Potters Bar is in the Hertsmere district of Hertfordshire. Wikipedia says it stayed a small farming settlement until the railway arrived in 1850. Its population then grew from 13,681 in 1939 to 24,613 in 1971. As a result, many homes date from the twentieth century.
The EN6 postcode also covers South Mimms, Cuffley and Northaw. These places sit in different council areas, and not every home is on the mains sewer. If you are unsure, check with your water company. For example, a pipe that serves only your property is usually yours to maintain.
