Although there has been some upgrading of the system since the Town's establishment to make it comply with current standards, a severe water supply problem exists in some areas of the town due to inadequate pressure within the reticulation system. Over the past few years this situation has deteriorated to such an extent that some consumers have no water during daily periods of peak demand towards the end of each dry season. A current, comprehensive water supply system layout for the Town (including correct fire hydrant locations and Water Division's proposed 1985 additions to the system) is included in Appendix A - drawings A-I to A-4. 4.1 Supply Source: Batchelor (#5 and town water 16) located Town's and #4) perimeter, and located within is drawn primarily from two bores along the Batchelor Road on the three supplementary bores (#2, #3 the town centre. 4.2 Reservoir and Rising Main: The Town's storage requirements are facilitated by a 1.12 ML reinforced concrete reservoir (approximately 10.5 metres diameter and 13 metres high).The reservoir is located to the east of the Town, approximately 2.2 kms from the town centre at an A.H.D. level of 120.9 metres a~ bottom water level. Ground surface levels in the Town vary from RL 99 to RL 107. Water is diameter and #4 pumped from bores #5 and #6 via a 225 AC rising main to the reservoir. cores #2, pump to the reservoir via a 150 mm diameter rising main. 4.3 Trunk Mains : From the reservoir, a 225 mm diameter AC gravity main feeds a 150 mm diameter AC town ring-main. Other town mains are generally 100 mm diameter AC except for alSO mm diameter AC main 1n Mardango Street while 100 mm diameter uPVC mains have been constructed in Naranga, Turana, and Wondaree Streets. A diagram of the existing system is shown in Appendix A. 4.4 Service connections : The original service lines were galvanized iron, and these have been replaced as became necessary, with either copper or uPVC. Apparently, no records have been kept-of these replacements. 4
