Official summary
Abstract published by the legislature (via Open States). Text as published by the legislature; reproduced verbatim.
This Act prohibits counties and municipalities from requiring the use of water backflow preventers in certain types of low hazard buildings. In doing so, this Act reduces costs for businesses and single-family residential homeowners by exempting them from backflow preventer installation and inspection requirements in buildings where backflow does not pose a risk to fresh water or drinking water. Buildings deemed low hazard will nonetheless be required to have backflow preventers if they have fresh water supplied by a public well. Under § 1 of Article IX of the Delaware Constitution, this Act requires a two-thirds majority vote because it involves indirect changes to municipal charters.
