Our knowledge, coupled with years of experience, provide water treatment solutions that are custom to specific problems in an eco-conscious way.



  • Harvesting the second largest natural resource on Planet Earth provides a 100%
    non-toxic approach to water and wastewater treatment.

  • Converting a waste to a resource

  • Because these proven solutions are less complex, they can be cost-effective




We bring over three decades of field experience, chemical engineering, geology, construction and manufacturing to each solution on projects we undertake. Whether it’s solutions for a new system or retrofit for an existing one, all projects are executed by professional engineers and geologists. PE, PG, QSD, CEG certified.


All manufacturing is partnered with fully-certified partners and chemical blenders. Engineered systems are manufactured either skid mounted or containerized, mobile or stationary in 100,000 square foot manufacturing facilities. ISO 9001, UL 508, CE, ETL, UL 698 Certified. Full mechanical, electrical, chemical, pneumatic and integration into independent and existing SCADA control systems.
