Who wants them and who gets them?
I've talked to many potential clients, friends and family who would love to have a "water feature" in their landscape. However, a huge majority of them come up with the usual reasons why they can't have one:
-- too hard to take care of
-- not enough time to keep it running correctly
-- too expensive

What makes them great?
-- Pondless systems can fit into much smaller areas than traditional water features
-- They can be installed in a much quicker time frame
-- More potential profit
-- Easier maintenance for homeowners and less liability
-- Neighborhood bird bath. The female chickadees will thank you.

Your two cents
