The round black lid in your front yard is not a sewer cover, that is your meter box and our meter boxes are very deep due to the freezing temperatures (see picture). They also require frost protection and we achieve this by inserting a foam disc into the meter box (see picture). We ask that you do not enter the meter box and do not use our curb stop (on/off valve). We ask that you use your stop and waste valve to turn your water on and off. If have any questions regarding this information or you notice that you are missing your frost protection, that your meter box is damaged or the lid does not fit properly on the box, please call the office immediately at 909-585-2565 and a service technician will be dispatched.
