After you flush
Taking sewage away
Taking it, treating it – returning it to nature
We collect around 1,271 million litres of wastewater from three million households and 200,000 businesses, every day in the North West. When you flush it, pour it, pull the plug and drain it away, your wastewater goes on a journey back to nature – which starts the moment it leaves your property and enters our sewage system.
Collecting and treating sewage
Wastewater collected from homes and businesses is transported along 72,000 kilometres of pipes and sewers to over 560 wastewater treatment works, all dedicated to cleaning up in-coming wastewater so that the treated water can then return to rivers and to the sea.

Sewer flooding is unpleasant and distressing and we spend
money every year to help prevent it from happening.
There are many different reasons why a flood can occur and
the impact it has on our customers can vary. For these reasons we don't have a specific target to achieve a reduction in internal
sewer flooding but, instead, have developed an index which assesses the impact of sewer flooding on our customers. This index looks at the flooding of properties, outside
spaces and repeat flooding.
Unfortunately we didn't meet our index target for 2015/2016. We suffered from a significant amount of rainfall throughout the year which increased the number of internal flooding incidents in our region.
Over the next five years we're aiming to reduce our index score and
a help reduce the impact of sewer flooding
