Clearvac

What Clearvac does

Clearvac is a UK-based private company specializing in marine wastewater management and air hygiene services for cruise ships, super yachts, and offshore oil and gas vessels. Founded in 2009 and headquartered in Sidmouth, Devon, the company delivers on-site field services through wholly-owned regional subsidiaries in the UK, Italy, Thailand, and Brazil, with demonstrated service reach into Norway, Poland, France, and the United States. Its core offering is a proprietary non-invasive black water (vacuum toilet) pipe descaling process that removes hard scale deposits and restores pipework without disrupting passenger or crew operations, backed by a 3-year guarantee; a complementary grey water service uses the proprietary Eco Drain-Away chemical, and a Sureflush Coupling addresses problematic vacuum toilet flushing. The company also delivers HVAC ductwork cleaning, ventilation hygiene compliance (including HTM03-01), and distributes AOP (Photohydroionization) air purification systems under a partnership with Pure Air Group, extending its footprint into land-based commercial facilities such as hospitals, schools, offices, and airports.

Revenue is generated primarily through professional service contracts and per-vessel service fees (quote-based, not publicly disclosed), with secondary streams from hardware and chemical product sales. Clearvac's go-to-market is enterprise field sales: service technicians travel to client vessels worldwide, supported by regional offices and a formal recommendation from EVAC Vacuum Systems, a major marine vacuum toilet OEM. The customer base includes Norwegian Cruise Line, Regent Seven Seas, Stena Drilling, and Subsea 7, alongside recurring engagements with multiple super yacht operators. The business model is asset-light but labor-intensive, dependent on the availability of trained technicians who can execute the proprietary cleaning procedures under operational constraints on board active vessels.

Scale indicators2 records

Recent moves6 records

Expansion highlights4 records

Emerging players

• Optimarin: Optimarin is a specialist in ballast water treatment systems for ships — a related but more productized niche versus Clearvac's service-led wastewater management. They serve overlapping vessel types and could expand into adjacent hygiene services.
• BIO-UV Group: BIO-UV Group designs UV-based water treatment and disinfection systems for marine and land-based applications. Their technology overlaps with Clearvac's chemical and equipment approach to marine wastewater and air hygiene, particularly in the yacht and cruise segment.

Broad incumbents

• Veolia Water Technologies: Veolia is a global environmental services and water treatment incumbent serving marine, offshore, and land-based commercial/industrial customers. Its scale and regulatory expertise make it a competitive threat across both Clearvac's marine and land-based segments.
• Alfa Laval Marine Service: Alfa Laval supplies heat transfer, separation, and fluid handling equipment to marine and offshore markets and runs a global service network. It addresses overlapping onboard wastewater and HVAC system needs for the same cruise and offshore customers.
• Wärtsilä Marine: Wärtsilä is a major marine technology and services provider with extensive ship lifecycle services, including environmental solutions. Its broad portfolio could subsume the type of marine hygiene and wastewater service niche Clearvac occupies.
• Wilhelmsen Ships Service: Wilhelmsen is a global maritime industry incumbent offering ship services, spare parts, and crew welfare products to the same cruise, offshore, and commercial shipping customers Clearvac serves. They are a much larger portfolio player that could easily enter niche hygiene services.

Others

• Pure Air Group: Pure Air Group is the manufacturer of the AOP (Photohydroionization) air purification systems that Clearvac distributes. As a partner/supplier rather than a competitor, it is an ecosystem participant with deep product overlap on Clearvac's HVAC/air purification line.

Direct peers

• Severn Trent Services: Severn Trent Services provides water and wastewater treatment solutions including marine and offshore applications, overlapping with Clearvac's wastewater management services. They also share the land-based healthcare/commercial building hygiene market.
• Cathelco: Cathelco is a UK-based specialist in marine water treatment, corrosion protection, and wastewater systems for ships, offshore platforms, and yachts — overlapping directly with Clearvac's black/grey water management offering for cruise, yacht, and offshore customers.
• Drew Marine: Drew Marine is a global supplier of marine chemicals, water treatment, and onboard services to shipping operators. It is a direct competitor to Clearvac in marine water/wastewater management and HVAC hygiene services across the same customer segments.
