8. www.solarterra.com, Copyright 2010, Rainwater Catchment Systems How much water? –Irrigation –Potable –All water (off-grid) What types for NAZ? –Clean air = clean water –Freeze protection required What Technology? –Fully buried: fiberglass and metal –Above ground or partially buried: poly and metal Understand yours or your client's lifestyle requirements and personal goals for solar thermal Where about equipment? –Simple roof design is best –Gutters must be STRONG, downspouts min 3 inches –All fill pipes must slope ¼” per foot –Storage tank(s): near home or remote –Pumps, filtration and purification –Back-up water – city or hauled –Plumbing with constant water must be freeze protected, large tanks do not Other considerations –Maintenance –Snow
