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 (untreated) | Volume | Infrastructure |
|---|---|---|---|---|
| Spring (gravity-fed) | Very high | Often excellent (natural filtration) | Moderate-high | Collection box + pipe |
| Deep well (50+ feet) | Very high | Usually good | Moderate | Drilling/digging + pump |
| Shallow well (10-30 feet) | High | Variable (contamination risk) | Low-moderate | Hand-dug + pump |
| River/stream | High (seasonal) | Poor (surface contamination) | Very high | Intake + filtration required |
| Lake/pond | High | Poor-moderate | Very high | Intake + filtration required |
| Rainwater | Moderate (climate-dependent) | Good (if clean catchment) | Variable | Roof + gutters + cistern |
| Fog collection | Low-moderate (coastal/mountain) | Good | Low | Mesh nets + collection trough |
Daily water needs: Drinking: 1 gallon/person/day. Cooking: 0.5 gallon/person/day. Hygiene: 2-5 gallons/person/day. Livestock: 5-30 gallons/animal/day. Garden: 0.5-1 gallon per square foot per week. Total community: plan for 20-50 gallons/person/day minimum.
Chapter 2: Well Construction
| Type | Depth | Diameter | Method | Yield | Cost/Effort |
|---|---|---|---|---|---|
| Hand-dug (open) | 10-40 feet | 3-5 feet | Dig with shovel, line with stone/brick | 1-10 GPM | Very high labor |
| Driven point | 15-30 feet | 1.25-2 inches | Pound pipe with screen into ground | 1-5 GPM | Low-moderate |
| Drilled (hand auger) | 20-100 feet | 4-6 inches | Rotate auger, remove cuttings | 1-20 GPM | Moderate |
| Drilled (machine) | 50-500+ feet | 4-8 inches | Rotary or percussion drill | 5-50+ GPM | Very high (equipment) |
| Dug + bored (combination) | 20-60 feet | 3-4 feet + 6 inch bore | Dig to water table, bore deeper | 5-20 GPM | High labor |
Hand-dug well: Dig 3-4 feet diameter. Line walls with stone, brick, or concrete rings as you go (prevents collapse). Continue below water table until 3-5 feet of water stands. Install pump. Cap well to prevent contamination. Minimum 50 feet from any latrine or animal pen.
Chapter 3: Water Purification
| Method | Effectiveness | Volume | Energy | Equipment | Removes |
|---|---|---|---|---|---|
| Boiling (1 minute rolling) | 99.9% pathogens | Any | High (fuel) | Pot + fire | Bacteria, viruses, parasites |
| Slow sand filter | 90-99% pathogens | High (continuous) | None (gravity) | Sand bed (3+ feet deep) | Bacteria, turbidity, some viruses |
| Biosand filter (household) | 90-99% | 12-20 liters/hour | None (gravity) | Concrete box + sand + gravel | Bacteria, turbidity |
| Ceramic filter | 99%+ bacteria | 1-3 liters/hour | None (gravity) | Ceramic pot (colloidal silver) | Bacteria, parasites, turbidity |
| Solar disinfection (SODIS) | 99.9% (6 hours full sun) | 1-2 liters per bottle | None (solar) | Clear PET bottles | Bacteria, viruses |
| Chlorination | 99.9%+ | Any | None | Bleach (8 drops/gallon) or calcium hypochlorite | Bacteria, viruses |
| Activated charcoal | Chemical removal | Moderate | None (gravity) | Charcoal column | Chemicals, taste, odor (NOT bacteria) |
| Distillation | 99.99% everything | Low (1-2 liters/hour) | Very high (fuel) | Still (pot + condenser) | Everything (including salt, chemicals) |
Multi-barrier approach: Best practice = multiple treatment steps. Example: 1. Settle (let particles drop). 2. Filter (sand or ceramic). 3. Disinfect (boil, chlorine, or UV). Each step catches what the previous missed.
