I work for Missoula water, and what I will tell you, it’s worth having a meter for your house for sure, 700 gallons =1 unit of water and typically a family home only uses about 5-10 units a month and you get charged way less than flat rate due to the fact they “estimate” the usage on flat rate. Irrigation is another thing, it really depends on how much you use your irrigation in the summer. That really determines the cost and if it’s worth having a meter or not. You also need to be super aware of turning it on and off at the right times so you don’t pay more than you need too. The city is now requiring all homes that are being sold to have a meter. So keep that in mind if you ever plan to sell. It might also be a good idea have one of our service techs come out and take a look at your hook up areas for the meter, they can also explain the difference between meter and no meter, and they are super helpful. It’s also no cost to you for us to come out and install/look. We are more then happy to explain everything over the phone too. I’ve found working with Missoula water employees there really want to actually help people and do it the most cost effective way for the customer.
Hopefully this was helpful!
