Workers delivered four Speece cones to the downriver Dissolved Oxygen Injection System site, Dec. 14, 2016.

The Speece cones, which are 22 feet tall, 12 feet in diameter at the base, and weigh more than 11 tons, force oxygen into river water and ensure current levels of dissolved oxygen are maintained before the shipping channel is deepened.

The system is scheduled to be operational by December 2017.

When complete, the dissolved oxygen injection system will employ 10 Speece cones – four downriver on Hutchinson Island, and six upriver near Plant McIntosh in Rincon – and process about 150 million gallons of water per day.
