Program Area

The Septic System Rebate Program area is within the boundaries of the San Diego portion of the Rainbow Creek watershed. Rainbow Creek collects water from nearly 6.7 square miles and empties into the Santa Margarita River. Rainbow Creek begins east of Rainbow Valley, in the surrounding hills, and flows west, under the Interstate 15 Freeway, through the northern region of Fallbrook to the river. If you are unsure if your property is located within the Rainbow Creek Watershed, please contact Bethany Principe at (760) 728-1332 or beth@missionrcd.org.
