Fire Flow Analysis for Optimal Network Improvement
This paper describes the use of the City of Chilliwack's (British Columbia, Canada) water distribution system model to validate their proposed network upgrades. The City's water system supplies a population of 62,000 from seven water production wells. In total, over 1,500 pipes (approx. 410 km ranging in diameter from 25 mm to 750 mm), 17 pumps, 12 valves, 2 reservoirs, and 9 elevated tanks are included in the hydraulic network model. The hydraulic model was first calibrated as it is required for fire flow modeling applications. The objective of this study was then to review, validate and prioritize the proposed network upgrades which will improve fire flow capabilities of one particular area of the Chilliwack water system. Proposed improvements consisted of building a new tank, building a new pipe loop, and upgrading existing pipes. Four different scenarios were then defined and fire flow simulation runs were performed to compare the available fire flow at each junction node. The computed available flow which can be delivered to afire was compared with the required fire flow to determine the adequacy of the overall system. The critical node with the minimum pressure, for each fire flow calculation was also identified. The optimal pipe diameter was then determined which met the required available fire flow. This study demonstrated that a complex hydraulic network model can be used as a practical tool for the optimal planning of network upgrades. Enhancement of water distribution infrastructure planning, operation and management is a principal benefit of this study. This paper was presented at the 8th Annual Water Distribution Systems Analysis Symposium which was held with the generous support of Awwa Research Foundation (AwwaRF).
