Grey water systems need to be installed keeping these few practices in mind:
- The grey water should not get in contact with any roots of vegetable plantation or food.
- If grey water is not contained within the site where it is generated, it will be considered a nuisance and will be subjected to Code Enforcement action pursuant to City Code Section 1-3 “Administrative Review of Ordinance Violations.”
- Even though grey water is defined as all waste water except toilet water from the household, there are still some limitations as to what can enter the grey water system. Some of these are water wasted from cleaning car parts, washing diapers, and greasy oily rags. This is because of the dangerous chemicals in them.
- The waste water mentioned above should be diverted to the septic system. It should not be used for irrigation.
- The grey water system can only direct the water to a landscape area which should be appropriate for its use.
- Electrical and/or structural components of a building should not be affected by the grey water system.
- There should be no spray irrigation connected to the grey water system.
- Grey water is not allowed to be stored anywhere (storage tank or tub). For it to be stored, the code requires filtration and a permit.
- The grey water system should be designed in such a way that it prevents any contact with humans and animals.
- There should be no potable water connection or a pump with the system. The pump in a washing machine is not a part of the grey water system.
- Grey water is not to be used for lawn irrigation. It is to be directed to irrigation basins only, which are 1 ft wide and 1 ft deep. Grey water can also be used to irrigate raised beds.
- The grey water system should be designed in such a way that it allows the user to direct the flow of water for irrigation, disposal, or the sewer. The direction control in the Laundry to Landscape (L2L) Schematic is called the “Three-Way Valve”.
- To further prevent humans and animals from coming in direct contact with the grey water, there is at least 2 inches of appropriate permeable cover (rock, soil, mulch etc) where grey water is used or released.
