Agent, this is Subject 1. We have found infomation that a scientist is using sewer water for somthing. He has built windmills that absorb the water and put it in their pipes. The pipes must lead to the science lab, so we've dug up one on the windmills pipes. Your mission is to go through the pipes and find the science lab. Once you complete the mission, return to the starting point and find an escape pod. Good luck, Agent.
