As groundwater availability shapes future development, communities are diversifying water supplies and investing in flexible infrastructure to support sustainable growth
Texas is one of the fastest-growing regions in the U.S., with nine of its cities listed among the top 20 for population and economic growth in the country. But as communities across Texas continue to grow, they face mounting pressure to balance development with sustainable groundwater management.
Desired Future Conditions (DFCs) are groundwater management goals created to ensure the long-term sustainability of groundwater resources across Texas. DFCs help determine how much groundwater can be extracted in many parts of the state, making proactive water planning more important than ever. DFCs influence water supply decisions and the strategies communities use to support future growth.

What Are Desired Future Conditions (DFCs)?
Desired future conditions (DFCs) are an important groundwater management tool for the Texas Water Development Board’s long-term water planning process. They are long-term targets established by local groundwater managers that define desired groundwater conditions within an aquifer to meet the needs of future generations while continuing to support current water demands. Factors such as groundwater levels, spring flow rates, and the volume of water stored in an aquifer help determine how much groundwater can be withdrawn without compromising the aquifer’s long-term health, reliability, and sustainability. Once established, DFCs provide the foundation for groundwater permitting, groundwater availability estimates, and long-term water planning.
Groundwater Conservation Districts (GCDs) are local agencies tasked with developing and implementing groundwater management plans for their areas, which need to be approved by the Texas Water Development Board. GCDs are responsible for the day-to-day management of groundwater within their jurisdictions, and work closely with water users to conserve, protect, and manage groundwater resources while balancing the water needs of their communities.
GCDs work together through regional planning groups known as Groundwater Management Areas (GMAs). Texas has 16 GMAs, each made up of representatives from multiple GCDs that manage the same aquifers. Because aquifers often extend across district boundaries, GMAs coordinate long-term planning at the regional level. Their primary responsibility is to develop and adopt DFCs for the aquifers within their management areas.
While GCDs and GMAs work closely together, their roles are distinct. GCDs are responsible for local groundwater management, including monitoring aquifer conditions, issuing permits, and enforcing groundwater regulations. GMAs, on the other hand, focus on regional planning by bringing neighboring GCDs together to establish shared Desired Future Conditions that support the long-term sustainability of the aquifers they collectively manage.
Why DFCs Matter for Growing Communities
While DFCs play an important role in conserving groundwater and ensuring the long-term sustainability of aquifers for future use, they also present some drawbacks, particularly for growing communities.
Limits on groundwater withdrawals can reduce the amount of water available to support new development. Without sufficient water capacity available to meet growing demand, new development may become more difficult or require alternative water supplies, and industries may not be able to expand. When supplies are limited, there may also be long-term water security concerns, which can deter potential investors and prompt them to look elsewhere for less restricted, more reliable water supplies.
However, from a planning perspective, because DFCs help determine how much groundwater can be sustainably withdrawn from an aquifer, they provide valuable insight into the long-term water availability for new homes, businesses, and industries. For residential and commercial developments, understanding future groundwater availability can help determine whether alternative sources and additional infrastructure will be needed. By providing a clearer picture of future groundwater availability, DFCs enable communities to make more informed decisions about water infrastructure investments, land use, and economic development.
As groundwater availability becomes more constrained under long-term planning targets, many communities are evaluating alternative water sources that place less demand on freshwater aquifers.
Expanding Water Supplies Beyond Traditional Groundwater
To overcome groundwater limitations and meet growing water demand, Texas communities need to look beyond traditional groundwater sources and explore alternatives. By diversifying their water supply, communities can not only reduce their dependence on a sole water source, but also build resilience to drought and changing groundwater availability while supporting future growth.
Brackish water desalination offers a promising and feasible solution for many Texas communities. Texas has large volumes of brackish groundwater held in underground aquifers that can be treated with brackish water reverse osmosis (BWRO) to provide a reliable source of potable water to support growth while reducing pressure on freshwater aquifers.
Communities can also invest in decentralized water treatment systems that treat locally available water sources closer to where the water will be used. Decentralized treatment allows communities to use these local sources, including groundwater, surface water, and reclaimed water, reducing the need to transport treated water over long distances.
One of the most sustainable strategies that communities can invest in is water reuse. Wherever water is used, wastewater is generated. This wastewater can be reclaimed, treated, and recycled for nonpotable use or, with additional treatment, potable applications, providing a reliable source of water that can take pressure off freshwater supplies.
Building Flexible Infrastructure for Long-Term Growth
Identifying alternative water supplies is the first step to enhancing water security. The next step is to invest in treatment infrastructure that can keep pace with growing demand.
Rather than building oversized treatment plants based on growth projections that could take years to materialize, many communities are opting for scalable treatment systems that allow capacity to be installed in phases that align with population growth. This approach reduces the upfront capital investment required for large infrastructure projects that may not be fully utilized for many years while still allowing communities to respond to evolving water demands.
Alternative delivery models, including Water-as-a-Service®, plant leasing, build-own-operate (BOO), and public-private partnerships, are helping communities gain swift access to advanced treatment systems, without the financial and operating burdens typically associated with large infrastructure projects.
Planning Today for Tomorrow’s Water Needs
The aim of DFCs is not to stifle development, but to help communities better understand their available water resources so they can plan for growth more sustainably. By exploring alternative water sources, diversifying water supplies, and investing in flexible infrastructure that can adapt to evolving demands, communities can enhance their water security and be better positioned to accommodate future residents, businesses, and economic development.
