Design & Construction of Drinking Water Treatment Plants
Lithuania is unique in Europe, with 95% of its drinking water sourced from underground reserves. Our expertise ensures efficient treatment solutions tailored to deep groundwater extraction.
We develop, construct, and modernize:
- Underground drinking water treatment plants (pressure and gravity-based systems)
- Surface water treatment plants
- Industrial water treatment plants
Surface Water Treatment Plants
Surface water requires multi-stage treatment to remove sediments, organic matter, and contaminants. We design cost-effective solutions ensuring safe and clean drinking water supply for municipalities and industries.
- Treatment solutions for lakes, rivers, and reservoirs
- Coagulation, sedimentation, and filtration processes
- Disinfection technologies to meet drinking water standards
Industrial Water Treatment Plants
Industrial water treatment requires tailored solutions to meet specific process requirements and environmental regulations. We develop systems that ensure both efficiency and compliance.
- Custom water treatment solutions for industrial applications
- Process water purification for manufacturing, food production, and energy sectors
- Minimizing environmental impact and optimizing resource efficiency
Underground Drinking Water Treatment Plants
Lithuania’s underground water lies at depths of 35m or more, naturally protected from surface contamination. Our systems ensure optimal extraction and treatment while preserving water purity.
- Pressure filtration systems for high-efficiency water purification
- Gravity-based treatment plants for cost-effective, large-scale operations
- Advanced filtration technologies to remove iron, manganese, and organic matter
Underground Water Treatment: Pressure vs. Gravity Systems
Lithuania’s drinking water comes 95% from underground sources, requiring specialized filtration and treatment to meet quality standards.
Ideal for deep groundwater sources, this system removes iron, manganese, and organic matter efficiently.
Designed for high-capacity plants, gravity filtration optimizes operational costs while ensuring consistent water purity.
