Ms. Lawhead-Duncan:
Bicknell Water Department is classified as a DSL water distribution system. Mr. Horst is certified as a grade DSM water works operator and, therefore, cannot be the certified operator in responsible charge of your system. Mr. Horst does qualify to apply to sit for a DSL examination, however. The next scheduled examination will be May 4, 2006, with an application deadline of March 20, 2006.
During a recent conversation with someone from the Bicknell Water Department it was mentioned that Mr. Dearing holds a grade DSL water works operator certification. We do not have written documentation that Mr. Dearing is the certified operator in responsible charge. It is the responsibility of the governing body of a public water system to designate an appropriately certified operator to be the operator in responsible charge. If Mr. Dearing is not to be considered the certified operator in responsible charge of Bicknell Water Department, please provide us with the name of the operator you have designated who holds the appropriate certifications.
The descriptions of a class DSM and DSL public water systems are as follows:
A class DSM (Distribution System Medium) includes systems that serve a population greater than or equal to 3,301 but less than or equal to 10,000 people and have no mechanical means of movement of water other than pressure tanks or storage tanks, or consist of pump, storage tanks; booster pumps to storage tanks.
A class DSL (Distribution System Large) includes systems that serve a population greater than or equal to 10,001 people; or consist of the following: storage tanks, booster pumps to the distribution system, or mechanical devices for movement of water beyond storage.
The operator’s role in distribution is as follows:
- Operate the system to maintain water quality by managing water age in the system, maintaining positive pressure at all times, and controlling water direction and velocity.
- Maintain pipes, valves, pumps, and other facilities to ensure a continued flow of potable water.
- Monitor and operate valves and pumps to vary the amount of water supplied as the demand varies.
- Install connections to supply water to new customers.
- Maintain main line and customer water meters.
- Read customer water meters.
- Sample water to ensure that its quality is maintained.
- Operate a cross-connection control program to ensure that nonpotable liquid does not flow into the potable system.
- Maintain system maps and records;
- Keep informed on new technology and investigate the use of better equipment or methods of operation that could improve the efficiency or safety of distribution system operations; and
- Recommend to superiors any repairs, replacements, or improvements that should be made to the distribution system.
- Set up emergency procedure in case of contamination or system failure; e.g., power outage or equipment failure
- Meet with IDEM field representatives.
