This project consisted of expanding the state-of-the-art 4MGD membrane ﬁltration system to 8MGD under a Construction Manager At-Risk Contract. The Scope included building a new lab and ofﬁce area in the existing treatment building. The Harper Team installed two (2) additional membrane ﬁltration systems with associated equipment. The Team also performed signiﬁcant upgrades to the chemical storage and feed systems and installed new plate settlers, sludge collection and ﬂocculators in the sediment basin behind the plant. Regular communication with the Design Team and Owner allowed the project to be completed under budget and within the specified schedule.
