In many, many locations in the U.S., local utilities and state and local government agencies have joined together to offer rebate programs for products and installations that will reduce energy and water consumption by business and industry, as well as by residential users.
Under many of these programs, any measure that will reduce consumption qualifies, although not in every state or locality. There are programs under which TWT Deposit Control Systems have qualified for such rebates. If you are considering installations in locations where conservation is encouraged or required, you may wish to enquire with your local utility or appropriate state agency to see if they offer financial support for such efforts.
