Two friends. Two skillsets. One shared ambition.
Envirotech Drainage Solutions was founded by lifelong friends Callum and Barry, bringing together hands-on drainage expertise and a strong background in engineering, commercial management and health and safety.
A better way to deliver drainage work.
We set out to build a dependable, professional business where practical solutions, honest communication and doing the job properly come first.
From school friends to business partners.
Rooted in Bathgate.
Callum and Barry have been best friends since high school. Both from Bathgate in West Lothian, they had known each other for years before deciding to combine their different professional backgrounds and start Envirotech Drainage Solutions.
Barry had spent ten years working in drainage, building the practical knowledge needed to investigate problems and understand what happens on site. Callum brought an engineering and construction background, including commercial operations, health and safety, and experience working with public-sector organisations and private contractors.
That mix of experience became the foundation of a business built around good work, clear communication and lasting customer relationships.
Complementary experience. Shared standards.
Our different backgrounds help us look at drainage work from both sides: the technical challenges on site and the planning, reporting and safety expectations of the client.
Ten years in drainage.
Barry brings the hands-on industry experience behind Envirotech’s practical approach to surveys, investigation, clearance and drainage repairs.
His site experience helps shape the way we investigate problems, assess options and carry out the work.
Engineering, commercial and H&S.
Callum’s background covers engineering and construction, commercial responsibilities, project delivery and health and safety.
It includes experience working with public-sector organisations and private contractors, as well as office-based work for a leading engineering company.
We are both closely involved in the business and want our customers to feel the benefit of that personal accountability.
A practical approach, delivered professionally.
Our aim is not simply to attend a site and complete a job. We want clients to understand what we have found, what we have done and what we recommend next.
Clear investigation
Understand the drainage issue and select a proportionate way forward.
Professional delivery
Plan for the site, its risks and the people or operations around our work.
Evidence and communication
Provide useful updates, findings and records so clients can make informed decisions.
The experience behind our work.
From reactive drainage works to CCTV investigation, network mapping and infrastructure maintenance, our projects show the breadth of work we support throughout Scotland.
CSO cleaning & maintenance
Supporting combined sewer overflow infrastructure at sites across Scotland.
900 mm sewer CCTV survey
Large-diameter surface-water sewer condition surveying ahead of construction.
Warehouse drainage mapping
Drainage route and connectivity investigation to help document site infrastructure.
A challenge that went beyond drainage.
Envirotech began with a friendship that goes back to school. Away from site, we also like taking on challenges that bring people together and make a difference.
In September 2026, our Sewers to Summits Three Peaks charity challenge saw us carry a 24 kg manhole cover into the mountains in support of WaterAid and Forth Rivers Trust.
It’s a story about determination, teamwork and supporting causes that matter to us. You can read the full Sewers to Summits story in News & Insights.

Building a business for the long term.
We want to grow Envirotech into an established Scottish drainage contractor while staying true to the values we started with: technical competence, hard work, accountability and a personal service.
As our capability and team grow, we want clients to keep dealing with people who take pride in every project.
