Body
SUMMARY & BACKGROUND:
The Bay View Pump Station (BVPS) pumps combined sewage to the Treatment Plant and the Wet Weather Facilities located at the Water Reclamation Plant. The sewage pumps are protected by three large Headworks barscreens. Barscreen #1 was severely damaged during the heavy rain storm on July 31st, 2018. The barscreen was taken out of service, which reduced the pumping capacity of the BVPS by 35%. Further investigation revealed inadequate installation was the cause of the failure. Barscreens #2 and #3 were also inspected and found to have various degrees of installation problems. The Division contacted area contractors looking for a contractor to handle the emergency repairs. Mosser Construction, Inc. was selected, because they had the resources to expedite the emergency repairs. The work was started in September 2018, and included the cleaning of the wet well; cutting a section of the roof; the removal, repair, and reinstallation of the barscreen; and the replacement of all supports. The barscreen had to be transported to Houston, TX for repair/replacement of components and testing. The barscreen was repaired and placed back in service in March 2019. The Division decided to have Mosser Construction, Inc. perform similar work on Barscreens #2 and #3 to avoid future problems. All three barscreens were tested and commissioned before they were placed in service.
