We're continuing to chlorinate until 3 July and we've delayed the second round until 22 to 25 July. 

Some of work on the new Headingly Lane pipe involves cutting into the trunk main and so chlorination is needed ensure the water always remains safe to drink. 

Customers who will be affected by outages have already been notified.

Information for fish owners

The chlorine level during this time will be quite low- about 0.3 mg/l leaving the plant (normal dose is 1mg/l). If you have fish in tanks, you should de-chlorinate the water before topping up tanks. 

Also, please note that on 16 July, due to a trunk main shut down, water will supplied solely from our Richmond source during the day. This source has a higher nitrate level (about 50mg/l). We recommend that you do not change the water in your fish tank during this period as a sudden change in nitrate level can be a shock to fish (the normal level is about 24mg/l).

These dates may be subject to change, as the work is weather dependant. Please check the website and social media for updates.


  • If you have fish - don’t forget to use a neutralising agent, if you change any water in the tank (this is available from pet stores).
  • Using a carbon filter can remove the chlorine taste
  • Chilling the water in the fridge first and drinking it cold will also make it taste nicer
