Cal. Wat. Code § 56082
The board may issue and sell the bonds of the district at not less than par value, and the proceeds shall be placed in the treasury of the county. Before selling the bonds, or any part thereof, the legislative body shall give notice not less than 10 days prior to the date of sale by publication pursuant to Section 6061 of the Government Code in a newspaper of general circulation circulating in the district inviting sealed bids in such manner as the legislative body shall prescribe. If satisfactory bids are received, the bonds offered for sale shall be awarded to the highest responsible bidder. If no bids are received, or if the legislative body determines that the bids received are not satisfactory as to price or responsibility of the bidders, the legislative body may reject all bids received, if any, and either readvertise or sell the bonds at private sale.
All premiums and accrued interest received shall be paid into the fund to be used for the payment of principal and interest on the bonds and the remainder of the proceeds of the sale shall be paid into the construction fund of the district, and proper records of the transactions shall be placed upon the books of the treasurer.
