Chelwood Gate - flushing to protect water quality
07 February 2017

Work is being carried out to clean water mains in Chelwood Gate, East Sussex to safeguard the quality of drinking water.
It is part of maintenance on South East Water’s underground mains.

What is flushing?
Flushing allows naturally occurring harmless deposits inside the network – such as iron or manganese – to be removed.  While these naturally-occurring deposits are not harmful, they can temporarily discolour the water.

Why do we use this method?
Flushing the water mains from the start to finish of the network – from service reservoirs, which store fully treated drinking water, to the point at which it supplies customers – is a very effective way of cleaning the inside of water mains.

How is flushing carried out?
Flushing involves directing water through the pipes quickly to draw the sediment deposits –out of the network.
 Once the water reaches its journey’s end, the flushed water containing these deposits is directed into the drains.

Is flushing the only way it can be done?
We are careful to only use the amount of water needed to clean the pipes and flushing stops as soon as the whole system is running clear.

Will flushing affect my water supply?
During the flushing process customers may notice a reduction in water pressure, and possibly some discolouration, but this is temporary and can be solved by running the kitchen tap until the water runs clear.
