a. what is the tunnel annel (4 marks)
TARP, Also known as "deep tunnel" was a2 phase plan started by Chicago in the 197s.the 2 phases were anti pollution and anti flooding. < A meter, capacity and depth of the tunnels underground. (3 marks)
Chicago's tunnels have 131 miles altogether, Some going as deep as 35 feet with diameters from nine to 33 feet.one-hundred-ten miles came from the anti pollution phase, And 21 miles from the antiflooding phase.the antiflooding phase also brought 3 large reservoirs.
C. list four beneficial reservoirs Arks)
Chicago's sewer system brings many benefits.first, it provides storage for water so as to not overload treatment The release of untreated water into nearby water sources is eliminated.third, Floods are controlled to stay off the streets and out of basements.fourth, water pollution is minimized.
