Sovereignty Module: Command the Waters
Complete Water Systems: From Source to Tap
Water is life. No settlement survives without reliable, clean water. This campaign covers finding, collecting, purifying, storing, and distributing water.
Chapter 1: Water Sources
| Source | Reliability | Quality | Volume | Development Cost | Best Climate |
|---|---|---|---|---|---|
| Spring (gravity) | Very high | Usually excellent | Variable (1-100+ GPM) | Low-moderate | Any (where geology permits) |
| Well (shallow, <25 ft) | High | Good (filter through soil) | Moderate (1-10 GPM) | Moderate | Any (high water table) |
| Well (deep, 25-200+ ft) | Very high | Usually excellent | Moderate (1-10 GPM) | High | Any |
| Stream/river | High (seasonal variation) | Variable (needs treatment) | High-unlimited | Low | Temperate, wet |
| Rainwater collection | Seasonal | Good (needs first-flush diversion) | Variable (depends on roof area) | Low-moderate | Wet climates (30+ in/year) |
| Lake/pond | High | Variable (needs treatment) | High-unlimited | Low | Any (where available) |
| Fog collection | Seasonal | Good | Low (1-10 gal/day) | Low | Coastal, foggy |
| Desalination | Unlimited (coastal) | Excellent (distilled) | Depends on system | High | Coastal, arid |
Chapter 2: Well Construction
| Method | Depth | Diameter | Equipment | Skill | Output | Best Soil |
|---|---|---|---|---|---|---|
| Hand-dug (open) | 10-50 ft | 3-5 ft | Shovel, bucket, forms | Low-moderate | High (large diameter) | Soft soil, no rock |
| Driven point | 10-30 ft | 1.25-2 inch | Drive point, pipe, driver | Low | Low-moderate | Sand, gravel (no rock) |
| Hand-augered | 10-50 ft | 4-8 inch | Hand auger, casing | Moderate | Moderate | Soft soil, clay |
| Cable tool (percussion) | 50-500+ ft | 4-8 inch | Drill rig, cable, bit | High | Moderate-high | Any (including rock) |
| Jetted | 10-50 ft | 2-4 inch | Water pump, pipe, jet nozzle | Moderate | Moderate | Sand, gravel |
Hand-dug well: Dig 3-5 ft diameter shaft. Line with stone, brick, or concrete rings as you go (prevents collapse). Continue until 3-5 feet into water table. Install well cover (prevent contamination). Pump or bucket for extraction. Advantages: large storage volume, simple tools, repairable. Risks: collapse (always shore), contamination (seal top), drowning.
Chapter 3: Water Purification
| Method | Removes | Effectiveness | Equipment | Speed | Scale |
|---|---|---|---|---|---|
| Boiling (1 min rolling) | Bacteria, viruses, parasites | 99.9%+ (pathogens) | Fire, container | Slow (heat + cool) | Small-medium |
| Slow sand filter | Bacteria, parasites, turbidity | 95-99% (bacteria), 99%+ (parasites) | Sand, gravel, container | Slow (continuous) | Medium-large |
| Rapid sand filter | Turbidity, large particles | Moderate (pre-treatment) | Sand, gravel, container | Fast | Large |
| Charcoal filter | Chemicals, taste, odor, some bacteria | Good (chemicals), moderate (bacteria) | Activated charcoal, container | Moderate | Small-medium |
| Solar disinfection (SODIS) | Bacteria, viruses | 99.9% (6 hours full sun) | Clear PET bottles | Slow (6+ hours) | Very small |
| Chlorination | Bacteria, viruses | 99.9%+ | Bleach (8 drops/gallon) | Fast (30 min wait) | Any |
| Distillation | Everything (produces pure water) | 100% | Heat source, condenser | Very slow | Small |
| Ceramic filter | Bacteria, parasites, turbidity | 99%+ (bacteria) | Ceramic pot filter | Slow-moderate | Small-medium |
| UV light | Bacteria, viruses | 99.9%+ | UV lamp or sunlight | Fast (seconds-minutes) | Small |
Slow sand filter (best community system): Container (barrel, concrete tank). Layers from bottom: 6" gravel (large), 6" gravel (small), 3" coarse sand, 24-36" fine sand, 2" water above sand (always). Flow rate: 0.1-0.3 GPM per square foot of surface. Biological layer (schmutzdecke) forms on top after 2-3 weeks — this is what purifies. Never let filter dry out. Scrape top 1" when flow slows.
