What applying usually looks like

A general guide. Always confirm the exact steps on the official program page, since each provider runs its process a little differently.

1. 1

   Apply and get written approval first

   Submit your application to Boston Water and Sewer Commission and wait for written approval before you remove any turf or start work. Starting early is the most common reason a rebate is denied.

2. 2

   Do the conversion

   Replace your lawn with the qualifying landscaping, following the eligibility requirements above.

3. 3

   Submit your claim

   After the work is done, submit your claim on the official program page. Confirm the exact forms, receipts, and any photos they require there, since those vary by program.
