The
Period of Gongguan Purification Plant
 Upon
the implementation I 1977 of the Taipei Area
Water Supply Expansion Plan, Phase Ⅲ, the
original slow filter was rebuilt into the
modern rapid filter with a new name, the Kungkuan
Purification Plant. Years later, however,
worsening pollution of water sources forced
the raw water intake to relocate from downstream
of Xindian Creek to the Qingtan Dam upstream.
Natural, gravitational forces carry raw water
taken in there through tunnels and channels
to the diversion chamber in the Changxing
Purification Plant. From the diversion chamber,
two 1,400 mm concrete pipes and one 2,000
mm cast-in-place reinforcement concrete pipe
deliver the water to the Kungkuan Purification
Plant for treatment.
With a design production capacity of 480,000
ton per day, the Gongguan Purification Plant
treats 520,000 ton of raw water daily. Decent
potable water after a long, complete treatment
process is then delivered by heavy-duty booster
pumps to distribution piping system to serve
daily needs of end users in the Taipei area. |
