Planning permission was granted on 25th October 2018 allowing Yorkshire Water to proceed with plans to relocate the Withernsea wwtw to a site near the village of Hollym. Yorkshire Water had previously announced on their website the initiation of planning for a new-construction Aero-Fac® 100% total wastewater treatment system servicing a nearly 15,000 population equivalent (pe) to replace the existing Withernsea WwTW.

This is what the Yorkshire Water web article had to say about the proposed project.

Withernsea Wastewater Treatment Works (WwTW) is located to the south of Withernsea, close to the village of Hollym. When it was last upgraded in 1991, it was 168 metres away from the cliff edge; however, due to significant levels of coastal erosion, the WwTW is now only around 40 metres from the cliff and needs to be relocated. In addition to a new sewage works, a new sewer will need to be laid to transfer flows from Withernsea to the new site, and a new sea outfall pipe will also be built next to the existing one. Since 2015, we’ve engaged with stakeholders and local residents on the long term solution, and on Tuesday 5th December (2017), we shared our revised plans for the treatment works with the community. The new Aero-Fac technology will be supplied by Gurney Environmental. The system is more sustainable and has a much lower carbon footprint as it uses little energy and is able to treat the wastewater to an excellent standard. Once planning permission is granted, then work is expected to start on the new treatment works in the Spring of 2020 and completed in the Summer of 2021.

Yorkshire Water’s John Bond went on to say: “Our proposal is a step away from traditional treatment works and means we are opting for a much greener, more environmentally friendly option. The new proposal means construction ties will be reduced, traffic movements can be minimised and once finished, the site will be virtually noise free. In addition, visual impacts and the risk of odour will be greatly reduced”.

Yorkshire Water’s Communications Advisor, John Bond continued: “Our existing facility in Hollym, near Withernsea needs to be replaced as it is now only 40 metres from the sea due to rapid coastal erosion in the area. By building a new treatment facility inland, we’re able to look at new, alternative options for treating the town's waste water, and we feel Gurney Environmental’s experience and track record provide us with the best solution for both ourselves and our customers for the future.”


We've already found that the ponds work a lot better, they are a lot cleaner and functionally look a lot better than what they were previously. It seems to be working at this stage, so we're quietly confident that it's going to be a good investment.

...there is no doubt about it, the ResMix system works! Having started with a volatile and inconsistent chlorine residuals in our supply, we are now using the WEARS product to mix and dose our tanks. We are not alone in our experiences here. All I can say is that the results speak for themselves.

Adding the Accel-o-Fac® system to South Gippsland Water treatment cells where traditional surface aeration was previously used allowed the corporation to significantly reduce energy use. The savings in kWh are excellent with one application saving 72% in energy compared to the previous year.

The fact that there is no associated sewage odours [with the Accel-o-Fac wwtp] meant that the system could be located relatively near to the village, and, after 10 years of use, no sludge removal has been needed.

These results show that the [ResMix] mixer is providing a fully mixed water column and preventing conditions for manganese and nutrient release from the sediments.

We are very pleased to be using this innovative management system in the reservoir at Pontsticill. This investment will improve the water quality for customers in the area and ensure they continue to receive a top quality supply of drinking water long into the future.

The Aero-Fac system at Windsor has to date met and exceeded our consent discharge levels, and we have been very happy with the system installed.
