Prior to the arrival of the IMC, this was one of several water collection and treatment facilities owned by a neurtal terraforming company attempting to secure territorial rights, before publicly announcing their discovery of this world. Now these operations have been silenced and placed under IMC control, in service to the new IMC Fleet Operations Base under construction several miles away. Overhead, the remnants of the IMC fleet on the Frontier can be seen arriving sporadically, headed towards the new base for replenishment and repairs. In response to garbled distress signals sent by the original occupants of the facility, the Militia deploys a recon fleet to investigate.
The water processing and drainage from this facility are what was responsible for the unveiling of alien ruins in the Swamplands nearby.
