Water and Lawn on rental home

[Jorge Avitia]

Hello again!

In the next three months I will be moving out of my home and start renting it out. It's a 3bed 2 bath SFH in a suburb of Austin, TX

I was wondering, in the area, is the water bill included in the rent? When I lived in an apartment back in 2010 I remember the water bill was a fixed amount every month, how does that work for SFH rentals?

On that same note, who takes care of the lawn and trees? My property has a BIG backyard and four very nice trees. Is it usually the tenant? a big chunk of the water bill in the summer is the watering of the lawn and trees. 

Thanks for any help!
