Other Service Gill Septic Provides

Connecting Your Delaware Septic to your city sewer line system. Changing from a septic system to sewer involves guidelines from the State of Delaware.

(Delaware offers 2,509 - Total stream and river miles.) Changes do need to be made and steps are being taken! The easy fixes to the state's water problems are in place, including removing pipes that once spewed minimally treated sewage and manufacturing process water into rivers and streams. And getting rid of septic systems that fail. Either by installing a new one correctly or by offering means to connect to city lines.
