In South Dakota, water reuse for water reuse for landscapingThe use of recycled water on land to assist in the irrigation of vegetation in residential and non-residential areas. Includes impoundments to store water for irrigation , ornamental vegetation, parks, school yards, sporting facilities (including golf courses), private gardens, roadsides and greenbelts, and cemeteries. Excludes irrigation of areas used for agriculture, commercial reuse applications, or any centralized non-potable reuse. includes golf courses, parks, playgrounds, lawns and other areas with public access. The source of water treated municipal wastewater Treated wastewater effluent discharged from a centralized wastewater treatment plant of any size. Other terms referring to this source of water include domestic wastewater, treated wastewater effluent, reclaimed water, and treated sewage. is specified by the state as treated municipal wastewater effluent. This write-up uses state terms when discussing sources or uses of water that may differ from the Regulations and End-Use Specifications Explorer's (REUSExplorer's) terms.
Technical basis
South Dakota provides guidance on the use of wastewater for irrigation equipment at golf courses, parks, playgrounds, lawns and other areas with public access (South Dakota DENR, 1991). All applicable provisions of the Clean Water Act (CWA) (33 U.S.C. §§ 1251 et seq.), including its implementing regulations, must be met in addition to any relevant rule requirements under the Food Safety Modernization Act (FSMA) (124 Stat. 3885). Treatment requirements and performance standards are applied for the removal of microbial contaminants and chemicals for water reuse for landscaping and are summarized in the table. The technical basis for developing the specifications and/or removals of microbial contaminants and chemicals is not explicitly specified.
Water reuse for landscaping approved for use in South Dakota
South Dakota DENR (1991) defines the following approved water reuse for landscaping for the irrigation of:
- Golf courses
- Parks
- Playgrounds
- Lawns
- Other areas with public access
Water reuse treatment category for landscaping
South Dakota does not assign classes or categories to treated wastewater effluent in regards to water reuse for landscaping. However, secondary treatment followed by disinfection is required when municipal wastewater effluent is used for the irrigation of golf courses, parks, playgrounds, laws and in other areas where the public has access. South Dakota specifies that disinfection must be “sufficient to ensure that a geometric mean number of total coliform organisms does not exceed 200 organisms per 100 milliliters which should be adequate to protect human health. It should be realized, however, that this level probably will not eliminate all pathogenic viruses” (South Dakota DENR, 1991). At least one representative sample of the wastewater should be collected and submitted to the Water Quality Laboratory, Brookings, South Dakota, for analysis and a preliminary interpretation of irrigability. If the effluent, after treatment, cannot meet the requirements of ARSD 74:03:15 of the Groundwater Quality Standards, a Groundwater Discharge Plan may be required. In South Dakota, disposal of contaminated water is not considered to be irrigation unless other water is used along with the contaminated water.
Additional context and definitions
Requirements for signage and the use of purple pipes for the conveyance of reclaimed water for reuse applications are not specified.
