GF continues to combat zebra mussels

The growing Zebra mussel population in the Red River will cost the City of Grand Forks another $332,000 dollars.

The mussels were first detected in the river system in 2015 – and have been growing ever since. The microscopic larvae attach to rocks, docks, boats, bridges and pipes. The accumulation of mussels can damage underwater infrastructure.

Since 2020 the city has utilized a chemical feed system to help eradicate zebra mussels on the suction side of the water intake pipes. The latest project involves construction of a more permanent feed system and containment area.

Water Works Director Melanie Parvey says 100% of the chemical is removed through the treatment process.  “The goal is to get the water to the plant so we can treat it.”

The city inspects the intake screens on an annual basis and has detected the invasive species. The bid package was approved by the city council last week.
