Pittsburg, CA Landscaping Rules: Water Restrictions (2026)

Water use in Pittsburg is regulated by permanent statewide conservation rules adopted by the State Water Resources Control Board, overlaid with Contra Costa Water District (CCWD) and the City of Pittsburg Water Division restrictions as conditions change. Permanent prohibitions under the State Water Board's conservation regulation include: no application of potable water to outdoor landscapes in a way that causes runoff onto sidewalks, driveways, streets, or gutters; no watering within 48 hours after measurable rainfall; no hosing down of driveways, patios, and other hardscapes except for health and safety reasons; no operating ornamental fountains unless they recirculate water; no watering turf on public street medians; no washing vehicles with a hose lacking a positive shut-off nozzle; and no serving water in restaurants except on request. Under AB 1668 and SB 606 (Making Conservation a Way of Life), urban water suppliers must meet indoor residential use standards (42 gallons per capita per day by 2030) and outdoor budgets tied to MWELO. During drought emergencies, CCWD can activate stages with assigned-day watering schedules (for example, even-numbered addresses on even days), reduced watering duration, and surcharges on excessive use. New landscaping over 500 square feet must comply with MWELO water-budget standards.
