Note : With the declaration of the entire HK territory under Water Control Zones on 1 April 1996, trades with Chemical Oxygen Demand values higher than 2000 g/m3 are assumed to have reduced their wastewater strength to 2000 g/m3. The above TES rates are based on the reduced COD values.

8. Restaurants
Note : For a trade, business or manufacture listed above, the amount of TES charged is equal to 80% of the volume of water supplied, other than water supplied specifically for flushing purposes, multiplied by the corresponding rate in Table G2.


Variation of Sewage Charges
A non-domestic consumer can apply for a reduction of SC or TES if the consumer can demonstrate that the volume of wastewater discharged into the public sewerage system is not more than 85% of the volume of water on which the SC or TES is based.

A consumer liable to pay TES can apply for a variation of the TES rate for his premises by having the pollution level of the trade effluent discharged reassessed at his own expense by an approved laboratory in accordance with the Technical Memorandum issued by the Secretary for Works. Upon the satisfactory completion of the reassessment, a revised TES rate will be determined according to the charging matrix shown in Table G4 and will take effect for one year.

Note : When using this matrix the following conditions should be applied to the COD values :
(i) If COD total > 2000 g/m3 then COD total = 2000 g/m3; and
(ii) If COD settled > 2000 g/m3 then COD settled = 2000 g/m3
