Storm Sewer Assessment Program

In 2015, as part of a larger initiative to improve the City’s asset management program, Tulsa called on Meshek to perform a single-basin inventory and assessment of Storm Sewer assets as a pilot project.

This kicked off a 10-year phased program to inventory and assess the Storm Sewer system of the entire City. The program was phased by drainage basin, beginning in the oldest parts of the City where risks of failure in infrastructure from age were deemed most likely. The original 10-year cycle is now nearly complete.

For several of these basins, Meshek simultaneously deployed as many as three field teams to conduct surface inspections and confined space subsurface inspections.

To collect, inventory, and assess the conditions of the infrastructure, field technicians use tablets and sub-meter GPS receivers. The technicians use feature services -- enabled for disconnected editing -- for data collection in the field. Edits are synced daily.

In addition to our own staff, we also coordinate and review the collection of other contractors who engage in traditional unmanned CCTV-crawler-based inspections of the pipes. Their data and our data are combined -- including all photos, videos, and reports -- and the updated data is provided to the City to integrate into the master layers of the City’s Storm Sewer system.
