DENIAL OF WATER: COMPLAINT.

(a) Any person entitled to receive or use water from any canal, ditch, flume, lateral, dam, reservoir, or lake or from any conserved or stored supply may present to the commission a written petition showing:

(1) that he is entitled to receive or use the water;

(2) that he is willing and able to pay a just and reasonable price for the water;

(3) that the party owning or controlling the water supply has water not contracted to others and available for the petitioner's use; and

(4) that the party owning or controlling the water supply fails or refuses to supply the available water to the petitioner, or that the price or rental demanded for the available water is not reasonable and just or is discriminatory.

(b) If the petition is accompanied by a deposit of $25, the executive director shall have a preliminary investigation of the complaint made and determine whether or not there are probable grounds for the complaint.

(c) If, after preliminary investigation, the executive director determines that probable grounds exist for the complaint, the commission shall enter an order setting a time and place for a hearing on the petition.

(d) The commission may require the complainant to make an additional deposit or execute a bond satisfactory to the commission in an amount fixed by the commission conditioned on the payment of all costs of the proceeding.

(e) At least 20 days before the date set for the hearing, the commission shall transmit by registered mail a certified copy of the petition and a certified copy of the hearing order to the person against whom the complaint is made.

(f) The commission shall hold a hearing on the complaint at the time and place stated in the order. It may hear evidence orally or by affidavit in support of or against the complaint, and it may hear arguments. The utility commission may participate in the hearing if necessary to present evidence on the price or rental demanded for the available water. On completion of the hearing, the commission shall render a written decision.

(g) If, after the preliminary investigation, the executive director determines that no probable grounds exist for the complaint, the executive director shall dismiss the complaint. The commission may either return the deposit or pay it into the State Treasury.
