Subject: Storm overflow UUP00748 on the River Mersey via SW Sewer: request for information

Dear United Utilities,

I am writing about storm overflow UUP00748 on the River Mersey via SW Sewer.

Environment Agency storm overflow monitoring data for overflow UUP00748 on the River Mersey via SW Sewer (operator listed as United Utilities) records no spill events starting between 18 September 2026 and 18 October 2026.

As of 18 October 2026 at 02:14 UTC, the monitor for this overflow is reported as offline (status timestamp in the public data: 24 June 2026 at 13:33 UTC). While a monitor is reported offline, the public data cannot show whether the overflow is spilling.

Further details from the public record:
- Open automated data flags on River Truth for this overflow: 1 (comparisons between public datasets, not findings of fault)
- On the River Mersey, per the OS Open Rivers network (Ordnance Survey, Open Government Licence)
- Location: 53.44082, -2.38550
- Sources: Environment Agency National Storm Overflow Hub and Water Quality Archive (Open Government Licence v3.0), cross-referenced via River Truth (https://rivertruth.co.uk/overflow/11474)

These figures are taken from public monitoring data as published and may be revised by the publisher. They are not a finding that any permit condition has been breached.

[Add your personal context here, for example how you use this stretch of water.]

Please could you tell me:
1. Whether the monitoring record summarised above is accurate and complete
2. Why the monitor is reported as offline and when it is expected to report again
3. What work, if any, is planned at this overflow, and on what timeline
4. What measures are in place to reduce spills from this overflow in future

[Delete if not applicable: I have copied the Environment Agency, Ofwat and my MP into this correspondence.]

Yours faithfully,
