Steps Texas needs to take to improve water planning

Our state’s water policies have evolved dramatically over the past 15 years, generally in a positive direction. This is evidenced by the growing acceptance of water conservation as an important means of addressing water demands. However, the current State Water Plan and water planning process do not fully take advantage of water conservation and drought response and fail to adequately address the needs of fish, wildlife and the environment.

The Texas Living Waters Project recommends that the State improves state water planning by embracing the following strategic and cost-effective approaches to meeting critical water needs:

Revise water demand projections

Currently, the State bases its water demand projections on the amount of water that would be needed during the drought of record to meet all the same water demands that exist during wet years. This approach needs to be refined.

Moving forward, projections should be revised to reflect actual water needs, rather than the various water “demands” that may be unrealistic to meet in future drought years. The current method leads to excessive water demand projects, over planning and excessive cost estimates. Simply incorporating rational drought management into the water planning process will lead to more realistic and cost effective plans for regions and the state as a whole.

In addition, when the Texas Water Development Board develops its population and water demand projections, the board needs to closely evaluate the relationship between the cost of water and its effect on long-term demand. The current planning process often treats demand as a static concept and does not adjust forecasts to account for rising water prices or changes in patterns of water use beyond basic plumbing code changes.

One positive step is that new water demand projections now include the expected savings from new efficiency standards for clothes washers and dishwashers.

Plan for all water needs

The State Water Plan should be revised to include all types of water needs – including the need for water to support the health of our rivers and bays as well as commercial and recreational fishing, river and coastal tourism, and other businesses that depend on healthy and productive rivers and bays for their survival.

Failing to plan to meet those environmental water needs results in an incomplete water plan that threatens our natural heritage. The Texas Water Development Board and the regional water planning groups must recognize and include water for healthy rivers and bays as a valid user group whose needs are planned for and met.

When evaluating proposed new water supply projects, the current water plans assume that some level of environmental flow restriction will be included in any new surface water permit to help limit the harm caused. Although that is an appropriate reflection of existing law, it doesn’t begin to assess the extent to which increased use of water under existing permits and projects will harm the health of rivers and bays or what proactive measures are needed to keep them healthy.

Consider the energy-water nexus

The push for energy efficiency is accelerating, and reliance on non-water-using renewable energy sources such as wind and solar power is expanding. Because almost 50% of all U.S. water withdrawals are for power generation, ensuring accurate projections in this area is critical for long-term water planning.

Prepare for a changing climate

Climate change will likely have an increased impact on traditional water management strategies. The 2012 State Water Plan proposes $53 billion worth of water management strategies, most of which are likely to be adversely impacted by hydrologic changes associated with climate change. The 2012 State Water Plan includes a discussion about future climate variability and acknowledges the need for additional study to better understand likely impacts of a changing climate on water availability in various parts of Texas. However, it is unclear from that discussion if such studies will be undertaken in order to better inform planning assumptions.

The Texas Water Development Board and the regional water planning groups need to address the issue of climate change and prepare state and regional water plans based on an acknowledgement that:

  • Climate change is happening and it may have a profound effect on our water resources.
  • Addressing climate change requires creative and innovative approaches not bound by traditional assumptions, and water supply strategies should be reviewed for susceptibility to climate impacts.
  • Climate change may significantly affect population and growth trends.
  • Realistic projections of the impacts of climate change and of options for responding to them are essential and must be adequately funded.

Adopt a strategic funding approach

The State should establish clear metrics for determining which water infrastructure projects in the State Water Plan merit state financial assistance. Whatever the ultimate source of state funds may be, it is essential to establish an effective screening process so that money is used efficiently. The metrics should reflect the following principles:

  • Priority consideration should go to water supply projects designed to meet near-term needs that cannot reasonably be met through improved water efficiency measures.
  • Prioritization criteria should reward projects that are highly cost effective, include measures to ensure the new water supply will be used efficiently, and result in low environmental impact.
  • There must be a firm commitment for substantial funding from local and regional water supply interests and a demonstration that full funding from those interests is not feasible (absent extenuating circumstances).
  • In the case of groundwater projects, assistance should only be provided to projects clearly shown not to indirectly impair existing water supply sources, including spring flows or river flows.

In addition, any ongoing state water funding mechanism should dedicate a reasonable amount of funds to implement voluntary, on-the-ground measures to help keep rivers flowing and provide freshwater inflows to bays and estuaries. Any funding mechanism should also ensure that one-third of available funds are actually used for the implementation of effective water conservation programs and water reuse projects, with no more than half of that money allocated to reuse.

House Bill 4, passed in the spring 2013 and approved by voters that fall, calls for devoting at least one-fifth of funding for conservation and reuse. That is a good start, but a concerted effort is needed to make that proposed allocation a reality and to ensure that programs to improve actual water efficiency are not short-changed in favor of reuse projects.
