Much of St. Louis's sewer infrastructure dates to the early 1900s and consists of vitrified clay pipe. These lines have limited capacity and are prone to root intrusion and structural failure. When your grease interceptor allows even small amounts of FOG to pass through, it combines with the reduced flow capacity in aging laterals. The result is blockages that back up into your building. Modern grease trap pumping schedules must account for this infrastructure reality. A trap that would perform adequately in a newer suburb requires more frequent service in neighborhoods with century-old sewer connections.
The Metropolitan St. Louis Sewer District has intensified FOG enforcement in response to chronic sewer overflows. Restaurants in high-density areas like Downtown, the Central West End, and Delmar Loop face regular inspections and mandatory pumping documentation. Choosing a local provider familiar with MSD reporting requirements protects you from compliance failures. We know which forms to complete, how to document service frequency, and what records to maintain. This local knowledge prevents fines and keeps your operating permits current.
