We Purify Everything
Today, LZT is a global group uniting 9 companies across 2 continents and more than 6 countries — primarily Spain, Iceland, Mexico, Costa Rica, Latvia, and Lithuania.
What unites the Group — and where it all started — is our passion for clean water technologies. The name LZT was born in 2008 when we launched residential wastewater treatment solution companies in Lithuania and Latvia, alongside our industrial wastewater treatment plant company.
Ever since then, we purify everything.





















We Purify Wastewater
We work with commercial, residential, and public-sector clients to deliver efficient and sustainable wastewater treatment solutions
Our systems are customized to meet the diverse requirements of everything from private residences to large-scale industrial facilities.
Through synergistic icollaboration, each company excels in its own field.
We Purify Processes
Agility, mobility, and a can-do attitude fuelled our transformation from a small local wastewater treatment innovator into a global enterprise.
As LZT Group evolved into a highly diversified international organization, we’ve remained firmly opposed to bureaucratic inertia and process-driven culture.
Instead, we focus on delivering practical, results-oriented solutions worldwide.
We simplify and optimize every stage of collaboration—from production and implementation to service—making processes leaner, faster, and more effective
We Purify Sustainability
In a world where sustainability is too often used as a slogan, we are committed to functional sustainability — solutions aligned with real human needs.
This means designing systems that not only meet environmental standards, but also perform reliably in diverse climates, communities, and economies.
We believe a truly sustainable future is built by integrating green technologies seamlessly into everyday life.
