These improvements would assist materially in eliminating the present deficiencies In water pressures. Further improvements required as the City grows are shoLm on drawings Noo 5. In addition to the Improvements shown., the distribution system, *within the l.00pa as shotm would be greatly Iaproved by replacing iho 4 In '1 lines with b inch linos in the residential areas., and with 8 Inch lim. the mercantile district. The difference In elevation between the Bozeman Creek Reservoir and. tho Lyman Creek Reservoir makes it necessary to have some control on the Bozeman Creek lino in order that at periods of low demand the Bozeman Creek reservoir would not drain into the Lyman Creek reservoir and be wasted .through the overflow, Consideration was given to replacing the Bosemsn Greek Reservoir at a long elevation., h waver., this proved to be unsatisfactory from the standpoint of preset ves at the Montana State College. With the loops laid out an shorn ca mpensation for the differ— enoe in elevation between the two reservoirs could be made by installing pressure regulating valves on the supply lire below the point of take—off for the line serving the College. This would result in keeping the relatively high pressures for the higher areas South of Col.lebo Street, and would also eliminate the necessity of having eeaeral pressure regulating valves to maintaino —42— 17 COST ESTD TEM, The Improtoa:mts in tho distribution system outlined above will very probably not be u2dertakon as a cmploto projeot, but will be done 3n sax11 sections as the need for then increnos.
