The Plumbing Engineer supports the Civil Engineer for the plumbing systems outside the building including storm water, sewer, natural gas, fire suppression water, domestic water, irrigation water, and other special water and waste systems.The plumbing engineer is involved in the whole building design of a water-based fire suppression system. In a typical facility the city water main will supply water for the fire suppression system. The plumbing engineer will need to coordinate with the civil engineer, water department, and fire department the details of connecting the fire water to the city water main.Automatic sprinkler systems are connected to the building standpipes that will supply water to the sprinkler heads distributed throughout the building. In taller building fire pumps are required to boost the city water pressure and flow to the fire department connections and sprinkler systems. The plumbing engineer plays a key role to include water demands for a sprinkler system with the water demands for a plumbing system.
