<br />Rainwater Harvesting Policy <br /> <br />benefits that residential harvesting will not achieve. The Code Guide discourages some types <br />by requiring case by case permits that are generally too complicated to be carned out by <br />anyone other than professional rainwater harvesting experts, of which there are simply too <br />few. The cost also is needlessly escalated. <br />· Allow all potable & nonpotable uses (with appropriate filtration/purification). "Harvested <br />rainwater may only be used for water closets, urinals, hose bibs and irrigation purposes" <br />(Code Guide, p. 3). Rainwater has been & is safely used the world over for every water use. <br />Restricting the use of rainwater to specific tasks is unnecessary. <br />· Allow a variety of cistern sizes. Requiring a 1,500 gallon cistern or height/width ratio (p.7) <br />is excessive. It is not necessary to dictate storage site, shape, type or pipe type. <br />· Implement the folloWing rather than adopting the Code Guide. Adopt the following <br />guidelines, Design & Maintenance of Rainwater Harvesting Systems. If you wish to <br />encourage rainwater use, it must be easy to follow your rules. <br />· Bottom line is - Only three rules are necessary for potable systems: 1) Filtration & <br />purification must meet local, state & federal drinking water quality standards, 2) Periodic <br />water quality testing is needed & 3) avoid cross contamination or backflow. <br />· No rules are necessary for nonpotable outdoor systems. . <br /> <br />Tammie Stark, M.A. @ <br /> <br />Page 4 of 8 <br /> <br />5/3/2006 11:53:57 AM <br />
