Wat. Code, § 31141

(a) A district may adopt ordinances relating to the provision of sanitation services and the regulation of those services. Every such ordinance shall be in full force and effect immediately upon adoption, but shall be published once in full in a newspaper of general circulation, printed, published and circulated in the district within 10 days after adoption, or if there be no such newspaper it shall be posted within 10 days after adoption in three public places within the district.

(b) The publication of ordinances, as required by subdivision (a), may be satisfied by either of the following actions:

(1) The district may publish a summary of a proposed ordinance or proposed amendment to an existing ordinance. The summary shall be prepared by an official designated by the board. A summary shall be published and a certified copy of the full text of the proposed ordinance or proposed amendment shall be posted in the office of the board at least five days prior to the board meeting at which the proposed ordinance or amendment or alteration thereto is to be adopted. Within 15 days after adoption of the ordinance or amendment, the board shall publish a summary of the ordinance or amendment with the names of those directors voting for and against the ordinance or amendment and the official shall post in the office of the board a certified copy of the full text of the adopted ordinance or amendment along with the names of those directors voting for and against the ordinance or amendment.

(2) If the official designated by the board determines that it is not feasible to prepare a fair and adequate summary of the proposed or adopted ordinance or amendment, and if the board so orders, a display advertisement of at least one-quarter of a page in a newspaper of general circulation in the county shall be published at least five days prior to the board meeting at which the proposed ordinance or amendment or alteration thereto is to be adopted. Within 15 days after adoption of the ordinance or amendment, a display advertisement of at least one-quarter of a page shall be published. The advertisement shall indicate the general nature of, and provide information about, the proposed or adopted ordinance or amendment, including information sufficient to enable the public to obtain copies of the complete text of the ordinance or amendment, and the names of those directors voting for and against the ordinance or amendment.
