64. Maintenance of City and Hill District Water Works.* --The year opened with constant supply in force throughout the City and Hill District and this was maintained until the autumn, when, unfortunately, owing to the deficient rainfall during the wet season, it was found necessary to have recourse to restrictive measures. The position of affairs was so serious in September, all the reservoirs being then below overflow level, that it was found necessary to resort to street fountains for supplying the Rider Main Districts, the supply available being inadequate to warrant the application of the rider main system. Supply by street fountains was accordingly introduced on the 24th September and it remained in force up to the close of the year. Anxiety with regard to the possibility of maintaining this system of supply throughout the dry season was fortunately removed by the exceptional rainfall which occurred in October, when 11.71 inches of rain fell, as compared with an average of 4.91 inches. As has been previously explained, under the street fountain system, a constant supply is available, the people being able to obtain water from the fountains at any time during the 24 hours instead of, as happens under the rider main system, receiving in their houses a supply, -- in many cases inadequate, -- during only two or three hours daily.
A valuable addition to the available supply was afforded by the low-level reservoir in course of construction which was sufficiently advanced to admit of the impound of 51 million gallons of water towards the close of the year.
The quantity of water stored in the impounding reservoirs on the 1st January amounted to 660.788 million gallons and it reached a minimum on the 12th May when it amounted to 208.27 million gallons.
The reservoirs were at or over their permanent overflow levels for the following periods:
