American Cities are faced with aging infrastructure such as bridges, streets, power transmission lines, and the stormwater systems. Large projects of this type take time to plan and implement. Stormwater infrastructure is not often as top-of-mind as other projects, but it is vital to the flood protection system in any city. These city-wide systems convey stormwater away from residential and business districts during heavy rains. Typically, the components include pump stations, flood warning gates, sump systems, and levees. Over the years through bond programs, Dallas positioned itself to meet the challenge of upgrading the storm water system under the Flood Protection component of the Trinity River Corridor Project. As the ninth largest city in the U.S., Dallas is always working ahead. Currently, one major pump station is underway, Able Pump Station, and it is scheduled for completion in 2017.

The 2006 Bond Program, Proposition 2 provided funding for the design and construction of Flood Protection and Storm Drainage Facility projects. Currently, Dallas has six pump stations in the downtown Dallas area: Able (two existing and one under construction), Baker (two existing stations and one new construction complete in 2016), Charlie, Delta, Hampton, and Pavaho

The function of these stations is to pump the water that fills into the sumps on the dry side of the Dallas Levee System from storm drains and rain water and convey the water into the Dallas Floodway. A seventh pump station is planned in the future, and it will be built near the West Levee past Hampton Road close to the downtown area.
There is an additional pump station that serves the Rochester Levee located by William Blair Park at 3000 Municiple Street, Dallas, TX 75215 in the Great Trinity Forest.

Able Pump Station
- Able Pump Station is two stations serving the Central Business District Community. Small Able was originally built in 1932 and Large Able was built in 1954. The current capacity of the pump stations is 220,000 Gallons Per Minute (GPM). The new Able Pump Station is under construction along Riverfront Blvd. not far from Fuel City. The station will feature concrete volute pumps, the same as are installed in Pavaho Pump Station and Baker No. 3. The station's pumping capacity will exceed 800,000 GPM when it is complete in 2017.

Baker Pump Station
Baker Pump Station consists of Old Baker built in 1932 and New Baker built in 1975, it serves the Design District and Stemmons Corridor with current capacity of 600,000 GPM. The new pump station is accommodating approximately 700,000 GPM, bringing the total pumping capacity of the Baker Station to 1,100,000 GPM for the neighborhoods and business districts east of the Dallas Floodway. Baker No.3 cost is $48.1 million. The station features four
high efficiency corrosion-resistant Concrete Volute pumps and the latest in pump station computerization and technology.
Baker No. 3 Pump Station
Charlie Pump Station
- Charlie Pump Station built in early 1932 serves the area around the Bottom Community with a pumping capacity of 80,000 Gallons Per Minute (GPM). The new capacity for this station will accommodate approximately 225,000 GPM.
Delta Pump Station
- Delta Pump Station built in early 1932 serves the West Dallas Community near Hampton Avenue Bridge with a pumping capacity of 80,000 Gallons Per Minute (GPM).
Hampton Pump Station
- Hampton Pump Station is two stations with Old Hampton built in 1955 and New Hampton built in 1975. It serves the North West Dallas Community with a current capacity of 600,000 Gallons Per Minute (GPM). The new pump station will accommodate approximately 700,000 GPM and in this case, the combined pumping capacity will equate to 1,100,000 GPM.
Pavaho Pump Station
Pavaho Pump Station at Canada Drive
Pavaho Pump Station which supports the storm drains along Canada Drive in West Dallas was constructed in the 1950s. The original Pavaho Pump Station pumps at a capacity of 80,000 gallons of water per minute as the sumps fill with stormwater during rain events and this station remains fully functional. The new, high capacity $27 million Pavaho Pump Station pumps at 375,000 gallons of water per minute.
The pumping station alongside the original structure provides outstanding reliability and lower maintenance which positively impacts the efficiency and cost of operating the station. Three high efficiency corrosion-resistant Concrete Volute pumps generate an increase in power for the new station. These three pumps were the first of their type in use in America. Concrete Volute Pumps provide quiet delivery and important elevated pumping capacity for neighborhoods and business districts in West Dallas. The funding for this project was approved in the 2006 Bond Program. City engineers worked with Jacobs Consultants and the station was built by BAR Constructors, Inc. The pumps are from Flowserve.

Rochester Pump Station
Rochester Pump Station built in 1992 servers the Rochester Levee and the Central Wastewater Treatment Plant. It has a pumping capacity of 85,000 Gallons Per Minute (GPM).
