CHATHAM CO., GA (WTOC) - As part of the Savannah Harbor Expansion project, the city is getting a new 17-acre reservoir to keep fresh water flowing when high tides push salt water into the Abercorn Creek water supply.
Here's how the $40 million reservoir will work. Normally, water is drawn from Abercorn Creek, treated and sent to your home. However, during super high tides, salt water can intrude into the fresh water and quality suffers.
The new reservoir will allow the utility to bypass the creek and draw fresh water from the reservoir until the tides go out, then switch back again.
Construction of the small reservoir will start next summer and take about a year and a half to complete.
