Fremont FAQ
Can I use rainwater for my vegetable garden?
Yes. California permits rainwater from rooftops for irrigation of edible gardens. Avoid watering leafy greens directly from an uncovered barrel, and let the water soak into the soil rather than spraying directly on produce.
Do I need to do anything for mosquitoes?
Yes. All barrels and cisterns must be covered with 1/16 inch or finer screen to prevent mosquito breeding. Alameda County Mosquito Abatement can inspect and require corrections under state public health law.
