Horsley Water Treatment Works Upgrade

A £46M project to upgrade Horsley WTW has now reached a key milestone. We have selected our partner Mott MacDonald Bentley (MMB), to upgrade the treatment works.

Update by Joan Tatters

Good Afternoon,

This afternoon I will be dropping in a letter to the village residents regarding a temporary change to our working arrangements for a few days. 

Please see a copy of the letter:-

Dear Customer
 Work at Horsley Water Treatment Works
We are carrying out essential works at our Horsley Water Treatment works site. This is to ensure we continue to provide drinking water to our customers across the region. 
In order to complete this work we will be working on evenings and overnight into the early part of next week.  
During this work you may notice an increase in activity, some low-level background noise and temporary lighting in land to the south of the treatment works during these times.
We will do everything we can to minimise any disruption to you and please be assured that no additional vehicles will be passing through the village.
The works we are carrying out are essential and a priority for us and we will be doing all we can to complete this as quickly as possible. 

I would like to take this opportunity to thank you for your support and if you do have any concerns or wish to speak to us about the work then please telephone our customer contact centre on 03457 171100 or tweet us @nwater_care. You can also find out more information at and follow the link to the Horsley page. 

Yours sincerely 

Mike Forster
