Municipal Drain
Perhaps you've just purchased property, and been told by your municipality that you are assessed into a municipal drain. Perhaps you have owned a property for a couple of years and have recently discovered that you are located in the watershed of a municipal drain. You're probably wondering, what does this mean? How does it affect me? What will it cost?
Physically, What is a Municipal Drain?
Physically, a municipal drain is simply a drainage system. Most municipal drains are either ditches or closed systems such as pipes or tiles buried in the ground. They can also include structures such as dykes or berms, pumping stations, buffer strips, grassed waterways, storm water detention ponds, culverts and bridges. Even some creeks and small rivers are now considered to be municipal drains. Municipal drains are primarily located in rural agricultural areas of the province.
