water sovereignty requires clean infrastructure at every stage — from collection through distribution to discharge.
pipe materials
all water supply pipes within cyberia territory use PPR (polypropylene random copolymer):
food-grade PP-R80 or PP-R100 rated at PN16 minimum
no PVC, no galvanized steel, no lead solder in potable lines
reason: PPR contains no plasticizers, no heavy metals, no BPA — safe across the full temperature range for both cold and solar-heated supply
fittings: butt-fusion or electrofusion welded only — no glued slip joints in buried or concealed lines
collection standards
rainwater collection surfaces: food-grade coatings or stainless steel only — no asphalt-based or zinc-treated roofing in collection zones
first-flush diverters required on every roof catchment: minimum 1 L per 10 m² of collection area, auto-resetting
storage tanks: food-grade polyethylene or ferrocement with lime render interior — no fiberglass with styrene binders
covered storage: no open reservoirs in residential or food-production zones
greywater and blackwater
greywater (sinks, showers, laundry): on-site treatment before soil discharge — constructed wetland, living machine, or trickling filter to BOD < 30 mg/L
blackwater (toilets): closed composting system or biodigester — no direct discharge to soil or waterways
separation at source: greywater and blackwater lines plumbed independently from first fixture
discharge quality
effluent leaving any building or processing zone:
| parameter | limit |
|---|---|
| BOD | < 30 mg/L |
| TSS | < 50 mg/L |
| pH | 6.5 – 8.5 |
| nitrate | < 10 mg/L |
| phosphate | < 1 mg/L |
| coliforms | < 200 CFU / 100 mL |
monitoring: quarterly sampling at designated discharge points, results published to cyberia ledger
irrigation
drip irrigation preferred over sprinkler for food zones: 50% water reduction, zero foliar contamination
no agricultural-grade chemical fertilizers dissolved in irrigation lines
aquaponics effluent qualifies as irrigation source when fish density stays below 20 kg/m³
springs and surface water
15 m buffer zone around all springs — no construction, no chemical inputs, no tillage
surface water (streams, ponds): no discharge of soapy water, no vehicle washing within 30 m of banks
aquifer recharge zones (high infiltration andosol slopes): no soil sealing, no compaction by heavy machinery
