Sovereignty Module: Tap the Spring
Complete Spring Development and Water Collection: From Seep to Supply
A developed spring provides the cleanest, most reliable water source available. This campaign covers spring identification, development, protection, gravity-fed systems, and water testing.
Chapter 1: Water Source Types
| Source | Reliability | Quality | Development Cost | Flow Rate |
|---|---|---|---|---|
| Gravity spring | Very high | Usually excellent | Low-moderate | 1-100+ GPM |
| Artesian spring | Very high | Usually excellent | Low | 1-50+ GPM |
| Seep (hillside) | Moderate-high | Good | Low | 0.1-5 GPM |
| Shallow well (hand-dug) | Moderate | Variable | Moderate | 1-10 GPM |
| Deep well (drilled) | High | Usually good | High | 5-50+ GPM |
Chapter 2: Spring Identification
Signs of groundwater: 1) Green vegetation in dry season. 2) Seeps and wet areas on hillsides. 3) Indicator plants: willows, cattails, rushes. 4) Animal trails converging on a point. 5) Fog rising from ground in early morning. 6) Cooler ground temperature. 7) Springs often emerge at contact between permeable and impermeable rock layers.
Chapter 3: Spring Development
Spring box construction: 1) Excavate around spring emergence point. 2) Dig to bedrock or impermeable layer. 3) Build collection box: concrete, stone, or food-grade plastic (3x3x3 feet minimum). 4) Overflow pipe near top. 5) Outlet pipe 6-12 inches below water surface. 6) Screened vent for air exchange. 7) Watertight lid prevents contamination. 8) Diversion ditch uphill routes surface water around spring box. 9) Fence area to keep animals away. 10) Backfill with gravel, then clay cap on top.
Chapter 4: Gravity-Fed Distribution
Gravity system design: 1) Spring must be higher than point of use. 2) Every 2.31 feet of elevation = 1 PSI of pressure. 3) Minimum 20 feet elevation difference for useful pressure. 4) Bury pipe below frost line. 5) Install air release valves at high points. 6) Storage tank provides buffer (1-3 days supply).
Chapter 5: Water Testing
| Contaminant | Safe Level | Treatment If Exceeded |
|---|---|---|
| Coliform bacteria | 0 per 100 mL | Chlorination, UV, boiling |
| E. coli | 0 per 100 mL | Chlorination, UV, boiling |
| Nitrate | Below 10 mg/L | Source protection |
| pH | 6.5-8.5 | Lime addition if acidic |
Reference Card
- Springs are the best water source (naturally filtered through rock and soil; no pumping cost). 2. Protect the recharge area (contamination uphill contaminates the spring). 3. A spring box protects the source (prevents surface contamination). 4. Gravity is free pressure (2.31 feet of elevation = 1 PSI). 5. Bury pipe below frost line. 6. Storage provides reliability. 7. Test water annually. 8. A diversion ditch is essential (routes surface runoff away from the spring).
