Where a sewerage undertaker does not under section 107 above elect itself to make a communication to which a person is entitled under section 106 above or may not make such an election because of section 107(1A), the person making it shall—
before commencing the work, give reasonable notice to any person directed by the undertaker to superintend the carrying out of the work; and
afford any such person all reasonable facilities for superintending the carrying out of the work.
For the purpose—
of exercising his rights under section 106 above; or
of examining, repairing or renewing any drain or private sewer draining his premises into a public sewer,
the owner or occupier of any premises shall be entitled to exercise the same powers as, for the purpose of carrying out its functions, are conferred on a sewerage undertaker by sections 158 and 161(1) below.
The provisions of Part VI of this Act shall apply, with the necessary modifications, in relation to the power conferred by subsection (2) above as they apply in relation to the power conferred by sections 158 and 161(1) below.
