         Unitywater does not guarantee that fire fighting flow will be available at all times on the grounds
         that components of Unitywater’s water supply infrastructure may be shut down temporarily for
         planned maintenance or to repair bursts or damage caused by others.

         The current type of use for this property is attached housing. Hence, in accordance with Table
         1 above, the Minimum Standard of Service that applies is 15 litres/second at 12 m residual
         head.

         Current Dynamic Model Data
         Unitywater’s current dynamic water supply model indicates the following under a demand
         condition of 2/3 of the estimated maximum hour demand on the peak day in Year 2031.

         Unitywater reserves the right, at any time, to change the operating pressures within the water
         supply network, but not below the Minimum Standard of Service stated in Table 1.

         Unitywater accepts no liability whatsoever for changes in the operating pressure of this water
         supply network and the consequent impacts on any fire suppression system within the subject
         property. It shall be the property owner’s responsibility to ensure that any fire suppression
         system operating on the property complies with the relevant requirement of the Building Code
         of Australia and that this system is regularly tested for compliance with the relevant standards.
         Any upgrade of the fire suppression system required due to changes in the operating pressure
         of the water supply network will be the property owner’s responsibility.

         Suggested Approach to Design of Fire Suppression System
         It is suggested that the owner of the property consult with a qualified and suitably experienced
         hydraulic designer to consider the risks associated with designing a fire suppression system
         for the subject property based upon the output from Unitywater’s current dynamic water supply
         model. Unitywater may alter the operating pressure of the network at any time.

         It is suggested that this risk should be balanced against the cost of designing and installing a
         fire suppression system that would provide the desired level of performance when supplied
         with water from Unitywater’s mains at the Minimum Standard of Service stated in Table 1.
