | Moderate | Permanent, with water |
| Constructed wetland | 1-50 families | Moderate-high | Low (plant management) | Good | Community, permanent |
| Reed bed filter | 1-20 families | Moderate | Low | Good | Community, permanent |
| Greywater garden | 1 family | Low | Low | Moderate (irrigates) | Household, water reuse |
Composting toilet: 1) Build seat over collection chamber (5-gallon bucket or larger vault). 2) After each use: cover with carbon material (sawdust, wood shavings, dry leaves). 3) When full: seal container, date it, start new one. 4) Age minimum 1 year (pathogens die). 5) After aging: safe to use on fruit trees and non-food gardens. 6) No water needed. No smell if carbon cover used properly. 7) Produces valuable compost. 8) Works anywhere, any climate. The simplest, most sustainable sanitation system.
Reference Card
- Test before drinking: even clear water can contain pathogens. Boil or filter ALL surface water. Springs: test annually. Wells: test after construction and annually.
- Separate water uses: drinking water (highest quality) vs. washing water (moderate) vs. irrigation (lowest). Don't waste purified water on gardens.
- Gravity is free: elevate your storage tank. Even 10 ft of elevation provides useful pressure (4.3 psi). No pump needed for distribution. Build tank on hill or tower.
- Slow sand filter: the single best community water treatment. No chemicals, no power, no moving parts. Effective against bacteria and protozoa. Build one.
- Rainwater: free, relatively clean, and available everywhere it rains. 1 inch of rain on 1,000 sq ft roof = 600 gallons. Collect it. First flush diverter removes debris.
- Protect sources: keep latrines, animals, and chemicals DOWNHILL and 100+ ft from water sources. Contamination prevention is easier than treatment.
- Redundancy: multiple water sources. Well + rainwater + stream access. If one fails (drought, contamination, mechanical failure), others provide backup.
- Store water: minimum 3 days supply always on hand. Cistern or tanks. Rotate stock. Treat stored water (1/8 tsp bleach per gallon, or sealed containers).
