This was put into operation only eight hours a day. As all the problems in the system were not yet solved, our operator did not feel it was wise to leave it in operation with none of the Plant personnel present. The addition of the tertiary treatment has caused a sudsing problem of our effluent resulting in soap suds foaming out of the standpipe near the lake where a chamber was built to take air out of our effluent line going into the late. The matter was referred to our consulting engineers, Teetor- Dobbins, for recommendations as to how to handle this problem. Contractors for the additions to the Plant are still working to complete their con- tracts. Although there is little to do, the effort on their part seems to be drag- ging, and we are not yet in a position to have an inspection. Teetor - Dobbins has held job meetings with the contractor and is pressing them to complete their work. With the tertiary treatment in operation, our, contract sewer plant operator will submit an estimated cost for operating the plant with its expanded treatment. His rough estimate at this point is $18,000 additional per year. He will submit in writing his proposal to the Board for operating the plant with all alterations and additions completed. The heavy rainfall of September 25 and 26, which was estimated as a once- in- fifty- year storm, caused the flow at the plant to exceed its capacity of 7 mgd. No damage was done at the plant, but there was overflow. SEXIER LINES The September 25 -26 storm caused extensive infiltration to the sanitary sewer lines. The major portion of this came from the Lansing area. Definite infiltration into the manholes and from the aides, bottom, and top were found in the new sewer line laid to service the new Morse Chain plant. Their engineer was notified of this problem. Although we cannot hope to eliminate the infiltration caused by a once -in -fifty -year storm, continuing efforts are made to try to find where this amount of water did enter our system. Flow over tops of manholes caused some of the problem, and work is being done to eliminate this where possible. With this high flow, the manholes in lower Remington Road did overflow. This was the only part of our sanitary system that did overflow, and the Lansing engineer has been notified of this in relation to the notification last month to the Village of Lansing that capacity of this line was limited as to carrying additional sewage from the Village of Lansing. STOP14 DRAINAGE The storm of September 25 -26, although intense, caused only one major problem in our • storm drainage system. The culvert under N. Triphammer Road near Winthrop Drive backed up to the point of overflowing because of concrete form work that was in place in preparation for building a new headwall for this culvert. Pumping in an effort to reduce the accumulated water was not sufficient, and it was necessary to move all the form work. The culvert then carried the water with no problem. This headwall has ro:; been reformed and poured and is complete. page 2 - Report of Engineer, 10/20/75 • STORM DRAINAGE (cont'd) Mr. Schoenfeld has reported that the drainage for his new sub- division, Cambridge Place, as approved by the Board, will flow over a piece of property fronting on Warwick Place. He has recommended that instead of an underground culvert, the ground be shaped to take the water on the surface. He further contends that this is a Village problem in that the land was properly shaped at the time he sold the property to a house builder in the Williamsburg Park area. That later this builder secured a zoning permit and proceeded to fill the area left for drainage with inadequate sub- surface drains. This was done in about 1960. Mr. Shoenfeld's plot plan and letter will be available at the Board meeting. Mr. Schoenfeld furb%r recommended that the Board request the Village of Lansing to divert water to the north where it once flowed before there was some road development northeast of the Village of Cayuga Heights. Maps will be available at the Board meeting for the Board's information. This request to the Village of Lansing is recommended by the Engineer. Mr. John Petrillose of Triphammer Road has requested that the stream on his property and his adjoining neighbor's property be dug out by the Village as sediment has bad a tendency to back up water causing flooding his basement. He was notified that this did not seem to the Engineer to be a Village problem, but that the matter would be brought to the attention of the Board. Also, a storm drainage problem was reported by Judge Bryant of Northway Road. The matter was investigated, but no problem with Village facilities was found. STREETS • Sheldon Road paving is now completed, including the shoulder work and replacements of driveway culverts where necessary. Cost of the pipe is borne by the adjacent pro- perty owners. The water line contractor for the Bolton Point Water System is in the process of putting the final paving on the road excavations done by him throughout the Village. The finished job looks very good at this point, but the Engineer is concerned that additional settlement will occur within the next year or two causing the need for additional patching. LEAF REMOVAL Two trucks are available with leaf suction devices, and it is hoped the work crew will be able to keep up with the removal of leaves as they are put out for collection. PERSONNEL Mr. Delbert Grover reported back to work last Monday, October 8th, after extended sick leave. Action by the Board on a sick leave policy is recommended by the Engin ear. REPORT OF ZONING OFFICER During the past month, one zoning permit was issued for the construction of altera- tions and additions at an estimated cost of $200, and one permit was issued for the construction of a new single- family residence at an estimated cost of $48,000.
