I PROJECT APPROACH I SCOPE OF SERVICES This project involves providing engineering services to the City of Mounds View for an analysis of the water storage needs for the City. The study will use the existing 111 calibrated Ky Pipe computer model for evaluating the possibilities of: A. Elimination of tower no. 2 from the system. 11 B. Replacement of tower no. 2 with a smaller tower. C. Elimination of tower no. 2 from the system and replacement of tower no. 1 I (and sizing this tower). D. Elimination of tower no. 1 (and/or tower no. 2) and adding a new tower in the northeast part of the City (and sizing this new tower). The City of Mounds View has a calibrated Ky Pipe computer model which has peak demands at all the nodes. This model will be used for the analysis. 1111 During the study a complete understanding of the operation of the water system will be required to interpret the computer output. Consequently, several meetings will be held U during the course of the study with the operating and engineering staff of the City. At the conclusion of the study a report will be written which will include recommendations for a course of action regarding the water storage needs, location and sizes. Mounds View Water System The City of Mounds View is presently served with 6 wells, 2 elevated storage reservoirs and one 2 million gallon ground storage reservoir, and a distribution system consisting of 4-inch watermains and larger. Well no. 4 presently is the only well that does not have treatment. This well is used infrequently and is a candidate for replacement/abandonment. The City is presently constructing a water treatment plant near the City Hall which will treat water from well nos. 1, 2 and 3. Tower- no. 1 presently- has --severe structuraldamageand is in need of extensive structural repairs. Tower no. 2, located in the southeast corner of the city, is also in need of minor structural repairs. Tower no. 2 has consistently maintained higher water elevation than tower no. 1 because of lower demands in the vicinity of the tower. Both towers have lead based paint which is very expensive to remove and repaint. The study now being II proposed will evaluate the adequacy of storage provided by towers 1 and 2 and the -need for retaining, increasing and/or abandoning the-existing elevated storage,-and-the need for a new storage facility in the northeast corner of the city.
