The covers in Thessaloniki are made of metal
, and their shape is square
, round
, or rectangular
.
Sometimes round covers intended for sidewalks are surrounded by a square frame, which greatly facilitates the paving work around them
.
No colored or gilded covers were found in the city. No covers bearing the city emblem were found either.
The purpose of the covers is usually determined by the name of the utility: ΟΑΘ - sewage (Thessaloniki Sewerage Authority), the telecommunications provider OTE
, etc.
The utility companies are indicated on most covers: EYATH (or by its former name ΟΑΘ - the sewerage corporation)
, the Municipality of Thessaloniki
, or the telecommunications organization OTE
