500 S. 4th Ave, Brighton CO 80601 – ph: [PHONE REDACTED] May 17, 2013 Dear Utility Customer, The City of Brighton Utilities Department is committed to provide cost-effective wastewater service to commercial and residential customers. We are equally dedicated to operating our wastewater system in an environmentally responsible manner. Consequently, in 2011, the City of Brighton Council approved the revision of Section 13-12-210 of the Municipal Code pertaining to sand-oil separators. In order to uphold the above Ordinance, the City has developed a Sand- Oil Separator Control Program, which includes inspections performed by trained city personnel. Unannounced semiannual inspections will start by June 2013. To assist your understanding of this program, an educational packet is enclosed with additional information. Sand-oil separators are pretreatment devices commonly used in vehicle related facilities as a method to separate sand and oil from wastewater discharges. They are typically installed in a maintenance shop area and receive oily wastewater generated during processes such as vehicle maintenance and washing. The effluent from sand-oil separators is discharged to the public sanitary sewer system. Discharges of commercial and industrial wastewater are regulated under the Clean Water Act (CWA). Properly designed, installed and operated sand-oil separators provide a treatment system for handling oily wastewater that prevents the entry of unacceptable levels of contamination to the public sanitary sewer system. However, sand-oil separators are generally not designed to separate high concentrations of oil, such as might occur, for example, when a large quantity of oil or sludge is spilled or poured into a wash bay drain. It is important for all personnel who discharge wastewater into a sand-oil separator to understand how they function, including their limitations, in order to prevent them from becoming sources of environmental pollution. The City of Brighton is obligated to keep the City infrastructure in excellent working condition. It is the Utilities Department’s mission to eliminate the amount of sand and oil that is deposited in the public sanitary sewer collection system. For additional information regarding the sand-oil separator control program please feel free to contact us. Sincerely, Juliana Archuleta Utilities Department [PHONE REDACTED] Enclosure
