What type of water supply is typically required for sprinkler systems?

The requirement for a combination of municipal supply and on-site tank for sprinkler systems is grounded in the need for both reliability and redundancy in water supply. Municipal water supplies are often used due to their consistent pressure and flow rates, which are essential for ensuring that sprinklers can operate effectively in case of a fire. However, relying solely on a municipal supply can be risky, as it may be subject to interruptions due to maintenance, supply line issues, or during high-demand situations.

Having an on-site tank complements the municipal supply by providing an additional volume of water that can be readily available in times when the municipal source is inadequate or when quick access to water is critical. This combination enhances the reliability of the fire protection system, ensuring that sufficient water flow is available to meet the demands of the sprinkler system even in adverse conditions. It allows for greater flexibility in design, accommodating different building needs and configurations while enhancing protection against fire threats. The integration of both sources is seen as best practice in the design and installation of sprinkler systems to ensure consistent performance and safety.
