205. With the rapid increase in population distribution difficulties continued even although an extensive mainlaying programme was carried out. This was due to the fact that large areas of the city are still served by old mains and service reservoirs of inadequate size to meet the increased density of population and many more new mains and increased service reservoir capacity are still required. Filtration capacity also proved inadequate and an attempt to maintain full supply in July had to be abandoned as the demand for water far exceeded the capacity of the filters as well as of the distribution system. The completion of the new rapid gravity filters at Eastern (Stubbs Road) (see paragraph 226 of last year's Report) in November improved the position somewhat in regard to filtration but filter capacity will still be inadequate to maintain full supply during the next hot season if the population remains at its present level.
206. The purity of the water was maintained at a high standard, the majority of samples tested showing B. Coli absent in 100 c.c. Isolated cases of local pollution occurred and remedial measures were carried out.
207. Waste detection continued by house to house inspection only, no staff being available to operate the waste detection meter system. The preparation of the detailed plans necessary for the operation of this system was, however, in hand at the close of the year.
208. The position in regard to the repair of water meters continued to be satisfactory although handicapped in Kowloon by the lack of proper workshop facilities. Approval was given, however, towards the end of the year for a new workshop in Kowloon.
209. Survey work and stream gaugings for the Tai Lam Chung Valley Scheme continued, but approval to proceed with the Scheme was still withheld.
210. To meet the demand for water by the Military Authorities in the Fanling area a new Intake and Filters were constructed on the River Jhelum near Hok Tau Village and about five miles of pipe line laid to the Fanling cross roads.
211. New slow sand filters were constructed at Wong Nei Chong Reservoir so that filtered water could be supplied to the Shou Son Hill area. All Island districts supplied from the Waterworks now have a filtered supply.
