Tarpon Springs was built on sponges hauled from the Gulf, and along Dodecanese Boulevard they still hang in bundles at the docks, drying beside the boats that work the Anclote River. A town that knows just how much water a sponge can hold understands the value of getting water where it needs to go. In winter, manatees drift into the spring-fed water of Spring Bayou, where Victorian homes sit back among palms and green lawns. ATZ Irrigation, Inc brings irrigation work to Tarpon Springs, setting sprinklers and lines so each zone soaks the soil it was meant for and leaves the walkway dry. In coastal soil that drains as fast as it is watered, a well-run system keeps a yard as green as the bayou in January.
