How does a manhole cover become electrified?
The risk of electrocution occurs when metal manhole covers exist in combination with charged wires (usually related to traffic signals or tramways) and water – think rain. These at-risk covers are 'insulated' from the surrounding earth by concrete or other materials which may allow for electrification.Mar 12, 2019

Why do I have two manholes?
Manholes: if you have double the number of manhole covers it is more than likely that you have a dual drainage system which carries soil and waste water. Property age: newer properties build after around 1970 will have a dual drainage system. Older homes can have separate pipes for soil and waste.
