A reference in Part I of this Act to the construction of a sewer includes a reference to the extension of an existing sewer.
For the purposes of sections 64(2) and 66(1) above, a building or proposed building—
is not deemed to have a sufficient water supply available unless—
it has a sufficient supply of water laid on, or
such a supply can be laid on to it from a point within 100 feet of the site of the building or proposed building, and the intervening land is land through which the owner of the building or proposed building is, or will be, entitled to lay a communication pipe, and
is not deemed to have a sewer available unless—
there is within 100 feet of the site of the building or proposed building, and at a level that makes it reasonably practicable to construct a drain to communicate with it, a public sewer or other sewer that the owner of the building or proposed building is, or will be, entitled to use, and
the intervening land is land through which he is entitled to construct a drain.
The limit of 100 feet does not apply, for the purposes of subsection (2) above, if the local authority undertake to bear so much of the expenses reasonably incurred in—
constructing, and maintaining and repairing, a drain to communicate with a sewer, or
laying, and maintaining and repairing, a pipe for the purpose of obtaining a supply of water,
as the case may be, as is attributable of the fact that the distance of the sewer, or of the point from which a supply of water can be laid on, exceeds 100 feet.
