For the purposes of sections 51A to 51D above, the definition of “water main” in section 219(1) below shall be treated as if the words “not being a pipe for the time being vested in a person other than the undertaker” were omitted.

In sections 51A to 51C above, references to so much of the service pipe as the undertaker could otherwise, by virtue of sections 45 to 51 above, be required to lay shall be construed disregarding section 46(8) above.

In this Act, references to vesting or the making of a declaration of vesting with respect to a service pipe refer to so much of the service pipe as is specified for those purposes in the relevant vesting agreement.
