(a) Pump up water and precipitate left on the bottom of the pool into 1 ton plastic
tanks.
Find a drain port on the bottom of the swimming pool and wipe precipitate with
water using wipers toward the drain port (photos below) while pumping up
precipitate with water at the drain port using an engine pump into 1 ton plastic
tanks. Avoid pumping up water only, because it leads to a difficult condition for
the precipitate being pumped up. Make efforts to pump up precipitate as much as
possible.
Wipe precipitate with water using wipers toward the drain port
while pumping up precipitate with water.
Pour the pumped up water containing precipitate into the 1 ton plastic tanks as
shown in photos below.
