An army of engineers as well as innovative technology have been hard at work trying to improve river health in Warwickshire.

Severn Trent has set out a £450 million plan to deliver more than 900 enhancements to improve overflows in the Midlands.

In three months, the company says it has completed more than 55 projects benefiting the county's rivers.

These include installing storage solutions and introducing cutting-edge innovations like nature-based solutions in reedbeds and SAF (Submerged Aerated Filters) units.

Neerja Upadhyay, Severn Trent’s head of river health, said: "Our ambition is to have the lowest level of spills in the industry.

"This is a challenging programme given the scale and ambitious timeline, but we’re making progress and we quite literally have an army of engineers working to make sure that we cut spills and improve the local health of the rivers our customers know and love."

One of the standout projects is the installation of SAF units at the water company's Frankton wastewater treatment works in Warwickshire.

Holly Thomson, assistant project manager at the company, said: "SAFs are game changers.

"They use natural biological processes to clean wastewater and can be set up in no time.

"It allows us to treat more wastewater, faster.

"It’s a huge win for Warwickshire and supports the wider work the region is benefiting from – all the projects and improvements we’re making will help us to dramatically reduce our impact on local rivers."

The company has also installed reedbeds, which help to naturally filter and clean wastewater, improving river health.

Severn Trent has invested £78 million in bringing parts of the River Leam up to bathing quality standards using ozone technology and a further £35 million to remove harmful phosphates at the Finham treatment works.

The company has a storm overflow action plan ready to bring £300 million of investment into Warwickshire by 2050.
