Family of 5, 3 of which are little kids. When not irrigating we use 165 gallons a day. When the pool is full and the lawn is being watered, that shoots way, way up to over 7,000 gallons per day on days I run the sprinkler. Kind of stupid how much water we use for turf and landscaping.
Either water is dirt cheap/on a well, or you have a huge water bill

IIRC it roughly equaled out to $10 per 1,000 gallons for us, but I bet your yard looks amazing! We just let ours go brown...
