Operation Efficiency

Operation Efficiency

1,021 million m3 Annual Sewage Treatment Volume

The two major types of expenses in DSD in relation to providing wastewater and stormwater drainage services for the community are operational expenses and public works project expenses. Our day-to-day departmental operation is financed by the General Revenue Account of the Government, while funding for public works projects are approved on a project-by-project basis by the Finance Committee of the Legislative Council. To ensure public funds are used effectively, we strive to enhance operation efficiency by adopting new technologies and management practices.

Departmental Operating Expenditure

In 2013-14, the total expenditure of DSD was about 2.0 billion. Salaries accounted for about 794 million while the rest was contributed by other departmental expenses.

Our operating expenditure for the past five years is summarised below:

Capital Works Project Expenditure

We conduct regular reviews and updates on the cost estimate, including cashflow of capital works projects in various stages taking due account of the prevailing market condition and risk factors. A departmental committee has been established for vetting the project estimates for inclusion in the Legislative Council papers and examining the pre-tender estimates of works contracts before tender invitation. Upon funding approval, the project cost will be closely monitored against the Approved Project Estimate to ensure adequate funds will be available for completing the planned works. The Director of Drainage Services chairs regular meetings to monitor the progress of all major capital works projects and to ensure that the funds allocated are effectively expended.

Sewage Services Operating Accounts

The Sewage Services Charging Scheme (SSCS) was introduced on 1 April 1995 in accordance with the “Polluters Pay Principle”. Owners or occupants of premises connected to public sewerage network shall be required to pay the sewage services charges. To maintain a modest charging level, the scheme recovers only the operating and maintenance cost of public sewage facilities, while the construction cost is funded by public revenue.

Revenue and expenditure in the Sewage Services Operating Accounts for the past five years are summarised below:

  1. "Miscellaneous services" are excluded from the above calculation.
  2. Depreciation is not recovered through the Sewage Charge and Trade Effluent Surcharge.

Adjustment of the Sewage Charge

To enforce the "Polluter Pays Principle" and provide incentive to the public to conserve water resources, the Legislative Council approved a gradual increase of the sewage charge for 10 years starting from May 2007. Compared to the sewage charge rate of $1.20 per cubic metre of water supplied in 2007-08, the rate has been revised to $2.05 per cubic metre of water supplied in 2013-14 and will gradually increase to $2.92 on 1 April 2017 and onwards.
