WATER SYSTEM MASTER PLAN 11. STORAGE CAPACITY EVALUATION
The District uses water supplied from both storage and wells to help meet peak demands. In this section District operational, emergency, and fire storage criteria is reviewed. Pumping and storage facilities are evaluated and sized to meet the District’s requirements under demand conditions including maximum day, maximum day plus fire flow, and peak hour. This section includes a description of the storage capacity evaluation methodology and the results of the evaluation. The storage capacity evaluation for McClellan Business Park is presented in Appendix A.
11.1 Storage Criteria
Distribution storage facilities are designed to provide the recommended volume of water to equalize the pumping rate of water supply facilities or booster stations during the projected peak demand event. The volume of water necessary for fire protection needs is also evaluated. The total storage capacity volume may be reduced by a system’s production and supply facilities that have sufficient standby power equipment. This includes wells. Storage facilities need to: Provide operational storage to supply peak hour demands. Provide fire storage and fire flow to meet fire flow requirements. Provide emergency storage. In this analysis the total treated water storage capacity requirements for 2035 is evaluated based on operational storage, fire storage, and emergency storage requirements per the District’s standard operational and performance criteria in Table 10-1 of this plan. These evaluation criteria including the three storage capacity requirements are defined as follows: Maximum day demand is the largest daily water use that occurs over the given year. The 2035 maximum day demand for each pressure zone is based on the analysis in Section 3. A maximum day to average day multiplier is developed in Section 3. Peak hour demand is the peak hour flow that occurs on the maximum day. A peak hour to maximum day multiplier is defined in
