Verified Outcomes
Key Architectural Deliverables & Takeaways
- Continuous independent access to mineral-rich deep artesian water with zero dependence on PRASA municipal rationing.
- Multi-barrier filtration combining 5-micron spun polypropylene, catalytic carbon block, and 254nm ultraviolet sterilization.
- Constant 62 PSI estate-wide hydro-pneumatic water pressure managed by a variable frequency drive (VFD) pump.
- Automated cistern level telemetry with low-level alarm and solar-matched pumping schedule.
1. Purpose & Scope
This Standard Operating Procedure (SOP) governs the extraction, storage, multi-barrier purification, and constant-pressure delivery of domestic water across all zones of Our Dream Villa, including the Upper Main Residence, Lower Guest Suite, Workshop, and Exterior Irrigation.

3. Routine Inspection & Maintenance Schedule
| Interval | Inspection Check | Action Required | Specification |
|---|---|---|---|
| Weekly | UV Chamber Ballast Status | Confirm green LED & audible beep test | 254nm @ >30,000 µW·sec/cm² |
| Monthly | 50-Micron Disc Pre-Filter | Turn manual purge valve to flush sediment | Clear flush for 15 seconds |
| Quarterly | Differential Pressure Gauges | Replace 5µm sediment and carbon filters | When ΔP exceeds 12 PSI |
| Semi-Annual | Storage Cistern Cleanliness | Visual inspection via sanitized access hatch | Clean sediment sweep if present |
| Annual | UV Quartz Sleeve & Lamp | Replace UV lamp; clean quartz tube with citric acid | 9,000 hour lamp life expiration |
4. Quarterly Filter Replacement Protocol
- Isolate the VFD booster pump by flipping circuit breaker #14 on Subpanel B.
- Close main ball valve upstream of the Stage 1 sediment filter housing.
- Depress the pressure relief red button atop filter sumps until flow ceases.
- Unscrew filter canisters using spanner wrench; discard exhausted cartridges.
- Sanitize interior canister bowls with 10% food-grade hydrogen peroxide solution.
- Lubricate EPDM O-rings with NSF-61 certified food-grade silicone grease.
- Insert new 5µm sediment filter into Sump 1 and catalytic carbon block into Sump 2.
- Tighten hand-tight plus 1/4 turn; slowly pressurize to purge trapped air via relief vent.
