A. Graywater systems may be installed; provided, that the owner of the property where the system is to be located obtains a permit from the City pursuant to this section. “Graywater systems” shall be defined to mean a plumbing system for a single-household dwelling where untreated wastewater which has not come into contact with toilet water or human waste is disposed of on site, and not via connection to the City wastewater treatment system. Graywater includes water from bathtubs, showers, clothes washing machines, and sinks, but does not include: water from kitchen sinks, dishwashers, floor drains, or drains receiving chemicals or industrial wastes.

B. Graywater systems shall not be connected to culinary water systems, except where a backflow prevention device is installed and maintained in working order at all times.

C. Notice of the installation of an approved graywater system must be confirmed in writing, signed by the owner and recorded in the Grand County land records as to the subject property.

D. Graywater shall not be: (1) applied to the land surface; (2) allowed to surface after disposal; (3) applied directly to vegetable gardens; or (4) discharged directly into any ditch, canal, storm sewer, or surface water body. The City has authority to issue a permit variance as to requirements (1) or (3) if the applicant can successfully demonstrate the use of technology which will remove contaminants and render the water safe for those activities. All graywater piping and equipment shall be clearly labelled to show that the water is nonpotable and not safe for drinking.

E. All graywater systems are subject to the design requirements and restrictions contained in U.A.C. R317-401. The City shall review and process all graywater system applications, and may establish a fee for graywater permits by resolution.

F. The City has authority to enter private property and periodically inspect for the purposes of verifying compliance with this section. Inspections may include effluent sampling, physical inspections, and/or records reviews, as needed.

G. The use of any unpermitted graywater system or any graywater system which does not comply with the provisions of this section shall be unlawful. (Ord. 19-13 § 21 (part), 2019; Ord. 17-30 (part), 2017)
