statement from wessex waterRead Now
Wessex Water have sent us this statement about their plans for storm overflows. Note especially the section on rainwater separation:
I’m writing to you to explain more about what we’re doing to improve river and coastal water quality in the area, and our plans to address storm overflows. We know many of our customers are concerned about overflows, and we’re absolutely clear that they aren’t fit for the 21st century. Our long-term aim is eliminate the need for storm overflows.
There are probably certain questions you’re frequently being asked about ‘sewage dumping’, or indeed may have questions yourself. I thought it would be helpful to outline what we’re doing about storm overflows, now and in the future, as part of our commitment to great river and coastal water quality in our region.
Wessex Water does not ‘dump’ sewage anywhere. Storm overflows operate automatically during or after intense rainfall to prevent flooding of properties and are licensed by the Environment Agency.
We would love to stop all storm overflow discharges immediately. But they are a legacy resulting from how houses and drains have been built for over 150 years – being drained by one pipe to carry both rainwater and sewage.
To tackle the issue, we’re spending £3 million every month on improving them and reducing how often they operate. We’re also planning to go even further and, if approved by our regulators, will invest around £9 million per month from 2025.
We feel it’s important people know where and how often storm overflows operate. You can view a map of all our overflows, see the primary cause of their operation and our progress in installing real-time monitoring on our Drainage and Wastewater Management Plan portal. You can also download the number and hours of overflow discharges and what we’re planning to do about them from the performance section.
What we’re doing now
Here are some examples of the different ways we are investing to reduce overflow impact and discharges.
Increasing treatment capacity
At treatment centres means we can deal with more rainwater after a heavy rainfall event. One location where we’ll be doing this is our largest water recycling centre in Avonmouth, near Bristol.
Increasing storage capacity
By installing large storm tanks we are able to store more rainwater and sewage prior to it being treated. An example of where we have carried out this work is at Compton Bassett in Wiltshire.
Separating rainwater from sewage
This approach is the most environmentally friendly solution, and one area where we have done this is at Portland, in Dorset, which has seen surface water from 8,000m2 area removed from the combined system that also carries foul water.
In more rural locations, nature-based solutions can be used like reed beds to naturally treat storm water before it’s discharged into local watercourses. We have successfully achieved this at Shrewton, Wiltshire where groundwater at times inundates the sewer network.
Our Storm Overflow Improvement Map outlines where and how we’re tackling the issue near you.
What we all can do
The best solution is separating rainwater at source so it doesn’t enter sewers. We all need to value rain as a resource, capturing it locally for reuse (such as garden watering) and then disposing of it back into the environment as close to where it landed in the first place, for example, via rainwater gardens and/or soakaways.
