Drinking Water Operator Certification
Contract Operator Guidelines

January 2004

Community and Nontransient Noncommunity
Public Water Supply System

Minnesota Statutes 115.71 - 115.77, and Minnesota Rules Chapter 9400, require that the person who has direct responsibility for the operation of a water system be properly certified. It is allowable to contract with a properly certified operator to meet this requirement provided the contract is submitted to the Minnesota Department of Health (MDH). In order to fulfill the certification requirement, the contract must specify the number of visits that the certified operator will make and the length of each visit. Because each facility is unique and has different management needs, it is difficult to establish set criteria. Although each situation will be reviewed individually, the following table presents recommended minimums. It is recommended that each visit be a minimum of two hours in length and at the following frequency:

Systems Classification Number of Visits
E 1/week
D 1/week
C 2/week
B 3/week
A 5/week

It is emphasized that these hours do NOT include the time needed to actually do facility operation and maintenance, only to direct those activities.  Turbidity and chlorine residual testing for surface water supplies and fluoride testing must be done on a daily basis by an operator (certified or non-certified).

In addition, the contract must include the following items:

  1. The certified operator's name and certificate number (and company name if appropriate);
  2. The period covered by the contract and provisions for renewal;
  3. The duties and responsibilities of the certified operator;
  4. The duties and responsibilities of the owner; and
  5. Provisions for notifying the MDH 30 days in advance of termination if the contract is terminated prior to the expiration date.

Please submit a copy of the contract to:
