Dad of three Usman Nazir said he was ‘horrified’ after making the disgusting discovery at the pool – and claims staff poured hot water on the waste to wash it away.
He said: “People need to be aware of the risks their children are being exposed to.
“I was horrified. I took a pic and informed staff at the time but nothing was done for nearly two hours.
"When somebody did come, they poured hot water and walked away, leaving faecal residue all over the sink and children were using it.”
Mr Nazir, who has three children aged seven, five and four, took a picture of the poo in a sink in a cubicle at the leisure centre and shared it to the Ponds Forge Facebook page.
He posted: “I do apologise in advance because the picture I am going to post is gross.
“While I understand this is not the centre’s fault somebody pooped in the sink, what alarms me the most is how the matter was handled and the length of time it took for them to take care of the issue and not cleaning using the relevant chemicals.
“SIV is making thousands of pounds and can’t keep our children safe from serious health hazards.
“It’s appalling. I have spoken to the manager and it appears very little was done as the following week we found blood on the floor which again was there for several hours before being cleaned up.
“It clearly suggests regular audits of the changing areas are not being undertaken.”
In response, Ponds Forge refuted the claims over the length of time and the steps taken to clean the cubicle.
Ian Hamilton, general manager of Ponds Forge, said: “I can confirm that our staff were alerted to human faeces in a sink in the male changing room by a customer. The matter was removed immediately and flushed away by a member of staff and then the area was thoroughly cleaned using the relevant chemicals.
“Any insinuation that the sink was just rinsed with water is insulting to the staff who dealt with the matter professionally.
“Unfortunately, our cleaning staff do have to deal with situations such as this and I’m sure most people would agree that the actions of the individual responsible were disgusting.”
