Small types of aggregate increased to such an extent that the productive capacity of the existing quarry installations was exceeded and it was found necessary to let two small contracts for the supply of this type of material.
181. With the exception of the installation of the crushers and compressors, delivery of which has been delayed, the reconstruction of Tsat Tse Mui Quarry was completed during the year. The foundations for this machinery have already been laid and, pending delivery which is expected in the course of the next few months, arrangements have been made to install old crushers as a temporary expedient.
182. A contract for the removal of the overburden was let and the work was practically completed by the end of the year, good use being made of this material in the North Point Reclamation Scheme.
183. The output at Hok Un Quarry, which is the main source of supply for the mainland, increased considerably, and the overall cost of production has, as a result, been reduced considerably.
184. The small quarry at Hung Shui Kiu has been operated satisfactorily and the output of rubble and crushed aggregate, although limited, has proved of value in this area of the New Territories.
185. The following table shows the output of all types of quarry products compared with that for the previous year:

186. Undoubtedly the most important aspect of the water supply of the Colony during 1950/51 was the ever-increasing consumption. With no addition to the resources during the year, the further increase in consumption resulted in still greater restrictions in the hours of supply,
