Milligan Water Supply Corporation Drought Contingency and Water Emergency Response Plan December 2008 1. INTRODUCTION AND OBJECTIVES The measures included in this Drought Contingency and Water Emergency Response Plan are intended to provide short-term water savings during drought or emergency conditions. Water savings associated with ongoing, long-term strategies are discussed in the Water Conservation Plan. The purpose of this drought contingency and water emergency response plan is as follows: To conserve the available water supply in times of drought and emergency. To maintain supplies for domestic water use, sanitation, and fire protection To protect and preserve public health, welfare, and safety To minimize the adverse impacts of water supply shortages To minimize the adverse impacts of emergency water supply conditions A drought is defined as an extended period of time when an area receives insufficient amounts of rainfall to replenish the water supply, causing water supply sources, in this case reservoirs to be depleted. In the absence of drought response measurers, water demands tend to increase during a drought due to the need of additional outdoor irrigation. The severity of the drought depends on the degree of depletion of supplies and on the relationship of demand to available supplies. The NTMWD considers a drought to end when all of its supply reservoirs refill to the conservation storage pool. 2. DROUGHT CONTINGENCY AND WATER EMERGENCY RESPONSE STAGES AND MEASURERS STAGE 1 Initiation and Termination Conditions for Stage 1 The NTMWD has initiated Stage 1, which may be initiated due to one or more of the following; The NTMWD Executive Director, with the concurrence of the NTMWD Board of Directors, finds that conditions warrant the declaration of Stage 1. Water demand is projected to approach the limit of the permitted supply. The storage in Lavon Lake is less than 65% of the total conservation pool capacity. NTMWD’s storage in Jim Chapman Lake is less than 65% of the NTMWD’s total conservation pool capacity. The Sabine River Authority has indicated that its Upper Basin water supplies used by NTMWD (Lake Tawakoni and/or Lake Fork) are in a Mild Drought. NTMWD has concern that Lake Texoma, the Ease Fork Raw Water Supply Project, or some other NTMWD source may be limited in availability in the next 6 months. NTMWD water demands exceeds 90% of the amount that can be delivered to customers for three consecutive days. Water demands for all or part of NTMWD’s delivery system approaches delivery capacity because delivery capacity is inadequate. NTMWD’s supply source becomes contaminated. NTMWD’s water supply system is unable to deliver water due to the failure or damage of major water system components. Suppliers water demand exceeds 90% of the amount that can be delivered to customers for three consecutive days. Supplier’s water demand for all or part of the delivery system approaches delivery capacity is inadequate. Supply source becomes contaminated. Supplier’s water supply system is unable to deliver water due to the failure or damage of major waer system components. Supplier’s individual plan me be implemented if other criteria dictate. Stage 1 may terminate when NTMWD terminates its Stage 1 condition or when the circumstances that caused the initiation of Stage 1 no longer prevail. Goal for Use Reduction and Actions Available under Stage 1 Stage 1 is intended to raise public awareness of potential drought or water emergency problems. The goal for water use reduction under Stage 1 is a two percent reduction in the amount of water produced by NTMWD. The General Manager or Board of Directors may order the implementation of any of the actions listed below, as deemed necessary: Request voluntary reductions in water use by the public and by wholesale customers. Notify wholesale customers of actions being taken and request implementation of similar procedures. Increase public education efforts on ways to reduce water use. Review the problems that caused the initiation of Stage 1. Intensify efforts on leak detection and repair. Reduce non-essential city government water use( Examples include street cleaning, vehicle washing, operation of ornamental fountains, etc.) Notify major water users and work with them to achieve voluntary water use reductions. Reduce city government water use for landscape irrigation. Ask the public to follow voluntary landscape watering schedules. STAGE 2 Initiation and Termination Conditions for Stage 2 The NTMWD has initiated Stage 2, which may be initiated due to one or more of the following: The NTMWD Executive Director, with the concurrence of the NTMWD Board of Directors, finds that conditions warrant the declaration of Stage 2.

Compliance with this plan cannot be accomplished due to technical or other limitations. Alternative methods that achieve the same level of reduction in water use can be implemented. Variances shall be granted or denied at the discretion of the General Manager or Board of Directors. All petitions for variances should be in writing and should include the following information: Name and address of the petitioners Purpose of the water use Specific provisions from which the relief is requested Detailed statement of the adverse effect of the provision from which relief is requested Description of the relief requested Period of time for which the variance is sought Alternative measurers that will be taken to reduce water use Other pertinent information 2.2 Procedures for enforcing Mandatory Water Use Restrictions Mandatory water use restrictions may be imposed in Stage 2, 3, and 4 Drought contingency and water emergency response stages. The Penalties associated with the mandatory water use restrictions are as follows: On the first violation, Members will be given a written warning that they have violated the mandatory water use restriction. On the second violation and subsequent violations, citations may be issued to Members, with minimum and maximum fines established by the Board of Directors. After two violations have occurred, MWSC may install a flow restrictor in the line to limit the amount of water that may pass through the meter in a 24-hr period. After three violations beyond initial written warning have occurred, MWSC may cut off water service to the customer. Penalties for Violations 1st Violation- Written Warning 2nd Violation- $100.00 fine, plus possible flow restrictor installed if determined to be necessary. 3rd Violation- $250.00 fine 4th Violation- $450.00 fine and disconnection of service until case may be reviewed by General Manager and Board of Directors. 2.3 Coordination with the Regional water planning group and NTMWD MWSC will send a copy of this plan to NTMWD. |
