This Dashboard shows data for Thames Water Sewage Treatment Works in the whole of the West Berkshire Council area
The STW sites are listed from west to east. All discharge data is pulled from the Thames Water API portal and stored in the PVFF database from which this webpage is generated. The groundwater and rain data is pulled from the Environment Agency data API into the PVFF database. You can also link to Thames Water's own STW discharge map.

The data issued from the Thames Water API portal records a status change. A status change alert type can 'Start', 'Stop', 'Offline Start', 'Offline Stop'. If a site has issued a 'Start', the analysis below assumes that the site continues to discharge until a 'Stop' alert is issued, even if a 'Offline Start' or 'Offline Stop' has been issued in the meantime. Similarly, if a 'Offline Start' has been issued when the site is not discharging, we have considered it to remain not discharging until a 'Start' alert is issued.
