April 15, 1966
ABSTRACT
It has been proposed that underground discharge of effluent from a sewage treatment plant at Waimanalo be substituted for discharge through a long and expensive ocean outfall. As a contribution to the determination of feasibility of underground discharge of the treatment plant effluent at Waimanalo, and in accordance with an agreement reached at a meeting at the Division of Water and Land Development of 16 December, the Water Resources Research Center arranged a conference on the sanitary aspects of the proposed installation. The conference was held on Thursday, February 24, 1966 at the Hawaii Institute of Geophysics Conference Room at the University of Hawaii. In attendance were the following: D.C. Cox-U.H., Hiromi Okuda-C.C.H., N.C. Burbank Jr.-U.H., Chew Lun Lau-C.C.H., James Yoshimoto-DOWALD, E. H. Broadbent-R.M. Towill, A.Q.Y. Tom-U.H., B.J. McMorrow-S.H.D., Francis Aona-C.C.H., Francis Woo-S.H.D., Shinji Soneda-C.C.H., James Nakahara-S.H.D., Albert Tsuji-C.C.H. In summary this memorandum includes the discussion of the salient features under consideration. Three items of major consideration in the proposed Waimanalo Effluent Disposal project were indicated. These were (1) a program to characterize the sewage, (2) consideration of the offshore monitoring program and (3) future studies required.
