(a) The board of school directors in any school district may, in the manner herein provided, enter into any contract with any person, firm, association, or corporation, for the furnishing of light, heat, or water to such school district, for any term not exceeding five years. The amount to become due and payable thereon, under such contract, may be distributed equally during the years over which the same extends, and only so much thereof as becomes due and payable in any one year need be provided for in the annual estimate of school expenses for any school year, and be certified to by any school controller.

(b) In any case where any school building to be supplied with water is not sufficiently near to the pipe lines of any water company to enable the school district to avail itself of such supply and another source of supply is available nearer to such school building, the board of school directors may acquire such supply, or any part thereof deemed necessary, and may lay and construct a pipe line to convey water from such source of supply to such school building, and, for such purpose, may enter upon, occupy and use any highway or public or private property which it deems necessary. In the event that compensation therefor cannot be agreed upon with any owner of private property so acquired, occupied and used, the amount thereof shall be determined in the manner provided in sections seven hundred twenty-one to seven hundred twenty-eight, both inclusive, of this article.

(c) In any case where a school district has constructed a water pipe line for the supply of water to any school building and such supply is more than adequate for such purpose, the board of school directors may, subject to such terms as may be agreed on, permit the tapping of such pipe line by any adjacent community having no other available public water supply.
