SANEAMIENTO LEVE E SUSTENTÁVEL

Korumin is a product name of the manufacturer PAm (possibly only in South America, in any case this product description is found on the manufacturer’s website in Brazil, where the text at the bottom of the lid also appears, so it is likely that this text appears on all lids of the same type, and therefore the lid was not classified as a sewer lid)

The lid is similar to another manhole cover made by the same manufacturer Click for cover's details
