End
Background:
Holloway, Updike, and Bellen, Inc., was retained by BAMA to design the referenced project. The construction of the project will result in the installation of manually cleaned bar screens/baskets at five high flow sanitary sewer lift stations (Old Adams Creek, Adams Creek Northwest, The Greens, Indian Springs, and Timberbrook). These new bar screens/baskets will offer protection of the existing pumps, which have been damaged in the past by debris in sewage flows.
