Is Your Treatment Plant Ready for the Year 2,000?

The "Millennium Bug" Could Cause Problems With Monitoring, Operations, Communications, Laboratory Analysis, and Reporting

The Year 2000 computer problem could adversely impact the state's wastewater treatment plants if it is not addressed. How? Many treatment plants use equipment containing embedded computer chips and control systems that may be unable to interpret the correct date.

Background

The Year 2000 problem started years ago when early computers had limited memory and storage space. Programmers saved space by storing the minimum amount of data necessary for computer functions. In this case, they saved space by designating the date with two digits (e.g., 1954 = 54, 1970 = 70, etc.)

Recording dates with two digits works fine until the century changes. As the next century approaches, some computers may not interpret the year 2000 as being greater than 1999 and may consider it 1900.

Embedded Chips

Wastewater treatment facilities utilize automated environmental emissions monitoring and control systems that contain embedded controls. Embedded controls, which may have the Year 2000 problem, are often physically inaccessible making them difficult to fix or replace.

Embedded systems that operate continuously may present what appears to be an equipment malfunction on or about January 1, 2000. It is impossible to determine prior to the event whether the malfunction will occur. Embedded systems not in continuous use may fail to start or to operate correctly when they are first switched on in the Year 2000. Even when the application itself is date and time independent, the hardware/operating system platform on which it is based may not have this independence and may not be Year 2000 compliant.

While it is the responsibility of wastewater treatment plant owners to ensure proper operation, the EPA wants to increase awareness, encourage necessary action, and offer support. They have compiled the following list of web information sources to help treatment plant owners and operators address the Year 2000 problem:
