- ~ ~1 TUESDAY AUGUST 25, 1981 be constructed and inter-connected with the City's facilities. The total estimated cost of these improvements is approximately $39,100. However, it should be noted that, at the present time, only $11,500 of this amount is required for proper distribution of water and equalization of flows. Therefore, a total estimated construction cost of those facilities necessary to serve the City of Martinsville with an additional 1.8MGD is less than $150,000. As to the hydrolics involved and the effects of the above-mentioned improvements upon the City's water system operations, it has been estimated that an additional pressure of 15 pounds per square inch would be realized by an input of 1.8MGD from a proposed County booster station, a relatively negligible increase in pressure. It is not anticipated that this increase in pressure would have any adverse effect upon the City's system nor upon its customers. In fact, such increase in pressure may well affect certain sections of the City with better fire protection and better water service. As to operational costs, it has been estimated that the yearly power costs for the above-described facilities would be between $15,000 and $20,000. As to the question of whether or not sediment would be disturbed in the City's water mains as a result of providing the City water from the Marrowbone Creek facilities, it should be noted that the City of Martinsville has prudently serviced and pumped its water mains for many years in order to rid the system of such sediment. However, should such sediment be disturbed as a result of reversed direction of flows, an advanced or accelerated flushing program could be adopted in the early stages of operation in order to rid the system of such discolored water. It should be noted that, with the additional supply of 1.8MGD from the Marrowbone Creek facilities, more water would be available to the City for such flushing operations and would eliminate the necessity for the use of the Beaver Creek supply for this purpose. Should the City of Martinsville decide that it requires a flow in excess of 1.8MGD, the Authority's treatment facilities could be expanded and additional pumping capability provided in the above-mentioned pumping station; and a total of 2.8MGD could be furnished by the same means with an increase of only 36 pounds per square inch on the City system. Still further, with an increase of flow to 3.8MGD, an additional pressure on the City system would only amount to 64 PSI. Even this could be reduced by the addition of other improvements within the City's water system. It should be further recognized that, with a concerted and cooperative effort on the part of both the City of Martinsville and the Henry County/Public Service Authority, other improvements could be made to accommodate the City's needs via the construction of other pipes and pumping stations to provide routing for the distribution of flows and