Chapter 4: Water Storage
| Type | Capacity | Material | Lifespan | Cost | Best For |
|---|---|---|---|---|---|
| Clay pot/urn | 5-50 gallons | Fired clay | 10-50+ years | Low | Household, cooling |
| Wooden barrel | 30-55 gallons | Oak, cedar | 10-30 years | Moderate | Household, transport |
| Concrete cistern | 100-10,000+ gallons | Reinforced concrete | 50-100+ years | Moderate-high | Community, rainwater |
| Ferrocement tank | 100-5,000 gallons | Wire mesh + cement plaster | 30-50+ years | Low-moderate | Community, developing areas |
| Earthen pond (lined) | 1,000-1,000,000+ gallons | Clay-lined excavation | Indefinite | Low (labor-intensive) | Irrigation, livestock |
| Stone/masonry tank | 100-5,000 gallons | Stone, mortar | 100+ years | High | Permanent installations |
| Plastic tank | 50-10,000 gallons | Polyethylene | 15-25 years | Moderate | Modern installations |
Ferrocement tank: Most cost-effective large storage. Build form (removable). Wrap with chicken wire + rebar. Plaster with cement mortar (1:3 cement:sand) in 3 coats. Cure 7 days (keep wet). Waterproof interior with cement slurry. 1,000 gallons = 5 ft diameter × 7 ft tall.
Chapter 5: Water Distribution
| System | Pressure Source | Range | Complexity | Maintenance | Best For |
|---|---|---|---|---|---|
| Gravity feed (spring/tank uphill) | Elevation (1 PSI per 2.31 ft) | Unlimited (downhill) | Low | Very low | Permanent, reliable |
| Hand pump (shallow well) | Human power | At well location | Low | Low-moderate | Household, village |
| Windmill pump | Wind power | At well + elevated tank | Moderate | Moderate | Rural, windy areas |
| Ram pump (hydraulic) | Stream flow (no fuel) | Lifts water 10× fall height | Moderate | Low | Where stream available |
| Solar pump | Solar panels + DC pump | At well + tank | Moderate-high | Low | Sunny areas |
| Hand-carried | Human power | 200-500 yards practical | None | None | Emergency, temporary |
Ram pump: Uses energy of falling water to pump portion of water uphill. Requires: stream with 3+ foot fall, 1" minimum flow. Delivers: 1/7 to 1/10 of source flow to height 10× the fall. No fuel, no electricity, runs 24/7. Only moving parts: two valves (replaceable). Best water system for hilly terrain with streams.
Chapter 6: Water Quality Testing
| Test | Method | Safe Level | Indicator Of | Frequency |
|---|---|---|---|---|
| Turbidity (clarity) | Visual (read newspaper through jar) | Clear (can read through 12" water) | Sediment, particles | Daily |
| Odor | Smell | No odor | Contamination, algae | Daily |
| Taste | Taste (only if other tests pass) | No off-taste | Minerals, contamination | Weekly |
| pH | Litmus paper or pH strips | 6.5-8.5 | Acidity/alkalinity | Monthly |
| Coliform bacteria | Presence/absence test kit | Zero (absent) | Fecal contamination | Monthly |
| Hardness | Soap test (lathers easily = soft) | Preference (not health issue) | Mineral content | Annually |
| Nitrates | Test strips | <10 mg/L | Agricultural runoff, sewage | Annually |
Reference Card
- Boiling: simplest purification. 1 minute rolling boil kills all pathogens. Always safe. Use when unsure of any other method.
- Slow sand filter: best community water system. 24-36" fine sand over gravel. Biological layer purifies. Never let dry out.
- Ram pump: free water pumping using stream flow. No fuel, no electricity. Lifts water 10× the fall height. Runs 24/7.
- Gravity feed: most reliable distribution. Tank uphill, pipe downhill. 1 PSI per 2.31 feet of elevation. No moving parts.
- Storage: minimum 3 days supply per person (3 gallons/day). 1 gallon drinking + 2 gallons cooking/hygiene. More is better.
- Well safety: always cap/cover wells. Slope ground away from wellhead. Latrine minimum 100 feet away and downhill.
- Rainwater: 1 inch rain on 1,000 sq ft roof = 600 gallons. First-flush diverter (discard first 10 gallons). Screen for debris.
- Testing: clear, odorless, tasteless water can still be contaminated. Test monthly for coliform. When in doubt, boil.
