64. Maintenance of City and Hill District Water Works.- Owing to deficient rainfall during 1922 the year opened with the Rider Mains in operation in all Rider Main Areas.
As the Spring rains were deficient and late in arriving, apart from four days during Chinese New Year, it was not possible to give a full supply until the 13th of August following the very heavy rains on the 6th of the same month.
Exceptionally heavy typhoon rains were experienced in August, and by the end of the month the storage reservoirs were full.
On the 4th September, owing to the collapse of retaining walls of adjacent houses, the Bowen Road Conduit was carried away below Lots 2237 and 2238, and it was therefore found necessary to resort again to a restricted supply in the Western Rider Main Areas until the 6th October when temporary repairs had been completed.
On 31st October, exceptionally heavy rains were again experienced, as a result of which the temporary conduit at Bowen Road was once more damaged by a landslide necessitating recourse to Rider Main Supplies in the Western Rider Main Districts until 7th November when full supply in all Districts was restored and maintained until the end of the year.
The total quantity of water stored in the impounding reservoirs on the 1st January amounted to 1,089 million gallons, there being 395 million gallons in the gravitation reservoirs and 694 million gallons in the low-level reservoirs requiring pumping. Storage reached a minimum on the 1st of June when the total was 359 million gallons, there being 104 million gallons in the gravitation reservoirs.
