ICSERVICES JUNE, 1980 40! 10 . ORONO' S WATER SUPPLY POLICIES HAVE NO IMPACT ON METROPOLITAN FACILITIES TO THE EXTENT THAT ALL SUPPLIES , WHETHER INDIVIDUAL OR MUNICIPAL, CAN BE PROVIDED BY THE NATURAL SOURCE SUFFICIENT TO MEET ALL PLANNED DEVELOPMENT REQUIREMENTS . IIIWATER SUPPLY PLANS �I1. Individual wells will continue to be installed to serve all new rural fdevelopment and a majority of the expected urban residential development. 2 . Municipal water service extensions are not planned from the Orono Schools (Long Lake) or the Wayzata systems. ---�� 3 . No municipal water service extensions are planned beyond the existing Navarre Service Area. Local water service extensions within the existing service area may be installed by private developers, particu- larly in the area north of Shoreline Drive and west of Blaine Avenue (see Map No. 11) . Twnety four new units are expected in 1980 with additional land available for further development in the future . 4 . Each year more individual connections are made , particularly on the Navarre system. These will slowly raise the actual rate of usage of the system . 5 . Rate adjustments and/or service charge changes are under study to eliminate past deficit operating expenses in the water system. These studies may suggest mandatory connection , or more likely, the 11 institution of hydrant charges and differential rates for residential and non-residential users . 6 . A future municipal interconnection possibility is linkage across the 11 Narrows Bridge to Tonka Bay. This would have the same emergency protection advantages as the existing interconnections plus the advantage of tying together systems all the way from Mound (inter- connected to Spring Park) to Excelsior and east , thereby greatly expanding total emergency capacity and flexibility. In addition , Tonka Bay has indicated that their system has excess capacity and therefore is operating inefficiently. If there were ever to be a need for Orono to extend service into the remainder of our Urban Service Area, Tonka Bay' s excess capacity might be 11 available for use without expanding our treatment plant capacity , thereby benefiting both cities by more economical use of facilities. 7. The situation most likely to require first attention will be the correction of supply problems in the Orono Schools (Long Lake) system. Studies underway are not complete , but the range of solutions include I/ no changes at all to separation of the systems with Orono providing a completely separate well and treatment facility. The most cost effective solution would be some physical improvement in the existing cooperative system. 11 CMP 9- 17
