Stakeholder - ALS Environmental

Yorkshire Water

Yorkshire Water supplies water and sewerage services to 4.7 million people and 130,000 businesses in the Yorkshire region.

Yorkshire Water

Yorkshire Water is one of Yorkshire’s largest businesses. The Company supplies around 1.24Bn litres of drinking water each day. This involves collecting, treating and distributing clean drinking water, as well as collecting, treating and disposing of around 1Bn litres of treated waste water back into the environment.

Ensuring clean, safe drinking water for customers requires rigorous testing. Yorkshire Water has employed ALS Environmental as their analytical services partner since 2010.

These include:

  • Microbiology
  • Cryptosporidium
  • Inorganic Chemistry
  • Organic Chemistry
  • Ecotox

Key Account Management

A dedicated key account manager provides full time support to the analytical contract. This allows ALS Environmental to keep Yorkshire Water abreast of any developing situations that may be of special interest. The key account manager provides KPI data to both parties and is in place to deliver the seamless running of a major utility contract.

Sample Collections

ALS Environmental provide a refrigerated collection service for all clients, including the Yorkshire Water project. All of their vans are tracked, traced and monitored to allow ALS staff to advise on approximate sample collection times and collection conditions. The monitoring of the temperature provides an extra re-assurance that the samples have been analysed within the “Guidance on Deviating Samples” directive laid down by the European Union.

We had potential water quality problem due to the actions of a third party and needed samples taken as a matter of urgency. Although this was outside the strict terms of our contract with ALS they were able to provide a sampler on a Friday afternoon, get the samples taken and returned to their labs for analysis.

They backed this excellent performance up by emailing us the sample results over the weekend. All in all a great piece of customer service!

    What is a Stakeholder?

    A stakeholder is a Mircosite that has the power to highlight a product or service, launch a promotion, or promote brand awareness to the construction industry in a way that full websites or more traditional marketing cannot.

UK Construction Online is updated daily, with the latest news across all sectors within the construction industry and all stakeholders are promoted on both social media and to a mailing list of over 122,000 subscribers.
