US City Considers Wastewater Plant Upgrades

The US city of Yakima is considering two upgrades to its wastewater plant.

The projects, which could cost $60m in total, would improve the water quality of the Yakima River.

One of the projects would reduce the levels of phosphates in water to meet US clean water standards.

Pharmer Engineering has been awarded the contract to design a reactor to capture the chemical, which is found in detergents and dishwashing soaps.

The reactor would also produce fertilisers that could be sold to contribute to its operating costs.

The second project will look at how water is discharged from the treatment plant when the Yakima river channel is eventually altered, according to yakima-herald.com.
