Staffordshire and Cheshire's Fire and Rescue Services are supporting a major incident in Derbyshire - where a reservoir dam is at risk of collapse.
There has been extensive damage to the structure at Toddbrook reservoir, which could lead to flooding of nearby homes.
The reservoir contains 1.3million tonnes of water, and the dam holding it contains 300 million gallons.
Staffordshire is supplying one of ten High Volume Pumps deployed overnight to assist in reducing water levels.
Just a day after declaring a major incident after flooding in Cheshire, the county's Fire and Rescue Service have sent a HVP Tactical Advisor to support efforts.
The HVPs have the capacity to move up to 7,000 litres of water per minute.
They are pumping water from the reservoir to other locations to reduce the pressure on the reservoir wall, in an attempt to reduce the impact on the local community.
It is currently anticipated that the incident will run for at least 2 to 3 days.
The Staffordshire Enhanced Logistics Support Team has also been at the site.
