Protecting the Environment

How We Use Advanced Technology

Our state-certified professional operators prevent spills and leaks using modern maintenance and management tools and advanced technologies. Our goal is always to protect public health and the environment.

  • Regular video inspection of pipelines to ensure that they are secure and leak free.
  • Special vacuum and water jet trucks to clean the pipelines.
  • Computer systems and mathematical modeling to design, operate, and maintain facilities.
  • Use of a computer-based SCADA (Supervisory Control and Data Acquisition) system to continuously monitor pump stations and treatment processes in order to immediately spot trouble, such as loss of power or equipment malfunction.
  • Use of a geographical information system (GIS) to provide quick and easy archiving and access to information about system maintenance, service calls, emergency repairs, and new development.
  • Over 400 discharge water sample measurements are taken each month. We collect and analyze samples for metals, pesticides, solvents and other constituents known to be harmful to the quality of our receiving water, land and air.
