Well & Rainwater Conversion

Supply the pool and landscaping from the property's own water — the well storage tank and the rain-catchment tanks — with treatment sized by lab tests, two new pipe runs, tank telemetry into the /81 console, and a sourcing policy that decides which tank feeds what.

Gate ① — treatment routes for the well's mineral content pick with the lab numbers, not by feel

For a salt pool the usual well-water problems are iron & manganese (the salt cell oxidizes dissolved metal straight onto surfaces as stain), then calcium hardness (scale, especially with a heater), then TDS. Which problem this well has is unknowable until the panel comes back — so the route is pre-registered against thresholds: Fe+Mn < 0.3 ppm → A · 0.3–2 ppm → B or C · > 2 ppm → D · extreme CH/TDS → E. Route F pairs with any of them.

RouteWhat it isRight whenCapexOngoing / yrCapex range ($0–5.5k scale)
A Sequestrant-managed fillfill through a sediment cartridge; pool co. doses metal sequestrant metals low (< 0.3 ppm) $100–250 $100–200
B Fill-time filter skidsediment → oxidizing media (Katalox / greensand) inline on the fill line; slow fill by design metals moderate (0.3–2 ppm), plug-and-play preferred $900–2,500 $50–150
C Batch-treat in the tank we ownaerate to oxidize Fe/Mn → settle → draw from above the sediment; flush periodically metals moderate + tank has power & headroom; cheapest hardware $350–900 $0–50
D Permanent wellhead treatmentAIO air-injection + backwashing Katalox/Filox bed treating all well water metals high (> 2 ppm) or whole-property symptoms; set-and-forget $2,500–5,500 $50–150
E RO polish for pool fillor a mobile RO fill service per event only if TDS/CH extreme — rare; overkill for metals $1,500+ varies
F Blend with rainwaterfill mostly from RW tanks (near-zero minerals); dilution does the heavy lifting RW volume meaningful vs pool volume; pairs with any route $200–500 $0

GATE ①+②

Lab results in → pick the treatment route by the pre-registered thresholds, and lock the sourcing policy (pool ← well + blend; landscaping ← RW-first with well fallback is the recommended split — the counter-argument to well-first: full RW tanks overflow in the next storm, wasted free water, while the well refills itself).
