The New Jersey Water Bank (NJWB) is a partnership between the New Jersey Department of Environmental Protection (NJDEP) and the New Jersey Infrastructure Bank (I-Bank) to provide low cost financing for the design, construction, and implementation of projects that help protect and improve water quality and help ensure safe and adequate drinking water.

The NJWB finances projects by utilizing two funding sources. The Trust issues revenue bonds which are used in combination with zero percent interest funds to provide very low interest loans for water infrastructure improvements. The NJDEP administers a combination of Federal State Revolving Fund (SRF) capitalization grants, as well as the State's matching funds, loan repayments, State appropriations and interest earned on such funds.

WISE Calculator- Financing Cost Estimate:

The WISE Calculator compares the cost for financing environmental infrastructure projects through an independent bond issuance versus the Water Bank.
