Multiple noisy / clanking manhole covers in road

Following recents works to Ty Draw Road related to the new development further up the road, several manhole covers have been laid in the road. This report concerns those just south of Ty Draw House (pin on map shows approximate location on Ty Draw Road). It appears that at least one, but seemingly several of the manhole covers are wobbly and therefore make a loud noise as vehicles drive over them. As traffic flow has increased on the road, this now happens frequently throughout the day and the loud clanking disrupts the previously peaceful character of the area and is causing a nuisance. Please can these manholes be checked and adjusted so that they are not able to noisily clank. I assume as they have recently been fitted (i.e. within the last 12 months) that a defect check will be possible. Many thanks
