ISO 14001 Certification

Protecting and improving the environment—particularly our water resources—is an important part of our mission.

In order to effectively manage the impact of our services on the environment, Charleston Water System has subscribed to a voluntary standard created by the International Organization for Standardization, or ISO.

ISO was founded after World War II to standardize equipment, manufacturing, and construction practices. Since then, ISO has grown to include more than 16,500 different standards for everything from quality control to environmental management, and 138 nations have adopted these standards.

About ISO 14001

In 1999, Charleston Water System became the first public water or wastewater utility in the nation to become certified under the ISO 14001 standard for environmental management. This certification requires the implementation of an Environmental Management System, or EMS, which is a set of standards that provide a framework for how to identify and control environmental impacts, both positive and negative.


Our Environmental Management System provides a framework for managing everything from standard operating procedures to record-keeping. 

There are many reasons why an organization should take a strategic approach to improving its environmental performance.  Implementation of the ISO 14001 standard helps:

  • Prevent pollution and improves the environment.
  • Demonstrates compliance with current and future statutory and regulatory requirements.
  • Minimizes operations that adversely affect the environment.
  • Increases cost effectiveness and competitiveness.
  • Promotes technological advances.
  • Affirms our commitment to environmental protection to our stakeholders.
Charleston Water System's commitment to ISO 14001 ensures that our customers receive safe and reliable water and sewer services. The focus of ISO 14001 is to ensure that all processes related to the environment are identified, managed, and reviewed on a routine basis.
