What it is and who needs it.
What the bond actually guarantees
The Metropolitan St. Louis Sewer District (MSD) licenses the plumbers, sewer, and drainlayer contractors who connect to and work on its public sewer system, and conditions that license on a $10,000 surety bond. The bond stands behind your compliance with MSD's rules and the work you perform on the District's system.
It's a three-party arrangement: you (the principal), the surety carrier, and the Metropolitan St. Louis Sewer District (the obligee). The bond guarantees that your sewer and drainlaying work meets District standards and that damage to the public system is made good. If you fail to, MSD can recover against the bond.
It is not insurance for you — if the surety pays an MSD claim, you repay the surety. Contractors who build to District standard treat the bond as a license formality.
