Hi Bill, I don’t have a straight forward answer for you because it depends on the year they hook up since our rates are currently set to go up every year. However, we can make some general assumptions that their 0.30 million gallons day would occur in 2028 at the earliest. In the Oct to April months the bill would be around $33,000 a month and in the May -Sept it would be approx. $53,000 a month based on outside City limits. They would also pay a base rate which is dependent on the size of meter they would use which also increases each year. I’ve included the water rates that shows the tables for both base rates and volume rates. Thank you, Katherine Katherine Miller P.E.
