Not to say your analysis is flawed, but SFPUC rounds everyone&#x27;s water usage to the nearest &#x27;unit&#x27; (748 gallons) meaning that anyone who uses less than 748 gallons&#x2F;month is paying at least €8.05&#x2F;kiloliter (based on my consistent $25&#x2F;one-unit bill.)<p>As a single guy, I consume nowhere near my allocated 748 gallons&#x2F;month, meaning my effective rate is even higher.
