Ms. Sue Polka June 2, 2017 Page 5 RECOMMENDATIONS - Storage: The north pressure zone currently needs approximately 500,000 gallons of additional storage at this time to supply a 3 hour fire demand during a maximum day demand. The existing storage capacity is not even adequate to supply the average day demand of the north pressure zone. The projected storage capacity needed for the future north pressure zone system with full development of the TCAAP site is approximately 1.5 million gallons. This will require approximately one million gallons of additional storage capacity to be constructed in the north pressure zone. The completion of a one million gallon elevated storage tank is recommended by 2019 according to the water storage calculations presented in Table 1. A 1 MG water tower usually requires approximately 2 years to design, bid, and construct. Therefore, the City should begin the planning process for the proposed water tower as soon as possible. - Booster Station: Currently, the existing east side booster station’s firm capacity exceeds the north pressure zone’s maximum daily demands, indicating that the existing water system is adequately sized for the current system demands. With the projected growth and development of the TCAAP site, an additional west side booster station will be required to meet the future projected demands of the North pressure zone. The booster station should be designed, bid, and constructed in conjunction with the proposed TCAAP water tower, if possible, since both of these improvements are needed to serve the proposed development. A second booster station is also recommended to provide redundancy for the existing booster station. - Water Distribution System: The existing North and South pressure zone water distribution systems were modeled in addition to the future North pressure zone water distribution system. Modeling results indicate that the existing water system has the capacity to meet normal operational water demands and fire flows throughout the service area. For future development, the modeling results depict that expansion of the existing system in the north pressure zone will require at least two connections to the south pressure zone to serve the proposed TCAAP site. Two 12-inch connections will be required to meet projected water demands and provide adequate fire flows. The modeling results also indicate that an altitude valve will be required for the existing North Tower following the construction of the proposed TCAAP Tower. The proposed improvements are shown on Figure 4.
