Before commencing the construction of a specified work the Company shall procure at its expense in liaison with and to the reasonable satisfaction of the Agency a survey of any drainage work liable to be affected by that specified work.

Subject to sub-paragraph (3), the Company shall, from the commencement of the construction of the specified works and except to the extent that any approval given by the Agency under this Part of this Schedule permits otherwise, maintain in good repair and condition and free from obstruction any drainage work which is situated within the limits of deviation and on land owned by the Company or of which it otherwise has control or is in occupation for the purposes of or in connection with the specified works, whether or not the drainage work is constructed under the powers of this Order or is already in existence.

The obligation imposed on the Company under sub-paragraph (2) does not apply where the Agency or another person other than the Company is liable to maintain the drainage work in question and is not precluded by the exercise of the powers of this Order from doing so.

If any drainage work referred to in sub-paragraph (2) is not maintained in good repair and condition and free from obstruction the Agency may by notice in writing require the Company to repair and restore that drainage work, or any part of it, or (if the Company so elects and the Agency in writing consents, such consent not to be unreasonably withheld), to remove the drainage work and restore the site (including sea defences) to its former condition, to such extent and within such limits as the Agency reasonably requires.

If, within a reasonable period being not less than 28 days beginning with the date on which a notice under sub-paragraph (4) is served on the Company, it has failed to begin taking steps to comply with the reasonable requirements of the notice and thereafter completed them within such reasonable period as may be specified in the notice, the Agency may do what is necessary for such compliance and may recover any expenditure reasonably incurred by it in so doing from the Company.

In the event of any dispute as to the reasonableness of any requirement of a notice served under sub-paragraph (4), the Agency shall not, except in an emergency, exercise the powers conferred by sub-paragraph (5) until the dispute has been finally determined.
