Distribution Section
10.13. Work continued on distribution mains extensions to serve new development. Undersized or defective mains were replaced and alterations were made, as necessary, to facilitate road construction work. In all, approximately 50 miles of mains were laid as extensions to the fresh and salt water distribution systems by this section.
Waste Detection Section
10.14. Systematic waste detection continued throughout the year. Quarterly checks were carried out in 159 fresh water areas and annual checks in 9 salt water areas. A number of major leaks were discovered and repaired resulting in an estimated daily saving of nearly four million gallons of water.
House Service Section
10.15. With the increased building development and the provision of metered individual connections to rooms in the Mark III and Mark IV resettlement blocks there was a 62% increase in the number of new meters installed compared with the year 1968-69.

# CONSTRUCTION DIVISION
Chief Engineer:
H. J. WOODTHORPE, C.Eng., M.I.C.E., M.I.Mun.E., A.M.I.W.E. Li Hin-wing, B.Sc. (Lond.), C.Eng., M.I.C.E. (Acting)
10.16. The Division is responsible for designing, preparing contracts for and supervising the construction of all new water supply projects, other than schemes executed by consulting engineers and certain minor works carried out by the Distribution Division.
10.17. The reduced expenditure of $8.77 million (a decrease of over $18 million compared with the previous year) was due to the completion of a number of large schemes last year, and a preponderance of smaller schemes this year.
10.18. The works completed comprised six fresh water and three salt water service reservoirs, two fresh water and three salt water pumping stations, 16.2 miles of fresh water mains over 6" diameter, including 2.2 miles over 21 ins. diameter, and 3.2 miles of salt water mains ranging from 10 ins. to 27 ins. diameter.
