| Eastside Water Treatment Plant Expansion Program |

This project entails construction of clear-wells, deep concrete flumes, and junction structures. Construction phasing and coordination with the plant operations is critical due to the existing undersized clear-wells that must remain in operation while constructing around them and then demolition of these facilities and for construction of the remaining clear-wells and deepest flumes. The concrete flumes range in size from 10'X10' to 12'X12' inside dimensions and are to be constructed at up to 45 feet total depth. The junction structures are equipped with slide gates for flow control and are to be constructed of 48'-6" walls. The clear-wells are to be constructed of wire-wound pre-stressed concrete. These 15.625 million gallon storage tanks will be the largest tanks constructed by this method in the world. This improvement consists of 15,000 yards of concrete with 120,000 LF pipe ranging in diameter from 3/4" to 84". This project has a 3 year construction schedule. Additional improvements include new rapid mix basins, chemical buildings and feed systems and new electrical work. Demolition and relocation of existing facilities and buildings is also required of this improvement project in addition, this project also has upgrades to filtration and distribution pump stations will be the largest expansion for Dallas Water Utilities to date. Following the completion of this group of projects, the East Side Water Treatment Plant will be rated at 540.
