Hanoi System
The Hanoi system was first presented by Fujiwara and Khang (1990) and is based on the planned trunk network of Hanoi, Vietnam. There are 34 pipes to be sized with a total length of 38.61 km. Possible new pipe sizes range between 12 and 40 inches and the total system demand is 126.5 MGD.

Modified New York Tunnels System
The New York Tunnels system of the previous case modified to include chlorine concentrations. The minimum required chlorine concentration was assumed to be 0.3 mg/L and the chlorine dosing just downstream of the reservoir could be set to lie between 0.5 and 2.5 mg/L. The average daily demand was 1305 million gallons as in the original New York Tunnels problem (above).

New York Tunnels System
The New York Tunnels System represents the major water supply transmission tunnels for the City of New York in 1969. The system consists of 1 reservoir (Hill View) and 21 tunnels with two loops. The total length of tunnels is 69.2 miles and they range from 60 inches to 204 inches in diameter. The average daily demand of the system was 1305 million gallons.
