We’re investing £5.5 million on a major upgrade of Portswood Wastewater Treatment Works in Portswood, Southampton.
The improvements we’re making will help reduce odours in and around the site and will improve the efficiency of our treatment works.
Find out what progress we’ve made and what work is coming up:
Progress has continued throughout the week, with upgrade works taking place on a number of different treatment processes. A crane will arrive on site on Tuesday 19 June, to assist with installing necessary equipment.
With both consolidation tank lids recently installed, we’re confident this has helped reduce smells on site.
Looking ahead, we’re on track for our permanent filtration system to be installed this month and we remain hopeful it will be fully operational by the end of August 2018. The new system takes away the air from the covered tanks and will remove the unpleasant smells.
The temporary centrifuge will continue to be used on certain days and we’re aware it can contribute to unpleasant odours coming from site. We’ll continue to minimise the smells as much as we can, with odour reducing sprays just one of the additional measures in place.
We’ve continued to make good progress this week and the second consolidation tank cover was installed on Wednesday 6 June. Both covers are now in place, which should help contain odours and reduce smells on site.
The temporary centrifuge remains in use on certain days and we’re aware it can contribute to unpleasant odours coming from site. We’ll continue to do all we can to minimise the smells and the odour reducing sprays will remain in use for the time being.
We’re hopeful that our permanent filtration system that takes away the air from the covered tanks and removes the unpleasant smells will be installed this month and will be fully operational by the end of August 2018.
Thank you to those who joined us this week at our public drop-in. Our project team enjoyed providing you with the latest site updates and answering your questions.
The project continues to progress well with the first of the permanent covers for the consolidation tanks being lifted into place today. Preparations for the placing of the second cover are underway and we plan to have this in place by mid-June.
We’re aware the site can produce unpleasant smells, we’re doing all we can to keep these to a minimum while we complete the work. The temporary odour management will remind in place until we complete the improvements. We should be finished by the end of August 2018.
Want to know more about what we’re doing, come and meet the team:
We’d love you to meet our project team for an update and to ask questions about the improvements, so join us on Tuesday 5 June, any time between 1.30pm-3.30pm, for a public drop-in. We’ll be at Wessex DriveAbility, Leornain House, Kent Road, Portswood, Southampton, SO17 2LJ.

We've continued to put additional odour mitigation measures in place throughout this week.
The permanent consolidation tank lids have arrived on site and the first lid will be put in place during the first week of June. The second lid will be in place mid-June. These lids will help reduce the odours on site.
Additional odour mitigation sprays have also been put around the site.
We're working hard to make improvements that will reduce smells coming from the site in the future and we thank you for your patience.

Due to the warm weather we’re putting in place some additional odour control on the site. This will include installing temporary covers on the open consolidation tanks and installing additional odour management equipment.
The consolidation tanks will have permanent covers installed as part of the current improvements underway on site.
Please be assured we're working hard to make improvements that will reduce smells coming from the site in the future.
We have now completed around 20% of the odour control work. The next stage will be to install odour covers on the consolidation tanks, which will take place over the spring and summer 2018. The odour control system will be delivered in the coming weeks and work continues to replace the main control centre, with the installation of a kiosk and replacement of cables. Work to install jet cleaners on the storm tanks is also in progress.
New odour control covers have been installed over the inlet works – where wastewater enters to site for treatment. Final detailed design has also been finalised.
With work well underway, we’ve joined forces with contractors Galliford Try to fund a £5,000 community grant. The money has been shared between a range of local groups and organisations including Victory Gospel Church’s Recovered 4 Life project, the Friends of Portswood Rec and Southampton Mencap.
We’re finalising plans for two innovative new domes which will replace covers on two of the sludge consolidation tanks. The lightweight design of the domes reduces the health and safety risk for construction worker yet provides an efficient barrier for odours.
