Detention basins and subdivision storm systems

Many subdivisions and commercial areas drain to detention basins through inlets, pipes and outlet structures. Those systems are often owned by an association or a business rather than by the public, and they need maintenance: outlets clog, structures fill with sediment, pipes separate and inlets settle.

Storm work on such a system tends to follow a sequence:

• Clean the inlets, pipes and outlet structure with a vacuum truck to restore flow and allow inspection.
• Inspect the structures and, where possible, the pipes, to find cracks, separations or collapses.
• Expose and replace damaged sections, keeping the pipe at its design grade, with hydro excavation used near other utilities.
• Rebuild settled inlets and restore the surrounding pavement or turf.

We will ask who owns the system, what its owner requires and whether the public owner has sent any notice about its condition.

We handle water services, sewer laterals and conduit in O'Fallon as well.
