Sustainable Treatments

As part of our commitment to delivering sustainable construction, BSG has successfully delivered the design, construction, and maintenance of sustainable treatment facilities such as ICW’s and Reed Beds.

These systems are based on providing highly efficient treatment using natural resources, such as emergent aquatic plants or reeds to treat effluent to the required consent standard. Other benefits of using these systems are low/no energy usage, increase biodiversity and improved overall water quality.
