Caution: This is a past version. See the current version here.

(1) Where a consumer or agent believes that-

   (a)  the CODs of trade effluent discharged from his premises is less than
        the CODs specified in column 4 of Schedule 2 for the relevant trade,
        business or manufacture; or

   (b)  the difference between the CODt and the CODs of trade effluent
        discharged from his premises is less than the difference between the
        CODt specified in column 3 and the CODs specified in column 4 of
        Schedule 2 for the relevant trade, business or manufacture, he may, at
        his own expense, have his trade effluent tested by an approved
        laboratory in accordance with the technical memorandum issued by the
        Secretary for Works and submit the results to the Drainage Authority
        together with any other relevant information that the Drainage
        Authority requires.

(2) Where the Drainage Authority is satisfied that the CODs is less than the
CODs in column 4 of Schedule 2 for the relevant trade, business or manufacture
or the difference between the CODt and the CODs is less than the difference
between the CODt in column 3 and the CODs in column 4 of Schedule 2 for the
relevant trade, business or manufacture, he shall determine a new trade
effluent surcharge rate using the applicable matrix in Part I or II of
Schedule 4.

(3) A trade effluent surcharge rate determined under subsection (2) shall take
effect from the beginning of the billing period during which such
determination was made and shall be in effect for 1 year at which time the
rate established under section 3 shall apply subject to the consumer or agent
having further tests done under subsection (1) and the Drainage Authority
making another determination under this section.

(4) Where tests performed under this section show that trade effluent being
discharged is equal in strength to, or less in strength than, the
strength of domestic sewage, the Drainage Authority shall not impose a trade
effluent surcharge for a period of 1 year in accordance with subsection (3).
