Before sunrise on an August morning in Leander, the only sounds are cicadas winding up and sprinklers hissing across dark lawns, in the cool hour when water soaks in instead of rising off as steam. Eco Irrigation and Landscaping sets up systems for that hour, placing each run of pipe and each spray head so every corner of a yard gets its share and the sidewalk stays dry. The soil here is a thin skin over rock, and a summer of triple-digit afternoons tests every system in town. Alongside the irrigation comes landscape work that fits the water: beds grouped by thirst, bare ground covered against the sun, plantings that settle in rather than wilt. By the time heat shimmers off the pavement, the yard has already had its drink.
