The project goes beyond creation of a model home and landscape. As state and local codes currently prohibit treated rainwater use in the home, realization of the project required reforming regulatory constraints that limit green development. The process included revision to Norris' ordinances to allow treated rainwater use and started a new regulatory conversation concerning state issued permitting for residential greywater treatment. The project team worked with the Tennessee Department of Environment and Conservation (TDEC) for two years to obtain experimental permits for the greywater system that would ensure safe operations and responsible monitoring and data collection. Experimental permits were to remain in place for only the duration of the study. As of this entry, the project team, TDEC, the City of Norris, and the Norris Water Commission are working together on deed restriction language that will allow the designed greywater system to remain in place in perpetuity, and to transfer the operation permits with ownership transfers. The ordinance allowing rainwater treatment and use systems at the NNH will also be made permanent in City of Norris' code. The New Norris House and landscape case study and research findings are catalyzing development of and advocacy for policy revisions in Tennessee by TDEC.
