Thames Water Open Data

About Thames Water Open Data

Thames Water Open Data is an API portal providing programmatic access to open data from Thames Water Utilities Limited. Available resources include the Discharge To Environment (DTE) endpoints, which give historical and current statuses of storm discharge activities, and the Acoustic Logger Data endpoint, which offers acoustic logger sensor waveform files and associated metadata. Responses are returned as JSON, with a common metadata block and support for filtering, pagination, and comparison operators (greater-than, less-than, equals, not-equals, and their inclusive variants) across query parameters.

The portal is intended for developers and researchers working with environmental data and water infrastructure monitoring. API access requires signing in or registering, and use is governed by published terms of service. Requests are limited to 5 per second per user, with per-endpoint response limits (up to 1000 records).

A newer version of the APIs is being launched on a separate portal that removes the registration requirement, and migrating to it will involve breaking changes to the URL and API behavior compared to the current version described here.
