When a project calls for a rainwater collection system, as the one above did, Specht Harpman turns to Tank Town. The Texas-based company bills itself as a one-stop shop for all things water catchment-related, including various types of fiberglass and metal tanks, filters, pumps, and ultraviolet lights. System offerings are sized from 5,000 gallons to 50,000 gallons. Tank Town, 512.894.0861; www.rainwatercollection.com.
