Saltend Waste Water Treatment Works – “Impressive – but we are watching you!”

THEY MAY look like giant recycling bins, but these are the component parts of the new £3.5m Odour Control Unit at the Waste Water Treatment Works at Saltend.

The Hedon Blog was invited to tour the site yesterday and see the construction work taking place of the new unit that is designed to “significantly reduce” odours from Saltend.

Following being treated by the existing odour control unit then the liquid waste products will be treated once again by the new unit. The larger tanks contain pumice stone, and bacteria in the rocks ‘eat’ the hydrogen sulphide which, Yorkshire Water’s Matt Thompson explained, is the chemical compound that creates the ‘rotten eggs’ odour. The resulting liquid is then blown through the smaller tanks which are filled with bacteria-infused sand. Essentially, the process should reduce odours.

Yorkshire Water's Matt Thompson shows the raw sewage that comes into the site - and the resulting clean water

Yorkshire Water hosted a series of visits to its Saltend site yesterday in renewed efforts to explain the useful role that the facility plays in turning raw sewage into harmless water (albeit yellow coloured) that can be pumped back into the River Humber. It was an opportunity for the media to ask questions about the site and the multi-million pound investment into reducing odours.

The Hedon Blog took anti-smells campaigner Jo Gardner and her son Zak with us to see the facility for themselves. We asked Jo what she thought about the visit:

“It was very impressive to see how the site works – but we need to know that it will eliminate odours. The campaign will continue and Yorkshire Water knows that we are watching them!”

12-year old Zak said: “It was really cool! But it really smelled there!”

The point of conflict between Yorkshire Water and local campaigners is over the frequently used term to describe the water company’s aims, which is: “to significantly reduce odours.”  Campaigners want to see the elimination of odours from the site. The proof of the case will be in how significant the reduction of odour problems will be in practice.

The new odour control unit is expected to become operational in December 2011.

  1. I will believe it when I see it (or don’t smell it!) YW promised us that the plant wouldn’t smell – in fact they said it *couldn’t* emit smells – before it was built, presumably in order to get planning permission. We all know now just how truthful THAT statement was! As I said, I remain unconvinced. I would LOVE to have to eat my words, but somehow…….
