General This design report will give an overview of the proposed water main extension for the proposed Resurrection Parish Catholic Church Expansion project on Lot 11A of the Tai Lane Addition, in Bozeman, MT. The report includes a description of the proposed water main extension and design parameters. The proposed improvements are anticipated to be constructed during the spring of 2012. Once the water main is constructed and approved, the main will become a part of the City of Bozeman system. The following references were used in the preparation of this report: a. COB Design Standards and Specifications Guide,2004. Addendum#3 b. COB Modifications to Montana Public Works Standard Specifications(MPWSS). Addendum#3 c. City adopted MPWSS and Adopted Addenda d. WQB Circular No. 1 e. City of Bozeman Zoning Map f. Uniform Plumbing Code B. Existing Water Supply The proposed water main extension will be served from the existing City of Bozeman water distribution system in Kagy Blvd. The following information regarding pressures of the existing system obtained from the City of Bozeman: Fire Hydrant#1921 — South 1 lth—approximately 100' south of Kagy Static Pressure: 75 psi Pitot Pressure: 55 psi Residual Pressure: 68 psi Hydrant Discharge Calculation—2.5 inch port, during test Qt= 167(pt).5 Qt= 167 x 555 Qt= 1,240 gpm Distribution Main Capacity—Fire flow at minimum residual pressure Qr=Qgp( '—py(Ps—Pt)]0.54 Q,= 1,240[(75 —20)/(75—55)]0.54 Q,=2,141 gpm Qt= Hydrant Discharge During Test Qr= Fire Flow at Residual Pressure PS= Static Pressure Pr = Minimum Residual Pressure Pt= Pitot Pressure Resurrection Catholic Church—Water Design Report Pagel of 3 C. Proposed Water System The proposed water main extension will consist of approximately 215 if of 8" Class 51 Ductile Iron Pipe, wrapped in poly wrap and connect to an existing 8-inch stub. The proposed main will terminate at a fire hydrant. Included in the appendix of this report is a plan and profile of the proposed water main. The layout of the proposed water main meets the City of Bozeman design criteria and will be located within a 30-foot wide water main easement. An existing public sanitary sewer main is located approximately 30-feet west of the proposed water main alignment. A fire hydrant will be installed at the end of main extension, fulfilling the distance requirement for fire hydrant spacing, as well as assisting in flushing of the main. A gate valve will be installed at the connection point to the existing 8-inch stub on Kagy Blvd. The water service line has been sized based on fixture units by the Mechanical Engineer and will be 1'/Z-inch copper service. A 4-inch fire suppression main is proposed to serve the Church. D. Capacity Analysis A capacity analysis was performed on the proposed water main extension. The water main extension has been designed to meet the maximum demand plus fire flow during the peak hour. The main extension will only serve the Church. A Hazen-Williams "C" Factor of 130 was used in the pipe evaluation. The working residual water pressure shall not be less than 20 psi at any point in the water distribution system under maximum day plus fire flow and the velocity shall not exceed 15 feet per second through the main. The existing Church is not currently served by domestic water and is not metered so no historic data is available. Based on information provided by the Mechanical Engineer, there will be 111.5 fixture units, equating to a maximum peak demand of 45 gpm. In addition to the peak hour demand, the water main must also be sized to provide for fire flow demand. Based on Appendix B of the 2009 International Fire Code, the minimum required fire flow and duration for a 17,600 sf Type V-B structure is 1,500 gpm for two hours. Based on a fire flow demand of 1,500 gpm the following Maximum Day and Peak Hour flows are shown in Table 1. TABLE 1 ANTICIPATED FLOWS Flow Designation Flow m Fire Flow m Flow m Maximum Day 15 1,500 1,515 Maximum Hour 45 1,500 1,545 Based on a fire flow demand and a maximum hour demand a maximum hour flow of 1545 gpm is required. Flow analysis of an 8-inch D.I. pipe with a C value of 130 can provide the required 1,545 gpm with a pressure drop of approximately 1.2 psi, from 75 psi to 73.8 psi, well above the Resurrection Catholic Church—Water Design Report Page 2 of 3 minimum of 20 psi. The pipe velocity at 1,545 gpm is 9.9 Vs. Capacity analysis calculations outlining the capacity of the proposed 8-inch pipe are included in the appendix of this report. E. Conclusion Based on this analysis, the proposed 8-inch water main extensions for the Resurrection Parish Expansion project provides adequate service to meet the,peak hour demand and fire flows for the development. This project will require the approval of the City Engineer and MDEQ.
