WaterGod produces longitudinal, standardised Water Exposure Scores for individual properties. No institution has the access or the mandate to test inside your home. The only way to build this dataset is household by household.
The Independent Water Commission's Cunliffe Review (July 2025) identified data transparency failure as a systemic weakness in UK water regulation. Statutory monitoring operates at treatment works level. It tells you what leaves the plant, not what arrives at your tap. The gap between the two is where lead pipes, ageing infrastructure, and local contamination sit unmonitored.
River monitoring citizen science exists. Utility-side sensors exist. One-off test kits exist. Nobody is building independent, household-level, longitudinal exposure timelines that are standardised, versioned, and comparable over time. This data has to be built from the bottom up, because no institution has the access or the mandate to test inside people's homes. WaterGod is building that infrastructure.
Every WaterGod test produces a Water Exposure Score: a standardised, versioned composite index that translates raw parameter readings into a single, contextualised number. The WES is not a safety certification. It tells you where your water exposure sits relative to regulatory thresholds, historical baselines, and other properties in your area, and whether that position is changing over time.
| Score | What it represents | Access |
|---|---|---|
| HWES | Household Water Exposure Score. Your home's individual exposure profile, based on direct testing. Updated with each re-test. | £20 test + subscription |
| CWES | Commercial Water Exposure Score. Same core methodology applied to business and sole trader properties. | £20 test + subscription |
| AWES | Area Water Exposure Score. Aggregate exposure picture for a local area, combining HWES/CWES data with public environmental data. | Free via the WaterGod Map |
WaterGod provides standardised exposure scoring. We do not diagnose health outcomes, certify water safety, or prescribe action. This bounded positioning is deliberate: it is what allows institutions to reference the score without liability concern.
WaterGod's scoring design is informed by multiple rounds of user research: concept validation interviews in December 2025 and in-home field testing with actual water quality tests in the New Forest area in February 2026. Together these provide both conceptual and operational evidence for scoring and product decisions.
WaterGod currently uses specialist portable equipment to conduct in-home water quality tests across 13 parameters, producing quantitative readings that feed directly into the WES. This is screening infrastructure: it identifies where exposure sits, flags readings that warrant further investigation, and provides clear next steps when concern is indicated.
Our R&D programme is focused on reducing per-test cost to enable watershed-scale density through electrochemical sensor technology and smartphone-based reading. We are actively building academic partnerships in sensor science and environmental data methodology to accelerate this pathway.
The WaterGod Map aggregates independent testing data with publicly available environmental data into a single interface. It has standalone value from day one, before WaterGod's own testing density reaches critical mass, because it brings together data that currently sits scattered and inaccessible across government agencies, water companies, and regulatory bodies.
As household testing density grows, the WaterGod Testing Layer becomes the Map's unique differentiator: the only source of independent, property-level, longitudinal water exposure data at this resolution.
Every household that tests contributes to the Area Water Exposure Score. Individual action compounds into collective visibility. The more households that participate, the more credible the scores, and the harder it becomes for contamination or infrastructure failure to go unnoticed.
WaterGod's pilot target is 1,000 households tested within 12 months, building watershed-scale density in the New Forest and expanding to adjacent areas. Southern Water has expressed interest in the data WaterGod's household testing programme would produce, particularly its potential to support resilience planning and PR24 performance commitments around lead pipe identification and customer experience.
We are applying for the Ofwat Water Discovery Challenge 2 (deadline 8 April 2026) to fund the pilot and accelerate R&D. WDC2 awards up to £100,000 for finalists and up to £550,000 for winners.
WaterGod is building academic partnerships to advance two capabilities: electrochemical sensor development for low-cost lead detection, and environmental data methodology for standardised exposure scoring. If your research intersects with either, we'd welcome a conversation.
