How BioMarsh Environmental’s humble beginnings spurred a 250-vehicle fleet serving UK blue-chip companies and water authorities nationwide
Built on responsiveness and practical problem-solving, BioMarsh Environmental has grown over more than five decades from a family farm operation into a nationwide specialist in environmental logistics. What began with a single tanker supporting a pig farm has evolved into a 250-vehicle fleet delivering time-critical services to water authorities, construction sites and utilities across the UK.
Established by Rod and Margaret Travers at their Waltham Abbey farm in the 1970s, the company’s origins remain central to how it operates today. The first septic tank, bought to support the piggery and streamline local waste removal, laid the foundation for a business built around solving immediate, real-world problems.

Managing Director Brian Driver highlights that the founding family remains actively involved, with multiple generations contributing to day-to-day operations. “Essentially, BioMarsh was born from Rod Travers purchasing a tanker for his pig farm, which led to the national operation we’re running now,” he says.
“Originally our work mainly comprised domestic septic tank services, but we now operate over 250 vehicles across the UK. Primarily we support water authorities with over-pumping and pollution prevention works, and we partner with most of the major water utility companies to deliver flood risk mitigation within communities.”
Scaling services for water authorities and beyond
BioMarsh carries out sewer jetting and technical services including drain and sewer inspections for both water authorities and domestic customers. The company has expanded into full turnkey solutions, offering patch lining, drain rehabilitation, septic tank installation and civils plant work.
Much of this work is time-sensitive and often reactive. Over-pumping and pollution prevention jobs frequently require rapid mobilization to prevent service disruption or environmental incidents, placing a premium on coordination and fleet availability.
“We transport clean water deliveries to site for non-potable activities such as hand washing and toilet facilities, and we remove sewage from the tanks underneath temporary accommodation blocks on construction sites,” explains Brian.
In recent years BioMarsh has also extended its expertise into the utilities, civils, hospitality and fast-moving consumer goods sectors.
Securing Tier 1 status on AMP8
BioMarsh’s long-term relationship with Anglian Water, spanning nearly 20 years, helped it secure preferred Tier 1 supplier status on the new AMP8 framework. “Our Tier 1 status on the AMP8 framework has been built on a relationship of trust,” reflects Brian. “Although we’re competitive on pricing, we have a strong structure with excellent supervision, competent drivers, solid training, and real confidence from the client in our vehicles, operators, supervision and management team.”

That trust is particularly important in a sector where work is often reactive and high-stakes, requiring suppliers to respond quickly and operate reliably under pressure.
Digital transformation driving efficiency
Targeted investment in equipment and technology has delivered 40 percent growth in turnover. The introduction of a mobile workforce platform has been particularly significant. “With this platform the team can carry out much of their work in the field digitally,” says Brian. “We can provide real-time feedback once engineers close jobs on site, giving the customer instant visibility of what is required next and any follow-on works that may be needed.”
For a business coordinating hundreds of vehicles across geographically dispersed, time-critical jobs, real-time visibility has become operationally essential. The platform simplifies task distribution between drivers and integrates via open APIs with the company’s other systems, enabling live job tracking, visibility of driver availability and more efficient national fleet planning.
People, culture and safety at the core
Stability within the management team is a major strength, with many senior managers having been with BioMarsh for more than 20 years. “There is a real nucleus there,” notes Brian. “Our health and safety team has been driving integral practices within the business, helping to raise competency levels both in the field and in office roles. Developing existing staff and offering new opportunities has been key to our success.”
Operational consistency is reinforced through structured training and supervision. The introduction of an in-house driver trainer and rigorous supervisor-led assessments has raised standards, resulting in reduced accident frequency, fewer customer complaints and fewer fleet incidents.
Driving sustainability across the fleet
BioMarsh is continuing to reduce the amount of carbon it uses, with the compliance team actively targeting further improvements in 2026. “We’ve implemented a system that gives us more visibility of our work across the country, and where the vehicles are operating, meaning we can conduct smarter planning in terms of fleet deployment,” Brian reveals. “This allows us to improve efficiency and reduce unnecessary mileage, supporting both carbon reduction and operational performance.”
The company has also transitioned company cars to electric vehicles across managerial and sales teams, alongside supporting tree planting initiatives through its work with Forest Carbon and progressing towards EcoVadis accreditation.
2026 and beyond
Further priorities for the year ahead include growth through tender opportunities, with 30 presently active at different stages. “We’re also making structural changes in order to deliver work more regionally and manage people in-area, supported by local depot networks,” Brian concludes. “One of those areas is Swindon. We’re also looking at depots in Bury St Edmunds and Lincoln. The depot in Barnsley is already operating; however, we are focusing on scaling that up too.”
This regionalization reflects a broader focus on improving response times and operational efficiency by positioning resources closer to where work is carried out. The acquisition of SewerSurveys UK in February 2026 further strengthens BioMarsh’s capabilities in CCTV sewer surveys, diagnostics, mapping and technical reporting.
