Newtown's recycling centre is being sanitised hourly, according to Powys County Council.
The site, along with Welshpool's and others in the county, were opened last week following closure during the Coronavirus lockdown.
People have restricted to 10 minutes for each visit, social distancing rules were to apply and the council had stressed visits should be for “essential” use only.
At the Economy, Residents, Communities and Governance scrutiny committee meeting, its Chairman, Councillor Mathew Dorrance, asked about the hourly cleaning procedures at the sites.
Cllr Dorrance said: “The risk assessments flagged that catching and spreading the virus at recycling centres was high risk when they opened.
“To mitigate this, control measures such as disinfecting hand rails on gantries and handles on doors, is done hourly.
“What assurances do we have that this is being carried out?”
Senior manager for waste and recycling, Ashley Collins, said: “We’ve been having regular meetings with Potters to make sure everything is in place.
“We’ve got our own staff on site doing the traffic management, they are also in the site as well so they can see what’s going on.”
Mr Collins added that Potters have a health and safety manager checking up on the sites.
He also said that it was in their staff’s “own interest” to make sure that cleaning takes place, but he could not, “guarantee” this.
Cllr Dorrance, raised concerns about sanitising the sites, and said he expected there to be a checklist for staff to follow at each site.
Director or economy and environment, Nigel Brinn, said: “It’s a fair point it’s something to pick up with the contractor.”
After the meeting councillors were told that Potters had confirmed that sanitising is being done hourly.
They keep records of this that are available for inspection.
