Maintenance of Water Works, Kowloon:-The year opened with a constant supply which was maintained until 6th February when it was considered advisable to restrict the supply to ten hours per day (6 a.m.-11 a.m. and 4 p.m.-9 p.m.) With the exception of five days during the Silver Jubilee Celebrations (5th-9th May) when a full supply was given, these hours were maintained until 22nd May, when it was found necessary further to restrict the supply to six hours per day (6-9 a.m. and 4.30-7.30 p.m.) On 18th June a constant supply was given and was maintained until 31st October. From 1st November to 31st December a fifteen hours supply was substituted (6 a.m.-9 p.m.) During the year therefore a constant supply was maintained on 177 days as compared with 365 days in 1934.
