A common question that is always asked by builders and rainwater system owners alike is "do you have to have any type of specialty permiting for installation?"
The answer I'm afraid, is not a simple one, it varies with each municipality, whether you are within county limits or in city limits. Another barrier to entry is that rainwater collection and the technology used in harvesting it is very "fresh", and governing bodies are unfamiliar with the renewable energy industry as whole. Granted, geo-thermal & solar resources have been around for the better part of 2 decades however, regulations & permitting for these energy sources change on a yearly basis on both the federal & state levels. Rainwater collection is new to almost all areas of our country within the past 8 years. Two states that have really championed the regulations & guidelines for the installation of these systems, is Arizona and California. In fact, many of the recently adopted codes in North Carolina and surrounding states have been benchmarked off of these code setters within these states.
Buncombe County & Haywood County have recently made some substantial head way in regards to promoting such a powerful renewable energy source such as rainwater. With each system that our company installs whether it be above ground or below ground, we obtain the proper plumbing permit's and follow each municipalities guidelines for rainwater system installation. It is part of our company’s policy to inform and educate the public & private sectors on all of the benefits that not only the owner will receive but also the governing body. Each system must have a first flush diverter, non-potable piping must be labeled, signage attached, and there must be an overflow for each cistern. Within the international plumbing code, there have been some appendices added for rainwater recycling, for the most part many of these codes fall in line with a greywater water recycle system.
If you have any questions or have some concerns in regards to a greywater or rainwater system, please feel free to contact me!
