Rapid City evaluates water infrastructure for potential data center demand

Rapid City officials are exploring the long-term potential of piping Missouri River water to the Black Hills, as discussed in the recent Legal & Finance Committee meeting. While the city’s current water rights are deemed sufficient through 2115, the committee acknowledged the importance of monitoring the Missouri River water project as it develops.

The conversation highlighted the growing demand for water, particularly with the potential arrival of a data center in Rapid City, which could significantly increase local water usage. Experts noted that data centers typically require substantial water for cooling, and if they opt for more efficient cooling technologies, it could lead to higher electricity consumption instead. This shift raises concerns about the city’s infrastructure, as existing water mains may not support the high demand from such developments.

The committee emphasized the need for careful evaluation of the water supply system, particularly in commercial areas where demand could exceed current capacities. Upgrading water mains from 8 inches to larger sizes may be necessary to accommodate future growth and ensure reliable service.

As Rapid City considers its water supply strategy, the implications of these discussions will be crucial for planning and infrastructure development in the years to come. The city remains committed to assessing both current needs and future demands as it navigates these challenges.
