Fixed sensors for catch basin inspection?
Would a miniature sensor mounted to catch basin grates and networked via cell and/or satellite be considered or is the solution required to use a vehicle mounted sensing system?

No, a project to deploy fixed sensors for catch basin inspection will not be considered. The large number of catch basins owned and maintained by State DOTS and municipalities make the solution too costly for practical application. Knowledge of the performance of water-quality sensors in these environments would suggest that there would be a frequent need to clean and recalibrate fixed sensors, which would put highway workers in harms way. Stationary transmitting sensors would need battery replacement, which would put highway workers in harms way. The liability for emplacement of equipment in the right-of-way (such as solar panels to power the sensors or antenna to transmit data) is large. The catch basin environment is difficult on electronic equipment with freezing, flooding, and sediment and debris flow being common occurrences.
