The Pumping Station is a location in Jak II. It is an area north of Haven City consisting of a small island, cliffs, windmills, and large pipes converting sea water into fresh water for the city. It is accessible by a drainage pipe in the water slums or by using the air transport to the landing platform and moving south. Due to the construction of New Haven and the destination change of the transport, the pumping station became inaccessible during Jak 3. In Jak X: Combat Racing it returns as the Atoll Arena.
The Pumping Station was the site of one of Jak and Daxter's first missions in Haven City, when Torn sent them there after they had joined the Underground to turn on a water valve that the Baron had had switched off. The two found the valve and turned it back on, restoring fresh water to the Slums.
When Jak and Daxter were hired by Krew as wastelanders, they accompanied fellow wastelander Sig to the Pumping Station to hunt five Metal Heads. Sig's weapon, the Peacemaker, required charging before it could take out the beasts, and as a result Jak was required to defend him whilst he powered the gun. At one time the Peacemaker jammed, and Jak had to protect Sig while he fixed it. Eventually, all five Metal Heads where destroyed and Sig left to deliver the prizes to Krew.
The Pumping Station is the area that Jak and Daxter first met Ashelin Praxis. They were sent there by Torn when Ashelin disappeared. They eventually found her, though she claimed that she did not need help, but nevertheless allowed Jak to fight alongside her when they where attacked by Metal Heads. Once the attack was repelled, she showed the duo a stone with the symbol of Mar on it (the first time Mar was mentioned in the series) and explained that the baron had taken an interest in it. She gave Jak the address of the soothsayer Onin who could tell him more, and handed him a pass key to the Bazaar.
Even though it is unnacessible in Jak 3, it still exists as seen from the KG War Factory. Its appearance in Jak 3 is very different to the Jak II version of it.
An area surrounded by water and several small rocky islands jutting out of the ocean. Characterized by the large windmills and other technology that can be seen in and around the area. Most of the lower-level ground consists of sand, while the higher areas are all rocky plateaus with some grass and vegetation scattered throughout the level. There are quite a bunch of machines scattered throughout the area, most of them needed to reach otherwise inaccessible places.
Notably there is a second island close-by which can only be reached by using the Jet Board and crossing an old pipe. Then following a shortcut through a small canyon will lead you to the Dig Site and the Weapons Factory. This shortcut is labelled on the map as "caspad".
All of the Pumping Station's eight orbs can be found as soon as the player is introduced to this area. All of them can be obtained using the abilities Jak starts the game with and can be collected by the end of the areas first mission Find Pumping Station valve.
- Jak and Daxter first meet Ashelin here, and the character Mar is first mentioned.
- The Protect Sig at the Pumping Station mission was included on a demo disk given away with PlayStation 2's around the time of the game's release (September–October 2003). The other mission included was the Destroy Eggs in Strip Mine mission.
