Antioch FAQ
What days can I water my lawn in Antioch?
During non-drought periods there is no assigned schedule, but you must avoid runoff, hardscape hosing, and daytime watering. Drought stages may activate odd/even schedules - check antiochca.gov/water.
Does MWELO apply to my home landscape remodel?
MWELO applies to new and renovated landscapes over 500 sq ft that require a permit. Smaller residential projects are exempt, but all water-waste prohibitions still apply.
Pittsburg FAQ
Can I water my lawn every day?
Generally no. CCWD typically limits watering to assigned days during drought stages, and statewide rules prohibit watering within 48 hours of rain or producing runoff onto hard surfaces.
Can I wash my car in the driveway?
Only with a hose that has a positive shut-off nozzle, and without creating runoff onto the sidewalk or street. Using a commercial car wash that recycles water is more drought-friendly.
What is MWELO?
The Model Water Efficient Landscape Ordinance sets water budgets for new or rehabilitated landscaping over 500 sq ft, requiring efficient irrigation, drought-tolerant plants, and mulch.
