The Two Streams Kindness Facility was a hospital on Apalapucia designed to care for Apalapucians who had contracted Chen-7, a plague that would ordinarily kill any two-hearted being in a day. The facility was designed with two goals in mind: quarantine of the infected to stem the spread of the plague and palliative care for infected Apalapucians.
Two Streams achieved both with temporal technology. The infected were sent to live in separate time streams "compressed" from the main one. They were held in place by "temporal engines". The compressed time streams were collectively known as "Red Waterfall" and the single normal one was known as "Green Anchor". There were emblems for each. Amy Pond once got separated from the Eleventh Doctor and Rory Pond there, entering a different time stream to the one they had entered.
