The Municipal Drainage Utility

The Municipal Drainage Utility is the City of Irving's stormwater utility. This division is funded out of a drainage utility fee collected from residents and businesses on the respective water bills. This enterprise funded utility is responsible for reducing flood risk for the city, improving the function and health of stormwater infrastructure, and protecting the surface water quality of the city's creeks, streams, and waterways.

The MDU is divided into 3 subdivisions, each with their respective areas of responsibility. The operations and maintenance division is responsible for all things stormwater infrastructure. From de-silting ponds to underground pipe repairs, this group keeps the structural system performing at the designed efficiency in order to reduce flood risk. This group maintains the 4 waterway trash and debris collection structures that provide support to litter control efforts, as well as the corridor litter control program designed to remove trash and litter before it enters the city's waterways.


The engineering team is responsible for planning, designing, and managing construction efforts of new infrastructure. The Drainage Solutions for a Better Tomorrow provides bond funding for capacity improvements to the major conveyance channels in the city, and part of this funding is dedicated to neighborhood drainage projects to provide relief for smaller scale flood prone areas. The primary goal of these projects is to remove homes from the 1% annual chance event (100-year flood) which reduces flood risk in the city. More information about MDU Engineering can be found in the Engineering Services tab.


The compliance group is tasked with keeping the city of Irving in compliance with state and federal storm and surface water quality regulations. There are regulatory guidance documents, best management practices, and envirnomental principles that the city must follow in order to protect creeks, streams, and waterways in Irving from pollution.
