Projects and Actions

Most Groundwater Sustainability Agencies will need to increase supply, manage demand, or do both to achieve sustainable groundwater management under SGMA. 
Below are some potential actions that a GSA may undertake:

Increase Supply

GROUNDWATER RECHARGE

Groundwater recharge describes natural or artificial replenishment of an aquifer. Recharge can occur naturally through precipitation, runoff or surface water infiltration or artificially via spreading basins, injection wells, and irrigation return flow.

CONJUNCTIVE USE

Conjunctive use refers to the coordinated management of both surface and groundwater resources as a single source. Reliance on groundwater in dry in years is offset by managed recharge of aquifers in year with above average precipitation.

STORMWATER
CAPTURE

Once thought of as a nuisance, stormwater is now being seen as a source for recharging depleted groundwater basins.

RECYCLED
WATER

Wastewater can be treated and used as a source of water for groundwater recharge or landscape irrigation.

Reduce Demand

AGRICULTURAL WATER USE EFFICIENCY

Agricultural water efficiency has increased as a result of improvements in irrigation infrastructure, the integration of real-time monitoring, and a better understanding of crop water requirements.

URBAN WATER
USE EFFICIENCY

Tiered water rates, outdoor water use regulations, landscape efficiency programs, and rebates on efficient indoor appliances are some of the tools being used by cities to reduce consumption.

MARKETS AND
TRADING

Water markets can provide flexibility in managing water supplies. Markets are sometimes referred to as trading, transfers, credit programs, banking, or exchanges.

WATER ALLOCATION SYSTEMS

In some basins, GSAs may choose to develop groundwater allocation schemes to manage demand and ensure that GSPs meet their sustainability goal and avoid state intervention.
