Van Milligen, City Manager FROM: Christopher Lester, Water Department Manager SUBJECT: Burlington Street Water Main Improvement Project 2023 Public Hearing DATE: July 31, 2023 INTRODUCTION The purpose of this memorandum is to request approval of the plans, specifications, form of contract and estimated cost for the Burlington Street Water Main Improvement Project 2023 through the adoption of the attached resolution. BACKGROUND Since 2004, the area in and around Burlington Street and National Street has been subject to eleven water main breaks, with six of those events occurring in the last three years. Not only are the residents inconvenienced with unplanned water outages, but also the water that comes to the surFace during the main breaks has resulted in some localized flooding of adjacent properties including property damage. The water main in Burlington Street is 1937 era 6" cast iron pipe and was installed with lead joints and at some locations buried deeper than normal to a depth of 9' 6". The street is unimproved with no storm sewer with an asphalt curb-line where it has been requested by the residents. The water main is heavily tuberculated and is fatigued due to internal corrosion resulting from the tuberculation which has resulted in a reduction of the pipe wall thickness and increased main breaks in recent years. The area is pressurized from the Park Hill Pumping Station which creates instantaneous pressure spikes leading to many of the main breaks experienced. In 2019, a capital improvement project was drafted to start the process of replacing fatigued pipe in the area in and around Burlington and National Streets, and to evaluate the performance of the Park Hill Pump Station. DISCUSSION While the initial scope focused on Burlington and National Streets, due to further main breaks in the adjacent streets including Muscatine, it was important to address the order in which mains would be replaced. To further our understanding of the impact of the pumping station and under what conditions cause the main breaks in the Burlington and National Street area, the Water Department purchased pressure recorders which were installed on hydrants. In September of 2021, the Water Department installed a pressure monitor on a hydrant at the intersection of Muscatine Street and Primrose Street which is near the proposed Burlington-National water main project site. The results of the collected data showed rapid pressure spikes as high as 115 psi and dips as low as 70 psi when the pumps at the Park Hill Pump Station were turned on and off creating water hammer in the pipes. The proposed project scope based on the data received from the pressure monitoring exercise is to replace approximately 820 feet of 6-inch water main along Burlington Street from Stoltz Street to National Street, to approximately 300-foot east of Primrose Street; and the installation of two air-release structures, one on Burlington Street and the second on Primrose Street. Additional capital improvements will be requested in future budget cycles for the continued replacement of water main along Muscatine Street. Park Hill Pumping Station improvement will be completed by in-house staff and are therefore not part of this scope.
