Capacity Evaluation Forms

DNR has developed and is implementing a program to ensure that new water systems demonstrate capacity. The program, which became effective on September 1, 1999, consists of a capacity evaluation of proposed community and nontransient noncommunity water systems.

Forms were designed to help new other-than-municipal (OTM) and new non-transient noncommunity (NTNC) system owners provide the necessary information for the capacity evaluation. For this purpose, new OTM and new NTNC systems include systems which fall under this classification after an infrastructure expansion, change in type of population served (e.g. system will serve a school when it did not serve a school before), or increase in population served. A capacity evaluation does not need to be completed if the system was previously an OTM or NTNC system and will remain under the same OTM or NTNC classification after any system improvement, including constructing a new well on the system. Prior to construction, owners of new OTM and new NTNC systems must fill out, sign, and send the form to the DNR. Capacity evaluation forms may be downloaded by clicking on the link below:

• NTNC system owners must complete DNR Form 3300-246
• OTM system owners must complete DNR Form 3300-247

How to submit the capacity evaluation forms:

• Systems subject to DNR plan review: (NTNC pumping capacity greater than or equal to 70 gallons/minute and all OTM systems) The capacity evaluation is completed as part of the plan review process and uses information furnished in the water system plan. The appropriate capacity evaluation form should be submitted with the plan review information. Once the plan approval is granted and the capacity evaluation is reviewed, DNR will send an approval letter and capacity certification to the system owner.
• Systems NOT subject to DNR plan review: (NTNC pumping capacity less than 70 gallons/minute) A capacity evaluation must still be performed prior to system construction. Owners should send the completed capacity evaluation form (3300-246) to the Capacity Development Coordinator, Wisconsin DNR, DG/2, 101 S. Webster Street, Box 7921, Madison, WI 53707-7921. Once the capacity evaluation is reviewed by DNR, an approval letter with capacity certification will be sent to the system owner.
• If the information submitted on the evaluation form is incomplete, the form will be returned to the applicant, requesting the missing information within 30 days. Failure to return the completed form could result in enforcement action by the DNR.
