This project entails process-related upgrades to the bryant street pumping station potable water spillage header system including replacement of seven 16-inch manual pressure control valves with new automated pressure control valves, replacement of fourteen 16-inch isolation valves and ten 16 to 24-inch interconnecting valves with motor operated butterfly valves, installation of nine new 24 to 36-inch magnetic flow meters, installation of new air release valves, installation of associated electrical and instrumentation systems, structural improvements to pipe supports and safety hand rails, and other upgrades to the spillage header system integration with supervisory control and data acquisition - scada.

Interior alteration to install access control to existing doors to increase security for existing bryant street pump station.

Dc water is requesting an after hours permit to acquire ground penetrating radar (gpr) data on the b st nj ave trunk sewer which runs along roadway or sidewalk, within thw public right-of-way, or a dc wasa easement on private property in the northeast and southwest quandrants of dc. The roads associated with this pipe have a high level of traffic which complicates work during the day. The work requires the use of a gpr carriage that will be walked along the alignment of the sewer where accessible. This permit will be used in conjunction with the existing ddot blank permit #pa61550. 7pm to 3am
