Space requirements for sewerage construction and maintenance

A: This refers to back alley space required for carrying out user construction work; for single-side connection, a drawback of 75cm from the boundary line is required; for double-sided connection, 75cm each is required for either side residents, a total of 150cm. This requirement is for the construction work as well as for pipeline cleaning and maintenance works in the future.
