INTER-OFFICE MEMORANDUM DEPARTMENT OF PUBLIC WORKS DIVISION OF ENGINEERING TO:Board of Public Works FROM: Becca Plantz, Project Engineer SUBJECT: Mackey Drive Pump Station –Lafayette Falls Emergency Repair DATE:October 2, 2020 In 2018, a small pump/grinder station was installed as a temporary sewer connection for two (2) residential properties on Mackey Drive. At the time, these homes fronted an inactive sewer due to the ongoing and phased work related to the subdivision development. On September 21, 2020, the Sewer Department received a complaint about a foul odor coming from the field adjacent to the pump/grinder station. The Sewer Department investigated the structure, concluded the pump failed, and set up bypass pumping equipment to resolve the issue. During bypass setup and exchanging an extension cord, the failed pump kicked back on but turned off again overnight. Engineering confirmed that the pump had failed. It was critical to replace the failed pump immediately so sewer crews could remove their temporary equipment from the undeveloped lot. Our internal crews do not replace pumps and future subdivision development (next phase) would not take place in a timely enough manner. R&R Excavating initially installed the pump and grinder in 2018, so I requested their services on Friday, September 25, 2020 to investigate and replace the pump if necessary. With emergency approval confirmed, a crew from R&R mobilized on Monday morning September 28, 2020 to clean the structures, remove, and replace the pump. The Emergency project cost was $2,942.15.
