South Dakota Expands Water Infrastructure Plans

By Scout Nelson

South Dakota has long depended on rivers, reservoirs, and underground aquifers to meet its water needs. These resources have supported steady growth in population, agriculture, and industry. However, new signs show that water concerns are increasing across the state, raising questions about long-term supply.

"We have one of the greatest water resources in the world, the Missouri River, running right through our state. And if we don’t think of ways to utilize it properly, the concern is that other states will figure out a way." – Shane Phillips, executive director of WEB Water.

Although the state is not facing an immediate crisis, warning signs are becoming clear. Some areas are limiting new water connections due to system capacity. Drought is lowering river and reservoir levels. Aquifers in certain regions are declining and not recharging quickly. In some cities, water use restrictions are already in place earlier than usual.

Leaders across the state are now focusing on future planning. Officials are working on large water projects that may cost billions of dollars. These projects aim to increase access to Missouri River water and expand regional water systems that deliver water through pipelines.

"Experts have shown us that we’re straining our aquifers in South Dakota, and we need to act now so our future generations don't have to react," said Kristen Conzet, director of the Western Dakota system.

Several major projects are in progress or under discussion. These include expanding existing systems like Lewis and Clark, improving WEB Water infrastructure, and planning large pipelines to serve more communities. Some of these projects may take decades to complete and require strong funding support.

The demand for water continues to grow due to population increases and long-term drought conditions. The state also needs to support agriculture, ethanol production, and future industries such as data centers.

Officials emphasize that planning must begin now because large projects take many years to complete. Early action will help protect water resources, support economic growth, and ensure reliable water for future generations.
