Summary

A request was made for three years of detailed sewage discharge and defect statistics for Peel Bay, but the authority only provided defect data and partial flow records starting from 2022 due to data format limitations and server failures.

Key Facts

Manx Utilities does not hold the requested data for the full three-year period as some records only date back to 2022.
The Peel Promenade pumping station is automated to pump only during ebbing tides during the bathing season.
Tide data is supplied by the National Oceanography Centre and interpreted via industry-specific software.
Hourly flow data is incomplete due to a failure of the historian server.
Information regarding defects in the Peel pumping station and sewer network for the last three years was provided.

Original Request

MAY TO SEPTEMBER: I am told during this time over a size of an Olympic size swimming pool is pushed into Peel Bay 2,900 cubic meters on the ebbing tide which is twice a day.

Number of reported sewerage issues raised (date if issue, description of issue, cause and resolution)
Number of times sewage has been emptied NOT on an ebbing tide (date, time, reason and amount of sewage, tide type, i.e. ebbing or not

OCTOBER TO APRIL: I am told during this time that sewage is only emptied when the storage facility is full
