An undesirable stink wafting across the city is not caused by delays to improving the Chester Wastewater Treatment Works, insist Welsh Water.

Over the past few days residents have reported smelling the disgusting odour which has spread throughout Chester, Blacon and Hoole – and even been smelt outside the Countess of Chester and Chester Business Park.

The unsavoury pong comes as we reveal that work to finally banish the Sealand ‘Stink’ has experienced delays, and now will not be complete until November – one month later than originally promised.

But Welsh Water, who pledged £1M to fix the stench which has plagued the lives of residents living close to the Wastewater Treatment Works, insist that they have not caused the smell which is reportedly spreading throughout the city.

The company is currently working to improve the ‘sludge processes’ at the treatment works, and say they are not aware of any odours caused by plant.

One resident, who lives in the Garden Quarter, told The Chronicle the smell was getting so bad she couldn't bear to sleep with her windows open, as the smell kept her awake and was impossible to get rid of from her flat.

While other residents have taken to Facebook and Twitter to vent their frustrations, and wonder where the smell, which is described as like ‘cow manure’, is coming from.

One disgruntled resident tweeted in response to calls for an official statement from Cheshire West and Chester Council, “The smell in Hoole is making me sick! Anyone going to take responsibility?”.

Another vented: “What is that smell? I can’t go outside or have the door open! It’s so nauseating!”

Last year homes and businesses across Chester and Deeside were plagued by the pong, which was believed to be caused by the spreading of chicken manure on fields surrounding Sealand Road, and affected residents in Chester, Garden City and Connah’s Quay.

Meanwhile Welsh Water say they are not responsible for the odours and are continuing work on improving the Wastewater Treatment Works, despite delays due to ‘design’ problems.

A spokesperson for Welsh Water said: “Welsh Water is investing £1m on a scheme which will improve the performance of its Chester Wastewater Treatment Works.

“We started work on site during mid-August, which was slightly later than originally planned due to us having to refine the design of the work.

“This phase of work is set to be completed in November.

“Our work has not impacted on the operation of the treatment works and we are not aware of any odour issues in the area in recent days which are linked to the treatment works.”

A spokesperson for Cheshire West and Chester Council said: "We have been advised by the Environment Agency that there are permitted contractors in the area who may be spreading sludge water, which we believe is the source of the odour."

Members of the public can reports incidents of agricultural odours to the Environment Agency incident line on 0800 807060 or to the CPI Environmental Health  on 0300 123 7038.
