Groundwater recharge is the process of replenishing groundwater aquifers with surface water from various sources such as storm water and rivers. This process is essential for maintaining a sustainable groundwater supply.
Conjunctive use is the integrated management of both surface water and groundwater resources to effectively deliver reliable water supply. While TID relies on surface water deliveries for our growers, the District will charge the groundwater aquifer when water is available and pump groundwater during times of drought – when surface water is in lower supply.
The TID Board of Directors has approved the implementation of certain Groundwater Recharge Projects when water is available. Idle Lands Groundwater Recharge has been approved for the 2024 Irrigation Season.
Idle lands that have existing connections to our canals are encouraged to flood irrigate to improve groundwater conditions. An example of an idle land would be an orchard that was removed for replanting in the future. Instead of letting the land sit unused, growers can irrigate free of charge.
