Drought Contingency Plan

Smart water management is important to the longevity of a community. Learn about the Drought Contingency Plan about how each stage affects your household water use.

STAGE 1: Voluntary Water Awareness

Goal: Raise public awareness of potential drought problems. Achieve a 5% reduction in water use through voluntary water conservation by residents, businesses, and Addison.

Actions: Specific actions taken during any drought situation will be determined by the City Manager. The City Manager may also take other actions not listed, if deemed necessary. Following is a menu of possible actions:

ALL WATER CUSTOMERS:

  1. Encourage reduction in water use
  2. Prohibit residential or commercial lawn watering and car washing between the hours of 9am and 8pm

CITY GOVERNMENT:

  • Initiate public education campaign teaching and encouraging reduced water practices
  • Implement reduction in city use of landscape watering
  • Reduce city government use of water for street washing, vehicle washing, operation of ornamental fountains and all other nonessential use
  • Intensify normal leak detection and repair activities on water pipes and mains
  • City staff will begin review of the problems which initiated Stage 1 actions
  • Notify major water users and work with them to achieve voluntary water use reduction

Triggering Criteria: The Town purchases 100% of its potable water from the City of Dallas. Addison has implemented its Drought Contingency Plan, and in doing so, is following the same emergency water management triggering criteria as the City of Dallas:  

  • Water supplies are low
  • Water demand approaches system capacity
  • Short-term deficiencies limit supply capability
  • Contamination

Termination Criteria: All initiated actions will remain in effect until the conditions which triggered Stage 1 have been alleviated.

 

STAGE 2: Mandatory Water Watch

Goal: Achieve a 10% reduction in total gallons per capita per day. 

Triggering Criteria: The Town purchases 100% of its potable water from the City of Dallas. Therefore, the emergency water management triggering measures will be the same as those of the City of Dallas. Water Awareness may be triggered by any one of the following: 

  • Water supplies are low. Total raw water supply in connected lakes or the western or eastern reservoirs has dropped below 55% (45% depleted) of DWU’s share of the total conservation storage.
  • Water demand approaches system capacity. Water demand has reached or exceeded 90% of delivery capacity for 3 consecutive days. 
  • Short-term deficiencies limit supply capability. Water demand approaches a reduced delivery capacity for all or part of the system, as determined by DWU and or emergencies specific to the Town of Addison. 
  • Contamination. Natural or man-made contamination of the water supply source(s) occurs. 

Actions available: Specific actions taken during any drought situation will be determined the City Manager or the official designee. The City Manager may also take other actions not listed, if deemed necessary. Following is a menu of possible actions:

ALL WATER CUSTOMERS:

  • Prohibit hosing off of paved areas, buildings or windows; operation of swimming pool draining followed by refilling, washing or rinsing vehicles by hose; using water in such a manner as to allow runoff or other water wastes. EXCEPTIONS: Vehicles may be washed or rinsed with a hose at commercial car washes; vehicles may be washed at any location with a bucket or other container.
  • Limit landscape watering at each service address to once every five days based on the last digit of the address per the schedule below. 
Last Digit of Address Allowed Water Dates
0 and 5 5th, 10th, 15th, 20th, 25th, 30th
1 and 6 1st, 6th, 11th, 16th, 21st, 26th
2 and 7 2nd, 7th, 12th, 17th, 22nd, 27th
3 and 8 3rd, 8th, 13th, 18th, 23rd, 28th
4 and 9 4th, 9th, 14th, 19th, 24th, 29th

No watering will be allowed on the 31st. Apartments, office building complexes or other property containing multiple addresses will be identified by the lowest address number.

Where there are no numbers, a number will be assigned by the director. These restrictions also apply to government facilities.

Exemptions: Foundations, azaleas, and new plantings (first year) of trees and shrubs may be watered with a hand-held or soaker hose on any day for up to two hours; nurseries may water plant stock only without restrictions; public gardens may water without restriction.  

CITY GOVERNMENT:

  • Continue public education campaign teaching and encouraging reduced water use practices.

Termination Criteria: All initiated actions will remain in effect until the conditions which triggered Stage 2 have been alleviated. If Stage 2 is initiated because of excessive demands, all initiated actions will remain in effect through September 30 of the year in which they were triggered, or until the director of Dallas Water Utilities determines that conditions exist which will allow removal of Stage 2 actions.

 

STAGE 3: Mandatory Water Warning

Goal: Achieve a 20% reduction in total gallons per capita per day. 

Triggering Criteria: The Town purchases 100% of its potable water from the City of Dallas. Therefore, the emergency water management triggering measures will be the same as those of the City of Dallas. Water Awareness may be triggered by any one of the following: 

  • Water supplies are low. Total raw water supply in connected lakes or the western or eastern reservoirs has dropped below 45% (55% depleted) of DWU’s share of the total conservation storage.
  • Water demand approaches system capacity. Water demand has reached or exceeded 95% of delivery capacity for 2 consecutive days. 
  • Short-term deficiencies limit supply capability. Water demand approaches a reduced delivery capacity for all or part of the system, as determined by DWU and or emergencies specific to the Town of Addison. 
  • Contamination. Natural or man-made contamination of the water supply source(s) occurs. 

Actions available: Specific actions taken during any drought situation will be determined the City Manager or the official designee. The City Manager may also take other actions not listed, if deemed necessary. Following is a menu of possible actions. All requirements of Stage 2 shall remain in effect during Stage 3, with the addition of:
