"Custom watering can be anything from simply watering annual flowers, perennials to trees and shrubs for clients that certainly don't have service or are limited in that service because of water bans," explained Scott Senefeld, a landscape architect and partner at Sundown Gardens in Carmel.

Sundown Gardens doesn't custom water lawns, but Senefeld said he's still seen business increase 100 percent this summer.

The cost of custom watering varies, but it starts at about $35 per hour.

"We're actually fed from a well here on property, so we load our trailers or truck tanks here on property from a well, and then we go to those clients' sites and water," said Senefeld.

Senefeld said although it might seem like cheating to pay for custom watering during a ban, it's not.

"No, not at all," said Senefeld. "They have to get water from somewhere."
