No water / low pressure

Last updated.

Good news, we're all done in Rookwood Gardens and your water supply should be back to normal.

If your water is cloudy, don't worry - it's safe to drink. It's best to run your cold kitchen tap for a few minutes once your water is back on.

High demand for water during heatwave in Slough

Last updated.

The hot weather means we’re seeing a huge increase in demand for water across our entire area.

We’re currently supplying customers with an additional 450 million litres every day – this is 17% more than normal.

We are sorry to those customers who have experienced low pressure in SL postcodes over the weekend and into this morning. We’re working hard to increase the pressure in this area, wherever possible.

The hot weather means we’re seeing a huge increase in demand for water across our entire area. As a result of the amount of water being used, some areas are experiencing low water pressure – particularly at peak times. This is because water cannot travel around the network quickly enough.

Over the last few days, we’ve seen the highest ever water usage across Slough, Wycombe and Aylesbury. We’re doing everything we can to meet this extra demand, but we need your help.

We’re asking all our customers to save as much water as possible. This includes not using hoses or sprinklers so there is enough to go around and keep water coming out of everyone’s taps.

Low Pressure

We’ve been working very hard over the last few days to improve supply resilience in the Guildford area. The situation has started to improve and all customers should now be back in supply.


Whilst the weather remains hot and dry, we still need your help by continuing to use water wisely and keeping the level of demand down.
