Rio Monterroso

the Rio monterroso is a river in Estepona Malaga southern Spain that runs approximately 7.5 KM (4 mile) that runs off the Bermeja mountain that runs through farms down into The estepona province Into the industrial estate where it flows underground into a tunnel the avenue duan Carlos 1 and flows on estepona beach meeting the sea.

Tunnels

The Rio monterroso flows into a man made tunnel that is 1.1km long (0.684 miles) until it reaches the end Out of the paseo maratimo And onto the beach. The tunnel was constructed approximately 60s or late 70s or early 80s Along with 2 other tunnels arroyo melonar and arroyo Calancha The tunnel can not be trespassed So if you went in there and called the police they will only say get out the tunnel they probably won't even say that unless you are commiting an act of vandalism

Time of flow

The Rio monterroso means river monterroso and arroyo de monterroso means stream monterroso in the summer the river turns to a calm trickle and eventually stops and gets blocked up by plaster reinforced with twigs to stop it from stinking and drunk/poor/vandalism people from entering the tunnel.

Dangers

Last month estepona flooded and that meant 6ft2 tall sheets of water wash rushing into the tunnel and out at very high speeds and a recorded amount of 2.5 million tons of water every 5 minutes and a drunk person could fall into the inlet and get washed away to sea and drown or get there head crushed and smashed on the support beams while making the water go red and hearing a slamming sound under the road Stormwater care

Inside the monterroso tunnel are many holes that lead from storm drains and big storm sewers into the tunnel aswell as when it rains in small fields and forests and creates a small stream that flows into the pipe and into the tunnel.

Watermain burstage

In june when the trickle of water stopped flowing they painted the sewer drains and put a plaster cover on the outlet temporarily. They also started building a waterfall on the avenue Juan Carlos 1 and on June 27 2018 they accidentally punchered or purposely broke the water pipe to probably test the connection to the waterfall.
