Every river purification authority shall include in the register maintained by them under subsection (7) of section 28 of the principal Act such particulars as the Secretary of State may by order prescribe of any conditions which have been imposed under this Act in relation to land or premises in their area, and of the other terms included in pursuance of this Act in any consent or notice; and paragraph (b) of the said subsection (7) shall apply in relation to a person charged with an offence under this Act as it applies in relation to a person charged with an offence under that section.

Any condition imposed under this Act or section 28 of the principal Act shall continue in force (subject to any variation under this Act or the said section 28) until revoked, and shall be binding on any person discharging effluent from the land or premises or, as the case may be, using the outlet to which the condition relates.

If the occupier of land or premises from which effluent passes or may pass to a stream by two or more ways meeting at the outlet, or a point short of the outlet, gives his consent for the purposes of this subsection, the power to impose conditions under this Act or section 28 of the principal Act as to effluent discharged from the land or premises shall thereafter (and notwithstanding any change of occupier) include power to impose conditions as to the nature and composition, temperature, volume or rate of discharge of effluent passing in each or any of those ways separately; and a consent given for the purposes of this subsection shall be recorded in the register under subsection (7) of the said section, but may be withdrawn by agreement with the river purification authority or on an appeal by agreement with the Secretary of State.

Any condition imposed under the said section 28 may be framed so as to have effect for a specified period or for a period beginning or ending with a specified date.
