After three decades as the UK’s leading aquatic science consultancy, APEM recently passed the milestone of working for all 11 water and wastewater companies in England, Scotland and Wales.

Projects involve every one of APEM’s specialist teams and range from consultancy and laboratory analysis to fieldwork and aerial surveys, and across freshwater, marine and coastal habitats.

The 11 water and wastewater companies in Great Britain are Anglian Water, Dwr Cymru Welsh Water, Northumbrian Water, Scottish Water, Severn Trent Water, South West Water, Southern Water, Thames Water, United Utilities, Wessex Water and Yorkshire Water.

Among APEM’s longest standing clients are United Utilities, South West Water, Severn Trent Water and Dwr Cymru Welsh Water. Among the newest are Scottish Water and Anglian Water.

APEM’s managing director, Dr Keith Hendry, said: “This is a major milestone for us, especially coming at a time when we’re celebrating 30 years in business.

“As well as carrying out individual projects for water utilities we have also aimed to secure places on supplier frameworks. I’m delighted to say that we are now on frameworks with seven water companies covering a wide variety of services from laboratory work to aerial surveys.”

Thirty years ago, APEM’s very first piece of work was with United Utilities. Since then the two companies have worked together almost continuously, with United Utilities becoming one of APEM’s most important clients.

Recent work for Scottish Water includes the eradication of invasive signal crayfish from Dalbeattie reservoir by our field team, while on-going work in Wales includes the largest programme of scientific coastal investigations ever undertaken by Dwr Cymru Welsh Water.

After many years of working together, Severn Trent Water last year appointed APEM to its AMP6 Water Resources Planning framework agreement, covering specialisms such as environmental monitoring, hydroecology, flow gauging, groundwater modelling and abstraction licence support.

Our specialist laboratories provide sampling and analysis for many water companies, as well as all the relevant environmental regulators in the UK.

Working for Northumbrian Water our laboratory scientists provided analysis of brackish water samples and data on phytoplankton communities, as well as reports on toxic and nuisance phytoplankton species.

Among our work for Thames Water in recent years are our catchment-wide walkover surveys to identify sources of diffuse pollution. The surveys aimed in particular to identify sources of priority substances causing onerous treatment costs upon abstraction. Altogether APEM’s field team has carried out walkover surveys along over 15,000 km of rivers throughout the UK and continues to develop an innovative partnership with the APEM remote sensing team.

Among our upcoming projects with Southern Water will be electro-fishing surveys, walkover surveys and flow gauging as part of an ambitious scheme to restore more natural flow regimes to the River Bewl.

With the requirements of the 2009 Eels Regulations as a key specialism, helping water companies to protect this severely threatened species is an important part of APEM’s work. Most recently, APEM was commissioned to carry out an eels regulations assessment on behalf of Wessex Water. Eels regulations and eel screening work has also been carried out for Yorkshire Water and Anglian Water, among others.

Meanwhile APEM’s aerial survey pilots and image analysts have recently been searching for misconnected wastewater pipes for Anglian Water and United Utilities.

APEM’s aerial surveys have also searched for unregistered animal drinking troughs for South West Water, as well as deploying thermal imaging cameras to locate the diffuser heads of long sea outfalls for Dwr Cymru Welsh Water, United Utilities and South West Water.

Over the last 30 years APEM has steadily opened new offices around the country and now counts four offices in England, three in Wales and one in Scotland, as well as offices in Germany and the US.
