3800: Sewer Works Sink
Riaño 30T 451023 4800683 (Datum: ETRS89. Accuracy code: A) Altitude 110m
Area position

A stream sink taking a fairly substantial stream in moderately wet conditions, which flows from the south and also takes the discharge from a new sewage plant nearby. The stream sinks in sediments with no hope of easy access at this point. In flood the stream overflows to another sink adjoining cave 3299.
The stream presumably joins the stream in Cueva Espada at some point.
