A bill to amend the Housing and Community Development Act of 1974 for the purpose of providing guaranteed loans under title I of such Act to assist communities with a shortage of water supply.

Amends the Housing and Community Development Act of 1974 to authorize the Secretary of Housing and Urban Development to guarantee those obligations incurred by units of local government to finance activities necessary to alleviate a shortage or potential shortage of potable water where the Secretary determines available grant funding is insufficient. Enables such a guarantee to be made even if the application and/or the total outstanding debt of a unit of local government fails to meet statutory requirements.

Authorizes the Secretary to accept as security to assure repayment of such guaranteed debt: (1) a commitment by a local government to impose a unit surcharge on water; or (2) other financial resources of a local government.
