About Water Purification Station

Changgen Yang

Main water purification station. It is too high in this plot, we would like to change to ~4m. It is located 50m south of the intersection point of the construction tunnel with main tunnel

Further calculation needed to see if we can share thepump in the circulationSystem - it may waster energy to do so since the lift path needn’t be large.l

A One may use the same pump for water circulation and water transfe

r between pool 1~3 and pool 0, but these pumps may different for different purpose.

B It is possible to use the tunnel seepage water if we add a pre-treatm

ent at least to filter the seepage water, the estimated cost is about 30k$.

C One can put all the pumps in the sump, the sump exit can be in the

EH (crane access easier but ditch will be needed from water circulation room to the sump ), or in the water circulation room (no crane and no ditch). Put the water circulation pump in the water pool may not good because it’s operation might cause noise to the PMTs.

Move the pump pit to the other corner of the pool or directly to the water purification room? (need a crane to lower pump)
