This Event Duration Monitoring (EDM) dataset relates to the performance of storm overflows in England. Water and Sewerage Companies (WaSC) submit this data to the Environment Agency each year as part of the Bathing Season Return, in order to fulfil their permitted conditions to discharge from these storm overflows under the Environmental Permitting Regulations. Data files are provided by year and, where applicable, include a separate sheet for each WaSC with storm overflows in England. Each WaSC sheet shows how often and for how long each monitored storm overflow discharged during the EDM Bathing Season (1 May – 30 September). The dataset also explains why EDM may have provided information for less than 90% of the relevant return period, and why an overflow may have high spill counts during that time. These datasets reflect the best information available to the WaSC at the time of submission. The datasets from 2023 onwards also include key summary data tables. These summary tables provide information such as the number of storm overflows with EDM, the number returning spill counts, and the average spill duration and average spill count for each WaSC.

Our letter to water companies strongly encouraged them to proactively disclose information relating to sewage discharges each month, and we are reiterating this call today. Publishing sewage discharge data proactively means that the public have access to the information they need, when they need it. If this information is publicly available, it may also be more efficient by reducing individual EIR requests in the future for the same information. So far, only two water companies, Yorkshire Water and South West Water, have committed to publishing this information each month. This is disappointing and brings further into question the commitment by the sector to being open with the public. We've heard from several water companies who argued that publishing this data was too challenging, despite these firms already collecting data on start and stop times due to a legal requirement to report to environmental regulators.
Water companies in England, Wales, and Northern Ireland haven't been very responsive to the ICO's call for proactive publication of monthly sewage discharge data ico.org.uk/about-the-ic... post from the Information Commissioner's Office

Honiton and Sidmouth MP Richard Foord has called for "one reliable source of data" on sewage spills after claiming that South West Water's live information can differ from that of a national body. Mr Foord, a Liberal Democrat, claims SWW’s Waterfit Live map is "not entirely transparent" because of the way it reports data, suggesting that there had been discrepancies between it and Water UK's National Storm Overflow Hub. However, SWW has said its WaterFit Live platform shares "near real-time data" on storm overflows and that it is the "same data used on the National Storm Overflow Hub".

The Environment Agency has analysed Event Duration Monitoring (EDM) data on storm overflows associated with bathing waters across England for 2024. This regulatory data, bolstered as 100% of storm overflows are now fitted with event duration monitors, is a vital tool for us to plan what investigation and improvement work from water companies needs to take place, and to work with water companies and local partners to take action where needed. The EDM data we receive from water companies for the bathing season (May to September inclusive) are a sub-set of the EDM Annual Return data for all storm overflows, which is published by the Environment Agency each March.
