A groundwater desalinisation plant is underway, aiming to diversify a city's water portfolio. The project's cost has increased to nearly $205 million, according to a recent estimate. This represents an increase of nearly 11% from previous estimates.

The cost increase is partly due to the potential addition of two to three waste injection wells. Test wells have been completed, tapping into the Gulf Coast Aquifer, and samples have been analyzed.

Further details on the project, including its progress and challenges, are available from the source. The increased cost and ongoing design of the waste injection wells are key aspects of the project's current status.
