WATER SUPPLY

SERVICE FROM SULLIVAN DAM USE OF PROPOSED NEW MAIN In -view of the proposal to construct a new 14in pipe line from the Sullivan Dam to - give - a more adequate water supply to the high levels of the city, some information procured from the .city engineer by a ‘ Star ’ reporter may prove interesting. ‘ . The present 12in main and the 14m main, jf constructed, will supply some 40,000 people, or half the population who receive water. At the present .’time there is. a 9in pipe connection pff the T2in main, which discharges into the Ross “Greek Reservoir. The T4in main .would’ help considerably by maintaining a supply to the high levels from the Sullivan Dam, while water might bo fed-into Ross Creek by means of'the 12in main and the 9in branch to the Ross Creek Reservoir. There is also a 7in - and 6in main which runs from lower Morrison’s Greek into the Ross Creek. . What places does the Sullivan Dam ; serve direct? Does it help to supply Anderson’s Bay, Opoho, and St. Kilda, as well as . supplying places direct? were question put by the reporter. “There is a direct supply from the Sullivan Dam.” answered Mr Alexander, “ through the 12in pipe to part of Opoho. Dalmore, Woodend, part of Maori Hill, and part of Roslyn—in all a population of about 7,500. The remainder of the high level population (32,500) receives a supply also from the Sullivan Dam and tho WaitatiLeith catchment through the 12ih main* and the service reservoirs at, Maori • Hill and Roslyn! Anderson’s Bay is at present supplied from tho high level catchment through, the Maori Hill service reservoir. Part of Opoho is supplied from the Maori Hill reservoir, and, as stated above, part direct from the 12in main from the Sullivan Dam. Ravensbourne is also supplied from the Maori Hill reservoir. St. Kilda is not supplied from the high levels (Sullivan Dam-Leith-Waitati), but from the Southern Reservoir, which is fed from the Silverstream race.” The daily consumption per head,, said Mr Alexander to another question, varied with the weather. Fra- the twenty-four hours ended 8 a.m. on October 9 -last it was equal to 68.3 gallons per head.
