Water Distribution Systems

The Monterey Peninsula Water Management District (MPWMD or District) has enacted Rules & Regulations based on a series of ordinances. These include the regulation of Water Distribution Systems. These 2014 Implementation Guidelines are associated with Ordinance No. 160 (adopted April 21, 2014 and effective May 21, 2014), which makes comprehensive changes primarily to MPWMD Rules 11, 20, 21, 22 and 173. The intent of these Guidelines is to provide a “road map” for the public and District staff on how various types of water systems are now regulated. The following links provide information needed to apply for permitting and review.
