Spring Valley, Calif. – The Otay Water District has launched its annual WaterSmart Landscape Contest. Given that more than half of residential water use occurs on landscape irrigation, the contest aims to encourage outdoor conservation during the drought. The District awards the title “Best in District” and a nursery gift card, among other prizes, to one resident for their attractive, drought-tolerant garden. The deadline to enter is Friday, May 12, 2023.
