With the "GREEN" movement, the use of retention/detention, first flush technology and rainwater harvesting has become more widespread to reduce the environmental impact of development and population growth, especially in municipalities with finite water resources. LEED architects, engineers and builders have long recognized Highland Tank's protected steel water tanks for their strength, durability and functionality. With the addition of our new HighDRO®-Pure systems, we are continuing our commitment to protect the environment and conserve our precious natural resources to benefit our world today and tomorrow.
