The total quantity of water remaining in the reservoirs at the end of the year, inclusive of 39 million gallons in the low-level reservoir in course of construction, amounted to 629.70 million gallons.
The pumps at Tytam Tuk were in operation from 1st January until 31st March and from 22nd October until the end of the year (a total of 161 days). The quantity of water pumped by this plant amounted to 242.33 million gallons.
In addition to the permanent pumps already mentioned, the temporary pump, to which reference has been made in previous annual reports, was in use, with short intermissions, from 1st January until 9th April, the combined periods of pumping amounting to 97 days. The quantity of water pumped by it amounted to 46.93 million gallons. As the low-level dam in course of construction had reached the impounding stage, thus enabling the permanent pumps at Tytam Tuk, which are much more economical in their working, to deal with the water hitherto raised by the temporary pump, the latter was dismantled and returned to Store in November.
The gross quantity of water pumped during the year by both the permanent and temporary pumps amounted to 289.26 million gallons.
The following is a comparative statement of the cost of pumping during the years 1914 and 1915:
Tytam Tuk Pumping Station-Permanent Pumps 1914 1915 Coal, 5,454.35* 6,665.00† Wages, 4,066.70 4,138.20 Miscellaneous, including repairs and stores other than coal, 2,039.19 4,785.36 Total, $ 11,560.24 14,974.81* Exclusive of $6,900 expended in laying in a stock of coal to cover possible emergencies arising out of the war.
†This is the value of the coal consumed during the year. A stock of coal, valued at $6,286.25, was carried forward to 1916.
