Condominium associations carry water costs in two categories that are both difficult to manage without systematic support: common area and amenity water (pools, irrigation, fitness, mechanical) and the administrative complexity of sub-meter billing across dozens or hundreds of residential units. WST audits both.
The Challenge
HOA boards manage condominium water costs through budget approval rather than systematic audit — which means billing errors and operational waste in common area systems persist for years without being identified.
Condominium pools are typically filled on a fixed timer or manual top-up schedule that doesn't account for actual evaporation rates, splash losses, or backwash volume. A pool manager adding 500 gallons per day on a fixed schedule in a low-evaporation week is wasting 200–300 gallons per day. Across a year, over-filling accounts for 20–35% of pool water consumption — a category that WST's monitoring and level-sensor installation addresses directly.
Condominium common area irrigation systems are typically programmed at installation and never revisited. As landscaping matures, original species selections age out, and local water restrictions change, the original schedule becomes increasingly inappropriate. Most associations have no monitoring on irrigation supply — making it impossible to identify malfunctioning zones, seasonal over-watering, or head failures that can waste millions of gallons annually.
In condominiums with individual unit sub-meters, common area water (amenities, mechanical rooms, irrigation, pool) is typically funded through HOA fees. But the HOA's common area water bill is rarely audited against the sub-meter totals — a gap that means billing errors in the master account are invisible to the board and chronic common-area overcharges are simply absorbed into annual assessments.
WST Approach
