Beginning June 1, 2010, all new one- and two-family dwellings are required to have gray water stub-outs for laundry drains. In addition, new single-family dwellings will be required to have separated drain lines for lavatories, showers, and bathtubs to allow for future installation of distributed gray water systems.
