We need your help to reduce customer demand for water in Kent 

 

Good afternoon

We’re seeing sustained, very high demand for drinking water across our supply areas. Demand has now topped the June average for 16 days in a row, with a peak of 680 million litres of water being supplied yesterday alone. This was the highest we have seen in years, and we need your help to keep it down.

What will happen as a result of continued high demand?

This unprecedented level of demand is surpassing that of 2022 and 2023, and is causing our drinking water storage tanks to run low across our supply regions. 

We’ve started to see localised issues with customers experiencing low pressure and supply interruptions as a result, with some affected yesterday during the peak evening demand. We were able to restore supplies overnight and into the morning, but should high demand continue today, we may see customers experiencing localised supply issues again this evening.

What have we been doing?

To keep customers in supply during this time, we’ve been continually monitoring the network and using our fleet of tankers to keep our drinking water storage tanks topped up. Where customers have experienced supply interruptions, we have provided bottled water. 

However, the impact of sustained high demand has caused widespread low levels of storage and demand in some areas may now outstrip our ability to treat, pump and supply water to our customers’ taps.

We’re asking for your help

With high temperatures again today, we’re writing to all of our customers to ask them to Stop, Think and Act to use water wisely. 

  • Stop watering the garden using fresh water from the outside tap. Water from baths, showers and sinks can all be reused instead. 
  • Think, is this task really essential? Letting the lawn go golden is perfectly fine, they’re naturally designed to bounce back when it rains again.
  • Act now, please continue to do all you can to cut your water use down.

As a key stakeholder, we’re asking you to share this message across your networks and within your communities, to help encourage everyone to be mindful of their water use and keep demand low to allow local storage tanks to recover. 

 

 

Kind regards
