From our history of onshore thermal and membrane desalination Veolia Water Technologies VWS Westgarth moved offshore in 1992 providing the first commercial installation of sulphate reduction membrane technology on the then AGIP Tiffany platform.

Our quality management system is at the core of our business and aims to develop consistent working practices which assist with the minimisation of our business risks.

The evolving quality management system focuses our efforts within all key areas of the business through continuous development of our processes to meet both internal and external customers requirements.  These improvements help us utilise our resources and skills by maximising productivity and effectiveness and thereby keeping overheads at a minimum.

From 17 January 2018, we demonstrate our commitment and effectiveness to customers through the implementation of the international standard "ISO 9001:2015 - Quality Management Systems - Requirements" which  replaced the ISO 9001:2008 version of the standard. 

We are certified in accordance with the full requirements of ISO 9001:2015 through nominated certifying body, LQRA (Lloyds Register Quality Assurance Ltd).  LRQA were the first certifying body to be awarded the UKAS accreditation mark for assessment of quality management systems to ISO 9001 (plus many other international standards) and are internationally recognised as a certifying body that set high standards of achievement.

Quality assurance activities are monitored and measured for effectiveness through performing internal audits against our quality management system procedures and processes.


Health, Safety and Environment

We are committed to ensuring the Health & Safety of all employees involved in all elements of our operations. 

We are proud of the fact that we can demonstrate an excellent safety record in all aspects of the business. People are trained to the highest standards and their responsible attitude ensures that we maintain our impressive record.

Working as a team, promoting and taking pride in our own safety culture in the design of our work implementations in every facility where we operate and throughout any support services we provide on our Clients sites onshore and offshore.

We acknowledge and support the high level of emphasis placed by the customer on these aspects of its business. In this respect we will ensure that such HSE conditions are passed on to its suppliers and in particular, to its main fabrication subcontractor(s) for application in their construction operations.

 As well as complying with contractual Health, Safety & Environmental requirements and appropriate statutory and regulatory obligations, we always ensure Health, Safety & Environmental issues have a high profile during all phases of a project. 

Attention to Health, Safety & Environmental aspects is perhaps most important during construction and commissioning works and in these operations, our Construction Department has developed comprehensive Site Health & Safety and Site Operations Manuals (00000-GM-00001), which are rigorously implemented at fabrications/construction facilities operated by us.  We audit fabrication/construction subcontractor’s own Health and Safety Systems to ensure that adequate standards are in place.

HS&E aspects are also actively considered in all other project related activities, including everyday Head Office activities.  The objective is to provide the customer with a plant that is safe to operate and maintain with the minimum effect on the environment.

Consideration of HS&E aspects starts at the initial Sales, Marketing and Tendering phase of a project and continues throughout the project execution phase, in the development of the project execution strategy and planning of all project activities including design, engineering, procurement and construction.

In particular, during the design/engineering phase of the project we implement a series of formal design reviews (e.g. hazardous area classification, safety and risk assessments) which are a mandatory requirement of the our Quality Management System for every project.  Each of these internal reviews considers Health, Safety & Environmental issues under headings that include:

·                Safety and environmental compatibility

·                Compliance with regulatory requirements

·                Constructability and ease of assembly

·                User instructions and Health and Safety information

·                Avoidance of foreseeable risks to persons carrying out construction,                                commissioning and operation or cleaning works.

·                Material handling, operability and access/egress.



At VWS Westgarth Ltd, we maintain the highest standards through our people. We have extensive experience in our work and couple this with a culture that ensures collaboration, innovation and drive to perform
