30 TUESDAY MARCH 24, 1981 The following are excerpts from a report entitled, "Raw Water Study for City of Martinsville, Virginia (March, 1981)", as prepared by Wiley & Wilson, Consulting Engineers, and presented by Mr. Tom E. Crush, P.E., of Wiley & Wilson, along with Mr. Garland Page and Mr. Charles H. Barnes of this firm, following which presentation Council directed that copies of the report be made available to the Henry County Supervisors and the Henry County Public Service Authority for their study, following which study the Council indicated its desire to receive comments and expressions from the Supervisors and/or the Public Service Authority: This report commissioned by the city to evaluate potential raw water sources has determined that an intake on the Smith River near Koehler offers the most cost-effective alternative which will produce adequate quality water and satisfy the water demands of the city through the year 2000. After completion of the facilities associated with this alternative, the city would have a 10 mgd source, transmission, treatment, and distribution system. Capital costs for implementation of this alternative are estimated to be $1,768,000 and annual operation and maintenance costs of $90,000. The Smith River raw water source alternative consists of a low weir dam, intake, and pump station to pump the raw water through an 18-inch main to the existing water filter plant on Jones Creek. The 10 mgd projected demand presently includes 1 mgd allocated for the county to be sold at a mutually agreeable rate. Until the city's needs exceed those projected herein, the city could provide the county, after implementation of its new raw water source, an amount greater than 1 mgd. The I mgd allocated and the initial excess supplied by the city would allow expansion of the county's system without the burden of large capital sums. In fact, once the downstream release criteria for Philpott is resolved, the potential exists for a much greater raw water availability at this point on the Smith River than the required 4 mgd. Once this amount is determined and if the need arises, the city's filtration plant at Jones Creek can be further expanded and a certain amount of this additional water can be allocated to the county. The intake on Leatherwood Creek is the alternative with the second lowest capital cost. This alternative would involve an intake and pumping station on Leatherwood Creek which would pump water to the filter plant. There are serious disadvantages to this alternative in that based on flow correlation with other streams in the area, the reliability of the source to produce the required yield during low flow periods is questionable. Also, the system would require large pumps due to the length of the transmission main and the static head.
