No. Each system performs a separate function and is maintained by different agencies or companies:
Drainage lines/ditches carry rainwater away from your property and are typically maintained by Parish Drainage Departments.
Water lines carry potable water from a municipal or private source to your home and are operated by the owner of that water utility.
Sewer lines carry all toilet, sink, tub, shower and wash water from your home, via gravity collection lines and lift stations, to the treatment facility, where a mechanical treatment plant or pond removes pollutants and sterilizes the outflow.
