Management Approach

Water is one of the key components in our production of asphalt emulsion. To ensure adequate water supply, all manufacturing facilities contain a surface water reservoir to decrease dependency on public water supply. Water drainage systems in the plants are designed so that water and any runoff waste is captured by the system so that we may reduce, reuse, and recycle for our internal use. This prevents public water contamination and shortage of water supply during droughts.
