PROJECT EXPERIENCE
A compliant upgrade, ready for the future
At this large detached property in Arundel, the existing septic tank no longer met current Environment Agency requirements and needed to be replaced.

WHY WES?
Specialist experience, applied to the whole project
Led by Mark Ward, WES combines decades of practical off-mains drainage experience with a clear understanding of system design, compliance and on-site delivery.
From an initial assessment through to installation and commissioning, clients have one knowledgeable team responsible for identifying the right solution and seeing it through properly.
Independent, site-specific advice
Recommendations are shaped by the property, the site and the requirement—not by a predetermined product.
Compliance considered from the outset
Design, regulation, approvals and documentation are addressed early, reducing the risk of problems emerging later.
Experienced project delivery
WES can coordinate the complete process, providing one knowledgeable point of responsibility from assessment to handover.
“Mark managed the whole project from start to finish of the installation and I would have no hesitation in recommending WES Ltd to anyone, it’s so important to get a professional company who know the rules and regulations to ensure you are fully compliant.”
