Chapter 8A — WATER CONSERVATION PLAN
Ontario Municipal Code · 2026-09 edition · updated 2026-09-30 · Ontario
Sec. 6-8.20. Scope and title.¶
This chapter shall be known as "The Water Conservation Plan of the City of Ontario." (§ 2, Ord. 2907, eff. June 16, 2009, as amended by § 2, Ord. 3027, eff. October 1, 2015 and § 2, Ord. 3196, eff. December 7, 2021)
Sec. 6-8.21. Statement of policy and declaration of purpose.¶
(a) Because of the water supply conditions prevailing in the City and/or the area from which the City obtains a portion of its supply, the general welfare requires that the water resources available to the City of Ontario be put to the maximum beneficial use to the extent to which they are capable, and that the waste or unreasonable use, or unreasonable method of use of water be prevented and that the conservation of such water be practiced with a view to that reasonable and beneficial use thereof in the interest of the people of the City. (b) The purpose of this chapter is to minimize the potential for a water shortage through the practice of water conservation, and to minimize the effect of a shortage of water supplies on the water customers of the City. It is furthermore the intent of this chapter to adopt provisions that will significantly reduce the inefficient consumption of water, thereby extending the available water resources necessary for domestic, sanitation, and fire protection of the community to the greatest extent possible. (c) This chapter shall be applicable to all persons within the City. For the purposes of this chapter, "person" means any natural person, property owner, renter, or lessee, as well as any corporation, partnership, government entity or subdivision, trust, estate, cooperative association, homeowners' association, joint venture, business entity, or other similar entity, or the property management company, property manager, agent, employee or representative of any of the above.
(§ 2, Ord. 2907, eff. June 16, 2009, as amended by § 2, Ord. 3027, eff. October 1, 2015 and § 2, Ord. 3196, eff. December 7, 2021)
Sec. 6-8.22. Authorization.¶
(a) The City Council may declare a water shortage based on a determination by the Metropolitan Water District of Southern California, the Inland Empire Utilities Agency, the declaration of an executive order of the Governor, or the adoption of voluntary or mandatory water use restrictions by any state agency governing the use of water, or based upon any interruption in water supply or delivery that the City Council determines in its sole discretion necessitates water conservation pursuant to this chapter. (b) In the event of an immediate emergency that causes an unplanned interruption of water supply, the City Manager or his/her designee is authorized to restrict water use and apportion the available supply of water among its customers in the most equitable manner possible to continue service fairly and without discrimination, except that preference shall be given to such service as is essential to the public interest and to the preservation of life and health. (c) A water shortage, including a water shortage emergency but excluding an immediate emergency, shall be declared by the adoption of a resolution of the City Council. (1) A notice of a water shortage, other than a water shortage emergency, shall be published in a daily newspaper of general circulation within the City. Any restrictions on the use of water during a declared water shortage shall become effective immediately upon such publication. (2) Notice of hearing to declare a water shortage emergency, other than an immediate emergency, shall be made in accordance with Water Code Section 351. Any restrictions on the use of water during a declared water shortage shall become effective immediately upon adoption unless otherwise be determined by the City Council. (§ 2, Ord. 2907, eff.
