GOAL

Achieve a 25% reduction in total gallons per capita per day. If circumstances warrant or if required by Dallas Water Utilities (“DWU”), city manager or official designee can set a goal for a greater water use reduction.

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 30% (70% depleted) of DWU’s share of the total conservation storage.

Water demand approaches system capacity

Water demand has reached or exceeded 98% of delivery capacity for 1 day.

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 Stage 2 and 3 requirements shall remain in effect during Stage 4 except:

ALL WATER CUSTOMERS

• All commercial and residential landscape watering is prohibited with the following exceptions:
  • Public gardens may water only between the hours of 9:00 p.m. and 9:00 a.m. once every five days based on the last digit of their address per the schedule in Stage 2.
  • Nurseries may water plant stock only between the hours of 9:00 p.m. and 9:00 a.m. once every five days based on the last digit of their address per the schedule in Stage 2.
  • Foundations may be watered for a two-hour period between the hours of 9:00 p.m. and 9:00 a.m. with a soaker or hand held hose on the five-day rotational basis prescribed for landscape watering in Stage 2.
• Any and all washing of vehicles is prohibited.
• All commercial water users may be required to reduce water consumption by a percentage determined by the director.

CITY GOVERNMENT

• Continue implementation of all restrictions from previous stages.
• 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 4 have been alleviated. If Stage 4 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 4 actions.
