Today, with nearly 425,000 custom- ers and the capacity to supply up to 200 million gallons of water per day, WaterOne serves customers in 17 cit- ies throughout Johnson County. The utility also serves unincorporated parts of the county and its service connections extend into parts of Wy- andotte County and Miami County. WaterOne is able to grow to meet the demand by following a comprehen- sive master plan. The organization makes continual investments in infra- structure at the right time. " Typically we follow the " Nessie" model guidelines. That 's a planning model , an infrastructure replacement tool that originated in Australia," Cart- er said. " The curve, years over dollars, visually looks like the hump of the Lochness Monster, hence the Nessie curve. It comes down to looking at your system and determining that you need to be replacing so much of the infrastructure over so much time. The curve allows you to estimate how many dollars per foot for each type of pipe. Then you can build your pro - gram from there. It 's a great planning and budgeting tool ." WaterOne plans to install more than 10 miles of replacement main this year with upward of two miles of that through pipe bursting . The rest will be installed through a combination of other trenchless methods like direc- tional drilling , as well as traditional construction methods.

According to WaterOne's Kevin Carter, the utility has six, five-member crews that work on construction are capable of operating the static pipe bursting system.
