Section 3
Sec. 3. The total investment on any projects constructed under the provisions of this Act, together with interest at the rate of four per centum per annum on the unpaid balance thereof, shall be reimbursable out of the net income from the operation of such markets, slaughterhouses or waterworks as the case may be. In case the net income is not sufficient to cover the annual reimbursement and interest, the deficiency shall be covered from the regular income of the province, municipality, or city concerned. The expenses for preliminary surveys and investigations of projects which are eventually abandoned will be borne by the province, municipality, or city concerned.
