cover any trade effluent surcharge that may become due and a deposit under this section is in addition to any deposit
required under section 3.

payment of the deposit, the Drainage Authority may notify the Water Authority that payment has not been received
and, on being so notified, the Water Authority may exercise his powers under section 19(2) of the Waterworks

(8) Where a consumer has been paying a trade effluent surcharge based on being in a particular category as
prescribed by the regulations and he subsequently changes his trade, business or manufacture to which the trade
effluent surcharge relates such that he would be in a different category as prescribed under the regulations, he shall as
soon as practicable on changing such trade, business or manufacture notify the Drainage Authority of the change
giving details of the change sufficient for the Drainage Authority to identify the change in category for the purposes of
calculating the trade effluent surcharge that would be payable.

(9) A person who fails to notify the Drainage Authority of a change as required under subsection (8) commits
an offence and is liable on conviction to a fine at level 6.
