Denmead Green, Hambledon Road, Denmead PO7 6NU | Off: 24/06/2026 09:00 | Planned maintenance
We will be undertaking essential maintenance work on the water distribution network which will mean customers' water supplies will be turned off for a maximum period of 7hours on 24 June 2026 commencing at 09:00
Prior to the water supply interruption, we suggest that you draw off and store sufficient tap water for your drinking needs over this period. If your property has a cold-water cistern, it should provide sufficient reserve for your normal sanitary requirements (i.e. lavatory flushing) if used sensibly. Central Heating systems should not be affected by the shutdown.
Slight discoloration of the water may occur when the supply is restored so we would recommend checking that the water is clear before using washing machines or other appliances. We would in any case advise that water using appliances (washing machines, dishwashers etc.) should NOT be used during the shutdown period.
If you do experience any discolouration of the water supply, this is normal following such events and poses no health risk to the water supply system. To address this, we would recommend you run your cold kitchen tap for 10 minutes or until clear. For further guidance about this, please refer to our water quality information page at portsmouthwater.co.uk/water-quality/
We apologise for any noise or inconvenience that our activities may cause you but we will endeavour to keep this to a minimum and thank you for your patience whilst we undertake these essential works.
If your water supply does not return to normal after we restore the supply, please contact us on 023 9247 7999. Our staff are available on this number 24 hrs a day to provide further advice or if necessary, arrange for a company representative or plumber to call. They will rectify any problem which is found to be due to this interruption to supply, free of charge.

We are aware that some of our customers in the area above may be experiencing a loss of supply or low water pressure. This is due to a burst water main in Nerissa Close affecting the water pressures in the area. We have a team on site undertaking emergency repairs and are working hard to restore supplies as soon as possible.
This post will be updated as more information becomes available.
We are sorry for any disruption or inconvenience this matter is causing and thank you for your patience.
