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.

Sewage Services Operating Cost Recovery Rate

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.

Sewage services cost recovery rates in 2012-13 and 2013-14 are tabulated below:

  Total
2012-13 2013-14
Revenue of Sewage Charge and Trade Effluent Surcharge ($M) 983 1,096
Expenditure (excluding depreciation) of Sewage Charge and Trade Effluent Surcharge ($M) 1,498 1,544
Operating Cost Recovery Rate (%) 65.6 69.0

Notes:

  1. "Miscellaneous services" are excluded from the above calculation.
  2. Depreciation is not recovered through the Sewage Charge and Trade Effluent Surcharge.
  3. The 2013-14 figures are provisional and subject to endorsement by the Sewage Services Accounts Committee.
