Link to a White Paper on the subject:
"There is good news for commercial, industrial, and institutional water users looking to treat and reuse water onsite as a means of increasing the reliability of water supplies and achieving sustainability goals. A new law went into effect on October 1, 2014 allowing private sector companies to obtain Clean Water State Revolving Fund (CWSRF) loans to construct onsite industrial water reuse projects for the first time.
The 2014 Water Resources Reform and Development Act (WRRDA) was signed into law on June 10, 2014 with the goal of helping to modernize the nation’s water infrastructure. WRRDA also allows privately owned water reuse facilities to have access to government subsidized loans for the first time. While public water utilities have long had access to government subsidized financing through the CWSRF, industries have had to finance their industrial water treatment and reuse systems primarily through a combination of commercial loans and the issuance of corporate bonds.
The WateReuse Association has released a new White Paper that explains the changes in eligibility for the CWSRF, the pros and cons of this financing option, and the steps to take to apply for funding."
