(b) Set up discharge pumps as shown in the figure below.<br />
Determine capacity and locations of engine pumps considering locations of the<br />
gutter to discharge the water and foot washing pond as well as size of the<br />
discharge hoses. Engine pumps with excessively large capacity could cause<br />
overflow of the gutter. In order to prevent such a case, it is suggested to use<br />
several engine pumps with medium to small capacities.<br />
(b) Set suction ports of the pump<br />
Set suction ports (nozzle of a hose to be set in the pool) so that they are set in the<br />
tank or tray depending on the water level in order to prevent pumping up the<br />
precipitate.<br />
