When a barge acci- dent on December 19, 2017 dumped 467,000 gallons (5.1 million pounds) of a liquid fertilizer called urea ammonium nitrate in the Ohio River near Cincinnati, Louisville Water employees sprang into action without hesitation. Scientists, plant operators, and engineers determined a plan of action to keep the water safe, which included a never-before extended shutdown of approxi- mately 11 hours of the intake pumps at Zorn Pumping Station and a slight adjustment to the water treatment strategy. This spill was unique in that we couldn’t see it on the river; scientists had to sample the water downstream from the spill to determine the length of the plume. Using the river’s flow rate and continuous sampling, we mapped a projected travel time to our water intakes. Several employees worked around the clock, even on Christ- mas Eve and Christmas Day, to ensure the safety of our drinking water. As the plume began passing by our Zorn Pumping Station on Christmas Day, we were able to close the intakes since the holiday is one of the lowest pumping days of the year. At the treatment plant, we monitored levels and maintained the high water quality our customers expect. That commitment to quality is a 24/7 focus. Louisville Water con- tinues to produce some of the highest quality water in the United States. We maintained the Phase IV Partnership for Safe Water, Scientists Chris Bobay and Mark Campbell work in a mobile lab and on the Ohio River to track the spill. 2 2017 AT A GLANCE 24,125 FIRE 53,374 VALVES HYDRANTS a distinction that only 16 of the nation’s approximately 55,000 water utilities have earned. Both of our treatment plants have the Phase IV status which puts Louisville Water in an elite class of utilities. In the Field Louisville Water employees working in the field met high stan- dards for quality, safety and efficiency throughout 2017. We completed Phase 1 and started Phase 2A of a three-year, $25 million project to replace a 1930 cast iron main along Eastern Parkway. This project—the largest replacement project in our history—uses a slip-lining technique, which involves installing a 42-inch outer diameter steel pipe inside the original 48-inch pipe. Slip-lining significantly minimizes environmental impacts and neighborhood disruptions while increasing the lifespan of this critical main. Customers along the route do not lose water service during the construction. In addition to the engineering aspect, the project has included a significant communication effort. From social media, neighbor- hood meetings, and construction signage to website updates and emails, Louisville Water continuously sent information on the project to more than two dozen stakeholder groups and thou- sands of commuters and residents. Crews dig pits and push a new pipe inside the original 1930 pipe on By the end of 2017, we had completed sidewalk and landscape Eastern Parkway. restoration from the first phase. Louisville Water also donated funds to neighborhood associations and Louisville Metro Parks to purchase and plant trees in the neighborhood. 3 2017 AT A GLANCE WATER MAIN NUMBER OF BREAKS 12.7 MAIN BREAKS 536 PER 100 MILES OF PIPE When complete, Louisville Water will have slip-lined 6.4 miles of the water main. Replacing Lead Lines Louisville Water has made significant progress in replacing its remaining lead service lines. In 2017, crews and contractors re- placed an average of four lead service lines daily, which puts the company on track to eliminate our remaining lead lines by 2020. Louisville Water has budgeted roughly $23.6 million to complete the work. Lead is not a public health concern for Louisville’s drinking water.
