Water Conservation and Drought Emergency Plan
Current Status - Voluntary
In accordance with the City's Drought Contingency and Emergency Water Plan, customers of the city's water system are asked to cut back on water usage from May 1 – September 30 by voluntarily watering once a week. The purpose of the plan is to conserve water and achieve reduction during peak demand. If there are higher demands on the system or a significant reduction in the lake capacity storage, mandatory restrictions will be announced. The revised water conservation plan also prohibits watering between the hours of 10 am and 6 pm anytime throughout the year. Residents with water wells are not required to comply with the prohibition of watering between 10 am and 6 pm but are encouraged to do so.
In order to better reflect the expanded water supply available to Coastal Bend customers rules for triggering water use restrictions during drought conditions have been revised. The easing of restrictions reflects the fact that water sources for the regional water system are now more diversified with surface water coming from the Colorado River and Lake Texana (on the Navidad River) in addition to Lake Corpus Christi and Choke Canyon Reservoir on the Nueces River. The rules eliminate the previous first stage which included voluntary water conservation measures.
Rules prohibiting lawn sprinkler use between 10 a.m. and 6 p.m. are always in effect regardless of any drought conditions.
Triggers under the regional Drought Contingency Plan are tied to the total amount of water in storage in Choke Canyon Reservoir and Lake Corpus Christi (CCR/LCC) combined. These are now referred to as Reservoir System Stages. The trigger for the Stage 1 condition is 40% of combined reservoir capacity.
Water use restrictions under Stage 1 now limit any sprinkler lawn watering to once per week on designated days and require customers to discontinue other non-essential uses.
Stage 2 is now triggered at CCR/LCC capacity of less than 30%. In Stage 2 drought conditions lawn watering is limited to once every other week on designated days.
Stage 3, which is considered a "critical" condition, is now triggered at an CCR/LCC capacity of less than 20%. At this level restrictions prohibit all watering of landscaping at all times. Rules prohibit filling pools and ponds and vehicle washing is limited. Violators can be disconnected from the water system. The rules seek to achieve an overall reduction in water demand of 30% or more in Stage 3.
Stage 4 would be an emergency condition such as a system outage or contamination event separate from lake levels.
The drought management restrictions adopted by the City of Corpus Christi apply to all customers of the regional system including those provided water through the San Patricio Municipal Water District. The District is required by contract to adopt a Drought Contingency Plan that is at least as restrictive as the plan adopted by the City.
The watering schedule is:
- Tuesday – Even numbered residences
- Wednesday – Odd numbered residences
- Thursday – Multifamily and commercial
Property owners using water wells, wastewater treatment plant effluent, or gray water for irrigation are exempt from the restrictions; however, the ordinance does require those users to post a sign stating the water used for irrigation is from a private well, wastewater treatment plant effluent, gray water or source other than the city's water supply. It is a separate violation to display a sign which falsely claims the water used to be from another source.
Rockport buys treated water from the San Patricio Municipal Water District (SPMWD) who, in turn, buys raw water from the City of Corpus Christi. SPMWD and the City of Corpus Christi implemented similar restrictions last week. The City's contract with SPMWD requires the City to follow SPMWD's plan.
The City of Rockport will continue to monitor lake levels and adjust the Plan's stage level as needed. For additional information on the Plan, click on the link below. Customers with questions are encouraged to contact the Public Works Department at (361) 790-1160.
