Section 69.1504 - Hydraulic distribution system modeling recommended for fire protection(a) A Class A water public utility should develop and implement a plan to create, use and maintain a computerized hydraulic model for each discrete system as hydraulic distribution system modeling is a valuable aide in forecasting system capabilities under varying operational conditions.(b) The plan should address all of the following:(1) A determination of the minimum water system size, based upon the complexity of the distribution pipe network and water service requirements, that should have a model.(2) An identification of the commercially available hydraulic modeling software to be used.(3) A description of how data from the public utility's other informational databases and systems can be integrated into the computerized hydraulic model, including geographic information systems, supervisory control and data acquisition systems, and customer information systems.(4) A schedule by which the computerized hydraulic model will be calibrated, updated and maintained to ensure the accuracy is sufficient to reasonably predict a discrete system-s operational behavior to a determined level of accuracy set by the water public utility.Adopted by Pennsylvania Bulletin, Vol 54, No. 13.
