Service Reservoir. This distribution system serves all houses near Bowen Road and Stubbs Road between Flowerburn and Inland Lots Nos. 2302 and 2436. Formerly these houses below Bowen Road were supplied with unfiltered water from the Bowen Road Conduit and those above Bowen Road with filtered water from the Peak.
2,658 feet of 3″ wrought iron piping were laid from Middle Gap Reservoir to Bowen Road and 2,654 feet of 2″ wrought iron piping along Bowen Road to Inland Lot No. 2302 to supply this district.
The Mount Cameron Section has supplied filtered water continuously to the East end of the Peak since being put into use in April, thus relieving the load on the Pokfulum Road Pumping Station.
Since 1st July the Repulse Bay District has been supplied with filtered water from Jardine's Lookout Service Reservoir.

143. Stanley Water Supply:-The rapid development of this district and particularly the erection of the New Gaol, made the provision of an adequate filtered water supply essential.
The scheme adopted consists briefly of utilising the head in the existing pumping mains between Tytam Tuk Pumping Station and Tytam Gauge Basin to deliver water to a new service reservoir near Stanley Mound. The level of the Gauge Basin is approximately 400′ A.O.D. and the top water level of the new service reservoir 268′ A.O.D. The supply main is connected to two of the pumping mains near the pumping station, and the unfiltered water passed through pressure filters on its way to the service reservoir.
The pressure filter plant is situated near Tytam Tuk Pumping Station and consists of two 8'-0″ diameter Paterson pressure filters capable of filtering approximately 200,000 gallons per day, with provision for extension to approximately 300,000 gallons per day by the addition of one more filter.
Apparatus for the addition of a maximum of 75 grains of lime per gallon and 1½ grains of alumina per gallon to the ultimate quantity of 300,000 gallons per day of raw water has been included, and chlorine is injected into the filtered water main by a chlorine pump driven by a water motor. An air blower driven by an oil engine has been provided for the aeration of beds prior to washing, which is done by the back pressure of the filtered water.
The erection of the plant was carried out departmentally and was almost completed at the end of the year.
