RUKHYDRO Clients

Examples of RUKHYDRO Limited clients supported since November 2009 are listed below:

Client Period Scope
Anglian Water Jan 2019 to Jun 2019 Reviewed the likely impacts of climate change on nitrates in groundwater in Anglian Water public water supply abstractions. The work included setting the scene of the Anglian region to focus the investigation, a literature review of national guidance on climate change impacts (RIDE forum) and work by BGS and others since 2011, and revisiting the basic principles leading to nitrate variation in groundwater. Possible effects and an estimate of their magnitude were summarised and a strategy was recommended for Anglian Water to consider for AMP7. Work direct.
Groundwater Science Ltd Aug 2018 Developed historic nitrate leaching trends as inputs to a Groundwater Science flow and transport model prepared for a bottled water client. The model helped explore the influence of different abstraction scenarios on water quality.
