Transfer stations are intermediary drop off locations often used where treatment facilities are located too far away from population centers to make direct disposal feasible. In other locations, traffic concerns or local truck bans during daylight hours may make transfer stations feasible. In addition, municipalities where a significant percentage of homes cannot be accessed by tanker truck should utilize transfer stations. Transfer stations are used if:
* More than 5% of the homes are inaccessible by a vacuum truck;
* The treatment plant is too far away from the homes for transport in one haul to be practical;
* Trucks are not permitted on the streets during the day; or
* Heavy traffic during daylight hours impedes the movement of vacuum trucks.
