We are a commercial real estate water advisory firm. We work with real estate portfolios to reduce infrastructure cost exposure — identifying billing errors, eliminating water waste, and converting every improvement into verified NOI gains and ESG performance data.
For the first time, portfolios of any size have access to AI-driven utility intelligence, real-time monitoring, and institutional-grade ESG reporting — without millions in capital outlay.
Simplifying the Business of Water
The latest on water costs, utility overcharging, and sustainability compliance — critical intelligence for your portfolio.
Evident Reduction. Evident Savings. Enhanced Property Value.
Trusted by forward-thinking owners and operators of hotels, multifamily properties, manufacturers, and commercial real estate portfolios.
A comprehensive water audit establishes asset-level baselines, identifies billing errors, unmetered losses, and mechanical inefficiencies — and delivers a prioritized roadmap with quantified ROI and payback periods. Detailed reporting structured for asset owners and investment committees.
More about our approach →Ara AI automates utility bill collection across every asset, closing data coverage gaps while IoT monitoring validates consumption in real time. The combined model produces the verified, audit-grade data that institutional portfolios require — without adding headcount.
Explore Ara AI platform →Star ratings are assigned by quintile position — not against absolute standards. WST manages both the WT1 coverage gap (Ara AI) and the performance gap (verified monitoring data) that determine where your fund ranks. We prepare your GRESB water submission from end to end.
Explore GRESB advisory →Consumption normalized by asset class, gross floor area, and occupancy type — benchmarked against verified peer data. Hospitality benchmarks differently than industrial. WST calibrates the comparison correctly so your investment committee is seeing an accurate picture.
Open benchmarking tools →Self-funded equipment ownership delivers substantially more long-term value than partner-funded models because Section 179 deductions apply only when clients own equipment directly. WST models every financing scenario — tax savings, payback, and NOI impact — before any capital is deployed.
Explore tax strategy →WST coordinates directly with licensed mechanical and plumbing contractors for equipment installation — high-efficiency fixtures, flow management devices, cooling tower upgrades, and IoT sensor networks. Every installation is followed by a verification audit to document actual consumption reductions.
Explore smart monitoring →Request a confidential water assessment to identify cost exposure, ESG data gaps, and the risk mitigation and financial impact of a structured water programme across your portfolio.
