Beginning October 1, 2015, all Publicly Owned Treatment Works (POTW) projects receiving assistance through Iowa’s Clean Water State Revolving Fund (CWSRF) must comply with a new requirement addressing cost and effectiveness. This new requirement is found in Section 602(b)(13) of the Water Resources Reform and Development Act of 2014 (WRRDA), which amended the Clean Water Act.
CWSRF programs may either require submission of a cost and effectiveness analysis or allow applicants and their consulting Professional Engineers to self-certify that they have conducted such an analysis. Iowa’s CWSRF has chosen to accept self-certifications and will not review the analyses.
Click here for the self-certification form. It requires an authorized signature from the Applicant for assistance and a certification from the consulting Professional Engineer.  The signed and sealed form should be submitted with the final plans and specifications.
Iowa’s CWSRF has not developed specific criteria or guidance for the analysis of cost and effectiveness. For more information on how to conduct such an analysis and to select projects or activities that maximize the potential for water and energy conservation, Iowa’s CWSRF recommends the following resources:
