August in Purvis can go three weeks without rain, and the sandy loam here gives up its moisture in a hurry. Greenview Irrigation answers that with water put exactly where it belongs: sprinkler systems installed and tuned, heads adjusted and repaired, zones timed to run in the blue hour before sunrise when nothing burns off. Stand in a yard at that hour and the arcs of spray catch the first light while the rest of the street is still asleep. Lawns from Purvis out to Sumrall and Oak Grove hold their color through the hardest weeks of the summer. Mowing and upkeep finish the picture, but it is the water that makes the picture possible at all.
