News Briefs: Ancient Water Treatment System Uncovered in Guatamalan Forests

Also in this week's water and wastewater news, utility crews in Nashville are examining underground infrastructure in the aftermath of the Christmas Day bombing on Second Avenue

The oldest known example of a water treatment system was recently uncovered in the tropical forests of Guatemala.

The ancient Mayan city of Tikal was built more than 2,000 years ago and was using zeolite to filter out harmful microorganisms and toxins, according to recent research published in Scientific Reports.

Researchers collected sediment core samples from drinking water reservoirs used by the ancient city, and mineral analysis revealed the presence of zeolite, which is used in purification processes for its unique porous properties.

Major Sewer Line Failure Stops Shellfish Harvest in a Virginia City

Officials have placed a ban on shellfish harvesting after a major wastewater line broke in Newport News, Virginia.

The 36-inch line break caused wastewater to pour into the streets, making travel difficult in the area.

Hampton Roads Sanitation District General Manager Ted Henefin tells WAVY News it’s a significant issue. “Pretty confident it’s a major failure. It’s coming out of the ground at that point and basically running through the storm drain and into the local bodies of water.”

He says crews will have to perform controlled releases upstream in order to repair the broken pipe.

Nashville Utility Workers Examine Underground Infrastructure After Bombing

As a result of the recent Christmas Day bombing incident in Nashville, Tennessee, utility crews are inspecting and cleaning sewer lines to determine the extent of the damage in the Second Avenue area. The cost of the endeavor is about $75,000.

Some of the area’s clay pipes date back to 1903, according to officials, and there’s concern the blast could have damaged that underground infrastructure.

“When you have an older clay pipe especially, that type of vibration could have caused it to fail,” Sonia Allman, Metro Water Services’ Public Information Officer, tells WTVF News.
