The Haven sewers is a sewerage system in Haven City visited in Jak II and Jak 3, later appearing as a race track called the Sewer Raceway in Jak X: Combat Racing. It appeared to serve as a waste management and water supply system, as the term "sewer" implies, possibly having connections to the Port and pumping station. It is accessed via an elevator, usually located in the Industrial Section, although in Jak 3, other elevators have been accessed in Main Town, New Haven, Metal Head city, and the Port. Generally inhabited by hostile creatures, it is normally considered a hazardous zone.
