# Duluth UDC § 915.03

Sanitary Sewer Disposal

**Governing jurisdiction: Duluth.** A "Duluth, GA" mailing address is usually NOT in the City of Duluth. Unincorporated Gwinnett is 67.3% of the county's land area and is governed by a different code, a different board and a different permit portal. Resolve the governing jurisdiction before answering any zoning question.

## Text

1. Connection to an approved sewage disposal system shall be made, which may require the construction of
an on-site system or the extension of public sanitary sewerage and associated appurtenances, as required
under the Department of Water Resources Regulations of Gwinnett County or as required by the
Gwinnett County Health Department.
2. No septic tanks or other individual on-site sewage disposal system shall be allowed if public sewer is
available. All structures shall connect to public sewer, when such sewer is available, in accordance with
the Sewer Regulations of Gwinnett County. Sewer availability shall be determined by the Gwinnett County
Department of Water Resources.
3. Communal on-site sewage disposals are prohibited. Privately financed wastewater disposal plants, septic
tanks, or other sewage treatment system, serving more than one residence or more than one property,
are prohibited. If a property does not use an individual on-site sewage disposal system, it must be
connected to a sewer leading to the publicly owned treatment works.
4. Lots with septic tanks and tile drain-field sewerage disposal systems shall contain the contiguous area
outside of the 100-year floodplain as required by the Gwinnett County Health Department.
5. The Gwinnett County Health Department may require notation that certain lots must meet additional
requirements prior to issuance of a building permit or otherwise limit development relative to Health
Department regulations.

a. Such lots may include lots upon which adequate depth to water table must be demonstrated

during the appropriate season of the year, adequate percolation tests must be performed,
limitations upon the number of bedrooms in a dwelling, etc.
b. No lot shall be included on a Final Plat which the Health Department is not confident will meet all

Health Department regulations at a reasonable cost or within a reasonable period of time, except
lots proposed to be served by sanitary sewer in subdivision where "dry" sewer has been
installed. Such lots shall be noted - "Approval by Department of Water Resources for connection
to sanitary sewer required prior to issuance of a building permit."
