Mesa is using goats to rid one of its water reclamation sites of weeds and brush.

Under a six-month contract with the city's Utilities Department, Arizona Herdsman Eco Goats will provided 80 goats to clear the slopes of the water retention ponds at the Northwest Water Reclamation Plant.

The first 10 goats were brought into their new grazing area Jan. 5

Utilities Department Water Division Director Bill Haney says the design of the retention pounds and the amount of vegetation at the site make it difficult to use machines and to keep down the weeds.

Officials hope the goats can do a better job, saying in a statement they'll "eat just about anything resembling a plant."

Besides, Haney says goats are a "more sustainable and environmentally responsible form of weed control."
