Senoia, GA Sewer and Drain Service: Local Rules

Georgia Sewer clears, inspects and repairs the private side of sewer and water lines for homes served by the City of Senoia's sewer system. Past the city tap, the lateral and the trunk line are the city's, and a suspected problem there goes to City Hall or, after hours, the police department; from your house to the tap is the owner's building sewer, and that is the part we work on, so call us at (404) 482-2527.

The City of Senoia runs its own water and sewer system, and its code includes a rule that reaches into new kitchens: new residential developments may not include garbage disposals (Sec. 70-101). The code is equally direct about where the owner's pipe ends.

The city-page details below come from archived copies of Senoia's website made in 2024 and 2025, and the rules come from the city code on Municode. City Hall can confirm current contacts.

The City of Senoia's Public Works Department manages the city's wastewater system (City of Senoia), and city crews also maintain the water lines, flushing them when residents report discolored water (Public Notice). The city's sewer use rules apply to its residents and to all users of the city's water and wastewater systems, including people outside the city who use them by agreement, and a director of the water and wastewater department enforces them (Sec. 70-76).

If your home is outside the city limits and not on the city system, the Coweta County Water and Sewerage Authority is the county's public sewer utility.

The city's Building Department issues permits, checks plans and inspects work for code compliance, including electrical, plumbing and mechanical permits, single-family homes and residential remodels; City Hall staff help with fees, requirements and inspection questions and keep permit records by address.

If your job needs a permit, we tell you before work starts. Before connecting, the code requires buildings that can reach public water and sewer to be connected before a certificate of occupancy is issued (Sec. 70-80). Before a trench is opened, Georgia 811 asks for a locate request at least three business days ahead (Georgia 811); the law requires one whenever machines do the digging (dig law).

Senoia's grease ordinance targets fats, oils, grease, grit and other solids that can block the sewer and cause overflows. Most of it governs restaurants, which must install permitted grease interceptors and clean them on schedule, but one clause applies to homes: to reduce the organic load entering the sewer and keep the plant's discharge within state guidelines, new residential developments may not include garbage disposals (Sec. 70-101).

Rainwater is kept out as well. No user may send stormwater, surface water, groundwater, roof runoff, subsurface drainage, swimming pool drainage or condensate into the city system unless the director specifically authorizes it (Sec. 70-91). For wipes, paper towels and other bathroom items, see what not to flush or pour.

Where a building cannot be served by public sewer, the city issues no construction permit or certificate of occupancy until the Coweta County Board of Health has issued a septic permit (Sec. 70-80). If public sewer later becomes accessible and an existing septic system fails, the system may not be repaired; the owner must connect and remove or fill the old tank (Sec. 70-82). The Coweta County environmental health office, which the Department of Public Health lists at 28 East Washington Street in Newnan, keeps septic permits and records (DPH).

If you are building in Senoia, tell your designer and plumber about the garbage disposal ban for new residential developments before the kitchen is planned. For an existing home, we clear the building sewer with drain cleaning or main sewer line cleaning, use a sewer camera inspection to find where the problem sits relative to the city tap, and handle sewer line repair on the owner's side. When a failed septic system means the house must connect to public sewer, we can run the sewer line replacement from the house to the tap; removing or filling the old tank is a septic contractor's job. Call Georgia Sewer at (404) 482-2527.
