Water Resources Management
Types Of Droughts
- Limits on withdrawals by community water systems due to sensitive aquatic habitats
- Restrictions on the locking of barges;
- Modification to the amounts of water released from reservoirs;
- Bans on illegal water withdrawals by golf courses above municipal water intakes;
- Additional water treatment to control taste and odour caused by aquatic plant growth;
- Water use restrictions banning lawn watering and other outside uses by approximately 30 community water systems;
- Extension of public water mains and lines to unserved areas
Water Resources Management Planning
The traditional Approach
Integrated Water Resource Management (IWRM Plan)
Computation of Demand-supply Gap
For this we have to compute water resources availability and water supply requirement.
Computation of Water resources availability * Net Surface water available in the area * Net Ground water available in the area * Total water available 2. Computation of Water Demand
Drought Management Plan
Manage Wastewater Discharges
IWRM will require that wastewater discharges and releases from reservoirs be controlled to minimize risks to public health and the environment in times of drought. Alternative reservoir operating guides might be established based on various drought-related triggering conditions. Permits might be issued based on drought vulnerability whereby operations might be interruptible and /or additional treatment required.
Provide Guidance on Community Water Systems’ Drought Management Plans
TDEC has developed a guidance document on the necessary elements of a drought management plan for community water systems. The purpose of the guide is to promote and increase preparedness so that a drought’s adverse impacts would be mitigated. The guidance includes suggested drought management planning steps. TDEC will review each system’s drought management plan, prioritizing those that have experienced drought issues in the past.
