Where does the water go? After a hard North Texas downpour, every Colleyville yard faces that question, and the dense clay beneath the turf is slow to help. Streamline Designs Sprinkler and Drainage shapes its work around both halves of the problem its name describes: sprinkler coverage for the dry stretches of July, drainage for the nights when the rain arrives all at once. A lawn here can swing from puddled to parched inside a month, and the art is giving it neither too much nor too little. Runoff that leaves the yard where it should, coverage that soaks evenly from foundation to curb, turf that stays firm underfoot: the result is plain on a bright morning after a storm. Good water work hides itself, and you only notice that the yard never seems troubled by the weather.