Chapter 4: Water Storage
| Container | Volume | Material | Lifespan | Cost | Notes |
|---|---|---|---|---|---|
| Cistern (underground) | 500-50,000 gallons | Concrete, stone, or ferrocement | 50-100+ years | High (one-time) | Best for large storage, stays cool |
| Above-ground tank | 100-10,000 gallons | Ferrocement, plastic, metal | 20-50 years | Moderate-high | Easier to build, needs shade |
| Rain barrel | 50-100 gallons | Plastic, wood, or metal drum | 10-30 years | Low | Good for garden irrigation |
| Ferrocement tank | 500-5,000 gallons | Wire mesh + cement mortar | 30-50+ years | Moderate | Can build any shape, very strong |
| Elevated tank (gravity-fed) | 100-2,000 gallons | Metal, plastic, or ferrocement | 20-50 years | Moderate-high | Provides pressure without pump |
| Pond (lined) | 10,000-1,000,000+ gallons | Clay-lined or synthetic liner | Indefinite | Moderate | Irrigation, livestock, fire suppression |
Ferrocement cistern: Build form (removable). Wrap with chicken wire + rebar mesh. Apply 3-4 layers cement mortar (1:3 cement:sand). Cure 28 days (keep moist). Waterproof interior with cement slurry or food-safe sealant. Extremely strong and long-lasting.
Chapter 5: Distribution Systems
| System | Pressure Source | Range | Complexity | Maintenance |
|---|---|---|---|---|
| Gravity-fed (spring/tank above) | Elevation difference | Unlimited (if source higher) | Low | Low (clear blockages) |
| Hand pump (well) | Human power | Point source only | Low-moderate | Moderate (seals, valves) |
| Windmill pump | Wind | Well to tank | Moderate | Moderate (mechanical) |
| Ram pump (hydraulic) | Water flow energy | Lifts water 10× fall height | Low-moderate | Very low (2 moving parts) |
| Solar pump | Solar panels + DC pump | Well to tank | Moderate-high | Low (no moving parts in panels) |
| Treadle pump | Human power (foot) | Shallow well to surface | Low | Low |
Gravity-fed system: Source must be higher than delivery point. Every 1 foot of elevation = 0.43 PSI pressure. Typical house needs 20-40 PSI = source 50-100 feet higher. Use PVC or polyethylene pipe. Size pipe for flow rate (1-inch pipe = 5-10 GPM at moderate pressure).
Ram pump: Uses energy of falling water to pump a portion of that water to a higher elevation. Needs: flowing water with 3+ feet of fall. Pumps 10-20% of water flow to 10× the fall height. No fuel, no electricity. Only 2 moving parts (valves). Runs 24/7 automatically.
Chapter 6: Water Quality Testing
| Test | Method | Acceptable Level | Frequency | Importance |
|---|---|---|---|---|
| Turbidity (clarity) | Visual (can you read through it?) | Clear (< 5 NTU) | Daily | Indicates contamination |
| Coliform bacteria | H2S test strip or lab | 0 per 100 mL (drinking water) | Monthly | Indicates fecal contamination |
| pH | Litmus paper or pH strips | 6.5-8.5 | Monthly | Affects treatment, pipe corrosion |
| Chlorine residual | DPD test strips | 0.2-0.5 mg/L (if chlorinating) | Daily (if treating) | Confirms disinfection |
| Hardness | Soap test (lather difficulty) | Preference (not health concern) | Annually | Affects soap use, scale buildup |
| Iron/manganese | Visual (orange/black staining) | < 0.3 mg/L iron | Annually | Taste, staining (not health) |
| Nitrate | Test strips | < 10 mg/L | Annually | Indicates agricultural/septic contamination |
Reference Card
- Spring: best water source. Gravity-fed, naturally filtered, reliable. Protect spring box from contamination.
- Multi-barrier: settle → filter → disinfect. Each step catches what the previous missed. Never rely on one method alone.
- Boiling: 1 minute rolling boil kills all pathogens. Most reliable purification method. Uses fuel.
- Slow sand filter: 3+ feet of sand, gravity-fed. Biological layer (schmutzdecke) does the work. 90-99% pathogen removal.
- Ram pump: free pumping using water flow energy. No fuel, no electricity. Lifts water 10× fall height. Only 2 moving parts.
- Gravity system: 1 foot elevation = 0.43 PSI. Need source 50-100 feet above delivery for household pressure.
- Storage: ferrocement cistern lasts 50+ years. Underground stays cool. Size for 3-7 days supply minimum.
- Test monthly: coliform bacteria test is most important. Zero coliform = safe. Any positive = treat and investigate source.
