People in Onchan and Willaston may notice distruption to their water supplies from tomorrow (Monday).
The Island's Water and Sewerage Authority is completing flushing exercises every evening from Monday to Thursday.
The work may cause low water supply, low water pressure and discolouration of tap water.
The authority has advised the public to fill up kettles and buckets prior to the flushes so they have usable water for the morning.
