Each year, over 50% of the water produced by AMWC is used for water landscaping, with most of this water being used in the four months between May and August. To help offset the significant stress placed on our limited water resources by landscape irrigation, AMWC offers a range of conservation programs and FREE information aimed at decreasing high summer water usage, and saving you money while conserving water in the landscape.​

AMWC Water Prohibitions

The California Water Resources Control Board has mandated that water agencies in San Luis Obispo County implement water restrictions due to the ongoing drought.  AMWC’s policy on the wise and beneficial use of water restricts certain wasteful practices.  AMWC will be sending notices to those shareholders who are observed to be wasting water reminding them to conserve

AMWC’s Board of Directors rescinded its declaration of a Stage 2 Water Shortage Condition due to recovery of groundwater levels in the Atascadero Basin resulting from this year’s above-average rainfall.  There are no longer any restrictions on overhead watering days.  However, the following prohibitions remain in place and are permanent, as ordered by the State Water Resource Control Board:


A. Plumbing leaks:  The escape of water through breaks or leaks within the water user’s plumbing or distribution system for any substantial period of time within which such break or leak should reasonably have been discovered and corrected is prohibited. 


B. Run-off from landscaped surfaces:  Watering of grass, lawns, ground-cover, shrubbery, open ground, crops and trees, including agricultural irrigation, in a manner or to an extent which allows substantial amounts of excess water to run off onto adjacent property, non-irrigated areas, private and public walkways, roadways, parking lots, or structures is prohibited.


C. Outdoor Watering Hours:  Overhead watering of grass, lawns, ground-cover, shrubbery, open ground, crops, and trees, including agricultural irrigation, between the hours of 10 a.m. and 5 p.m. is prohibited.


D. Irrigation After Rain Event:  Watering of outdoor landscapes during and up to 48 hours after measurable rainfall is prohibited.


E. Washing of hard-surfaced areas:  Washing down hard or paved surfaces, including but not limited to sidewalks, walkways, driveways, parking areas, tennis courts, patios or alleys, except under the following conditions, is prohibited: 1) to alleviate safety or sanitary hazards, and then only by use of a hand-held bucket or similar container, a hand-held hose equipped with a positive self-closing water shut-off device; or 2) if a low-volume, high-pressure cleaning machine or a low-volume high-pressure water broom is used.


F. Washing of Vehicles:  Using a hose that dispenses potable water to wash a motor vehicle is prohibited, except where the hose is fitted with a shut-off nozzle or device attached to it that causes it to cease dispensing water immediately when not in use.


G. Decorative Water Features:  The use of potable water in decorative water features that do not recirculate the water is prohibited.
