The Ramona Municipal Water District has compiled a Board-approved list which contains the names of backflow prevention assembly testers doing business in San Diego County who have been certified by the American Water Works Association (AWWA), the American Backflow Prevention Association (ABPA) and/or the American Society of Sanitary Engineering (ASSE). The District has verified these certifications but makes no other representation concerning the qualifications of these testers. The listing is not intended as either an advertisement for these testers nor as a warranty by the District, express or implied.
