STAFF REPORT TO:Mayor Keis and Members of City Council FROM:Bill Dircks, Public Works Director DATE:August 1, 2018 RE:Emergency Water Tower Repairs As you are aware, the water tower needed to be drained a couple of weeks ago in order to replace a failed gasket at the manway hatch on the riser pipe. Since the tower had to be drained and it was year five of our maintenance agreement with SEH, the interior bowl of the tower was also inspected and touched up as necessary per the terms of the agreement. The work was completed on Friday, July 27, the tower was disinfected, and the refilling process was started. While the tower was refilling, the public works staff heard dripping inside the tower. Classic Protective Coatings was able to respond on Friday afternoon and they determined that there was a cracked weld where the riser pipe meets the bottom of the bowl. Classic was able to get a crew on site on Tuesday, July 31 to repair the welds. They repaired a thirty- inch section on the outside of the bowl and a seven-inch section inside the bowl. Following the work, the tank was cleaned and disinfected once again and the refilling process started again. Barring any additional emergencies, the tower should be back in service by early next week. The emergency repair of the cracked welds does not fall under the scope of the maintenance agreement between Little Canada and SEH. The preliminary price for the work provided by SEH was $6,450. That price may change based on the actual work performed. SEH did provide us with discounted pricing due to our status as a maintenance client. Staff recommends the Council approve the expenditure in the range of $6,450 from the Water and Sewer Capital Budget for emergency water tower repairs. The final price will hopefully be known by the meeting on Wednesday.
