[highlight8.gif] 1,001 million m3 Annual Sewage Treatment Volume

The operation of our Department is funded by the General Revenue Account and the Capital Works Reserve Fund. Our Department's operating expenditure is met directly from the General Revenue Account which is the Government's main account and acts as the central funding device, while the Capital Works Reserve Fund was set up to finance public works programmes, acquisition of land, capital subventions and major systems and equipment items. To optimise the use of public funds, we always enhance our sewerage and stormwater drainage services in a cost-effective and environmentally responsible manner.

Departmental Operating Expenditure

In 2012-13, the total expenditure of our Department was about $1.9 billion. Of this allocation, salaries accounted for about $770 million, with the rest being contributed by departmental expenses and capital items.

A Summary for the past five years of our operating expenditure is highlighted below:

Capital Works Project Expenditure

In general, we have to conduct the Capital Works Resource Allocation Exercise annually to estimate the project expenses for all the capital works. We need to update and well document the cost estimate including cashflow of a project in all stages taking due account of the prevailing market rates and risk factors. Our Department also maintains a departmental committee for vetting the project estimates for inclusion in the LegCo Public Works Subcommittee papers and the vetting of pre-tender estimates of all works contracts, including term contracts. The cost estimate of a project will be closely monitored against the Approved Project Estimate and the administrative cap imposed by the Financial Services and the Treasury Bureau to ensure adequate funds for completing the approved works are available. In addition, we have a committee chaired by the Director 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' was introduced on 1 April 1995 according to the "Polluter Pays" Principle. All premises connected to public sewers are required to pay the sewage services charges. The charges were set to recover only the operating and maintenance costs of the public sewage facilities, while the capital costs of building these facilities will continue to be borne by the Government.

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

Adjustment of Sewage Services Charge

To enhance the "Polluter Pays" Principle and to encourage the public to conserve valuable water, the Legislative Council has approved a gradual increase of the sewage charge for 10 years starting from 1 April 2008. Since that day, the sewage charge rate was revised from the original $1.20 to $1.31 per cubic metre of water supplied. The rate is and then gradually increased by 9.3 per cent per annum until reaching $2.92 per cubic metre on 1 April 2017.
