XXL Combined Stormwater Overflow Detention “Tank” sorry it is a reservoir. See the in and outlet in the back
In and Outlet for the stormwater – start will be in one month from now
CSO Chicago starting 2017, XXXL size, never seen before
What a scale of projects. I have seen the second largest combined stormwater overflow detention tank in Europe in Munich which has the size of two scoccer places. The new CSOs in Chicago is from a different star. One will be ready in one month and the second one will be ready, after 10 years of construction, in 2017.
These two big open reservoirs will serve the City of Chicago and will hopefully prevent the city by beeing flooded by heavy rainfalls. 40-50 storms a year occur. The deep tunnel project releases the normal sewer system and takes all overflows down into the ground. The length is about 150 km. The deapest point are the XXL Pumping Stations. There the water gets pumped up and gets treated.
Drying beds in Chicago – ready for agricultural use
Drying beds – heavy machines are at work
Wastewater Sludge is storaged in big drying beds. Heavy machines are in action and the dried sludge is used in agriculture after certain time.
Again the the size is impressing. Germany has 9500 Wastewater Treatment Plants but certainly not that size for drying beds, we just do not have the space for that.
120 m deap pumping station for the intake to the Wastewater Treatment Plant
American technical language is a challenge for the German guests
XXL Pumping Station & Sewer System – deep tunnel system, 9 meter diameter, 150 km long
A nice day out. Ed and Joseph, incharged of the sewer system of Great Chicago showed us a XXL big pumping station at Calumet Water Reclamation Plant. 120 under the ground. A 9 meter pipe comes in and the wastewater has to be pumped a 120 meter higher to the wastewater treatment plant. One of the 7 plants serving 10 Mio. people in the region.
What a show. US dimentions are bigger than at home. A great experience, and nice collegeus. Joseph even talked a brilliant German and explaint a lot.
WEFTEC Training in Düsseldorf June 2015
In June 2015 two German Wastewater Teams met in Duesseldorf to train for the WEFTEC Operators Challenge in September 2015 in Chigago/USA.
DWA has good relations to the US based Water Evironmental Federation (WEF). Last year I visited them during my holidays. This year the CEO Eileen visited us in Hennef. We agreed that I would try to get one team over to the annual Operators Challenge and the year later one US Team would come to the IFAT 2016.
Now I could get two teams, one from the city of Duesseldorf and one “All Star Team” from the cities Duesseldorf, Bonn and Nuernberg. The Duesseldorf Team is a team with young professionals where the All Star Team is more senior. They all work in wastewater utilities and are excellend people. Most of them pay the flights themself and take holidays for this trip.
To travel to the US skills competition is something special and all members are exited, so do I. I´m the coach and translater. We will have a competion with 44 Teams – it is the first time that a German Team visits the WEFTEC. I have been to the WEFTEC 2013 in New Orleans and I saw there competition already. I´m looking forward to this nice experience and let us have fun and to learn from each other.
Thanks to the IFAT Munich who help us as the main sponsor for one team and thanks to the City of Duesseldorf to send their Young Team and to enable us to have this training done.
