Water Distribution System Hydraulic Model Calibration and System Evaluation Report <br /> Chapter 7 – Conclusions and Recommendations <br /> December 2019 <br /> <br /> <br />P05049-2019-000 Page 21 <br /> <br />CHAPTER 7 CONCLUSIONS AND RECOMMENDATIONS <br />The hydraulic model is a dynamic tool for planning the direction of Arden Hills’ water <br />distribution system and can be used to support policymakers with multi-million-dollar decisions <br />to address infrastructure needs. The calibrated hydraulic model can also assist engineers and <br />planners in analyzing hydraulic performance for the purposes of planning and design. In <br />addition, it is a valuable tool for system operators in meeting the day-to-day operation and <br />maintenance needs for the utility. Given the potential for service area growth and with the Rice <br />Creek Commons development on the horizon, the Arden Hills distribution system could see <br />significant additions going forward. As such, the hydraulic model should be continuously <br />updated and evolve in response to the changes made within the water distribution system <br />network, as well as with the changes in the system demands. <br />7.1 Future Uses of the Hydraulic Model <br />For the City of Arden Hills, the following outline identifies several ways the calibrated <br />hydraulic model can be applied to planning, design, and operation activities in the future. <br />Planning Tool – Develop a Master Plan <br />x Address issues associated with existing system deficiencies <br />o Water system pressure <br />o Distribution system storage <br />o Water main capacity <br />o Water main reliability <br />o Fire flow analysis <br />x Address issues associated with system growth <br />o Incorporate updated land use plan <br />o Evaluate 10, 20, 30-year growth <br />o Develop a plan for future improvements <br />o Identify capital improvement projects & costs <br />ƒ Water main improvements for system expansion <br />ƒ Future water storage locations and sizes <br />ƒ Future transmission pipeline extensions
