Stormwater Management: Rialto vs San Bernardino

Do I need a permit to wash my driveway in Rialto?

Wash water cannot discharge to the storm drain. Use dry methods (sweeping) or capture and dispose of wash water to the sanitary sewer with permission. Untreated discharge of soap, oil, or sediment to the gutter is an illicit discharge under Title 13.

When do I need a SWPPP for construction?

Any project disturbing 1 acre or more (including smaller sites that are part of a larger common plan) must obtain coverage under the State Construction General Permit and maintain a SWPPP. Smaller sites in Rialto still need erosion and sediment BMPs under the city WQMP.

Can I drain my pool to the street?

Only if dechlorinated and pH-neutral, and only with prior approval. Generally Rialto requires pool water to be discharged to the sanitary sewer via an approved cleanout.

Can I wash my car in my San Bernardino driveway?

Residential car washing is generally exempt if runoff does not carry soap or sediment to the storm drain. Use biodegradable cleaners, wash on grass or gravel where water absorbs into the soil, or take the vehicle to a commercial car wash that captures wastewater.

How do I drain my swimming pool without violating stormwater rules?

Dechlorinate pool water for at least 48 hours before discharging, confirm no visible color or odor, and drain slowly to your sewer cleanout where allowed or to landscaped areas that absorb water. Never drain directly to a street or storm drain.
