A remarkably simple code, for residences applying less than 250 gallons per day of graywater.
- Aeration of graywater is not allowed.
- Unlike some states mentioned later in this chapter, rather than specifying soil loading figures, New Mexico simply states „to ensure that the hydraulic capacity of the soil is not exceeded‟
- Produce irrigation is not prohibited.
No permit is required.
