Tlnwni, Tunnel
The reason given for adopting n

pumping tho water over these hills,
which would bc necessary ~ the
pipo route were kopt dircct This
ehortuncd route through the tuu-
mol saves head which would be lost
IN n longer and more ruupdsh0us
rrnvliy line. This saving Of head
means n reduction In tho size of the
conduit.

The reasons for and sizes of these
units seem justified. The cost data
