(1) 
For any public utility such as water service, sanitary service, electric or gas, the maintenance by the utility authority or company shall extend to the limit of a public right-of-way line or public easement line or a shutoff valve or terminal connecting manhole or other similar private line connection point, unless otherwise regulated in the utility owner's rates, rules and regulations, or other specific ordinances or agreements either currently in effect or which may be approved in the future.
