Harold's, Inc. Town of Southold Diversified Technology Consultants Name Harold Cook Keith Beardslee ATTENDEES Maintenance Review for Fisher's IslllI1d Sewer District! Wastewater facilities 98-067-200 I 1f ~c:? .<<'~ SU BJ ECT PROJECT NAME I PROJECT NUMBER 1. PUMP STATION A. A temporary trash pump is being utilized to pump wastewater. B. A spare Peabody Barnes Model 4X5034A pump is available at the pump station. C. It appears that due to high flows, the station has surcharged to within 5 feet of the top of the concrete i.e. elevation +7. D. Harold plans to install the spare pump first and keep the trash pump for back up until the two pumps that failed are repaired. E. He will remove both faulty pumps and send them to WISE, Inc. for repair. F. He estimated 10 days to get on-line with the first pump. G. The town approved emergency repairs- Harold contacted the WISE Co. H. The generator started and ran for 15 minutes successfully. *NOTE: No load was placed on it. CONCLUSION: Repair pump station. After repairs, I will inspect and pump test the station. Estimated to be on line with one pump in 10 days. 2. COMMUNITY LEACHING FIELD . Keith and the writer inspected the system. DIVERSifiED TECHNOLOGY CONSULTANTS 556 WASHINGTON AVENUE NORTH HAVEN CT 05413 2032394200 2032347376 FAX . ~ ----I---- ~ . LAND ENGINEERED STRUCTURES SOLUTIONS WATER REPORT OF MEETING A. The West side manhole of the influent distribution has about 3" to 5" of sludge in it and needs to be cleaned. No flow can be observed in the West tank inlet. .If a hose is used, keep the flow minimized to avoid suspending solids in the septic tank and damaging the leaching field. B. The distribution chamber was observed. The flow out of it is unequal. This is the flow distribution to the leaching trenches. We developed a low cost alternative for this correction. Adjustable plates should be fabricated and bolted to the existing V-notch weirs. Harold should give an estimate for this work. c. All 28 leaching chamber inspection manholes were located, opened and inspected. Depths ofliquid were determined in the ones with wastewater in them. . The following were observed: Number seauence is from Whistler Avenue. . Chamber No. l West: Dry Both Ends . Chamber No 2. West: 1 Foot of Liquid Both Ends . Chamber No. 3 West: Full to Bottom of Concrete (which is several feet from the surface) . Chamber No. 4 West: 1 Foot of Liquid . Chamber No. 1 Center West: Dry Both Ends . Chamber No.2 Center West: 2 Feet Deep Both Ends . Chamber No.3 Center West: Dry Both Ends . Chamber No. 1 Center East: Dry Both Ends . Chamber No.2 Center East: Dry Both Ends . Chamber No.3 Center East: Dry Both Ends . Chamber No. 1 East: Dry Both Ends . Chamber No.2 East: 2 Feet Deep, High Flow into it . Chamber No.3 East: Dry Both Ends . Chamber No.4 East: Dry Both Ends TOTAL: 14 SETS OF GALLEYS -1 Full (#3 West) -(2) 1 Foot Deep (#1 and #4 West) -(2) 2 Feet Deep (#2 CenterlWest) (#2 East) -9 Dry Galleys DIVERSIFIED TECHNOLOGY CONSULTANTS 556 WASHINGTON AVENUE NORTH HAVEN cr 06473 2032394200 203234 7376 FAX . ~ ~ ~ . LAND ENGINEERED STRUCTURES SOLUflONS WATER REPORT OF MEETING CONCLUSION: The system is not overloaded in total. The West side is taking too much of the flow. Keith should check chamber #3 west once in a while to determine if the liquid rises. Meanwhile, adjust the flow away from the West side to alleviate this condition. SOLUTION: Provide simple distribution adjustment. Fabricate (3) 1/8" thick stainless steel V-notch weirs and install. Harold to provide an estimate of time and materials. WHAT NEEDS TO BE DONE: I. Maintain the plugged manhole by removing sludge or washing and snaking the system. 2. Mow after summer season 3. Plug holes in covers if necessary during late summer if odors are evident. 4. Monitor Chamber No.3 5. Modify the flow distribution to flow East 3. STORMW ATER FROM FOX LANE . Four catch basins are connected to the storm sewer which empties into the sanitary. Temporary plugging should be evaluated. We must assure stormwater does not flood anything near Fox Lane. 4. POTENTIAL SYSTEM LEAKS . Check the manhole near GADA's old building to make sure that the sound waves have not reopened the brick and mortar bulkhead allowing seawater to enter the system from the abandoned outfall. . We attempted to inspect the manhole at the end of Fox Lane near the shore. This manhole could not be found. 5. PUMP STATION FOLLOW UP: . After the pumps are installed, the writer will test the pump station. .:. This is the first part of the maintenance and operation review project. pc: Harold Cook, Harold's Construction Co., Fisher's Island wi Enclosure Justice Louisa.Evans, Fisher's Island wi Enclosure Michael Casey wi Enclosure S:\911067\200\ReportofMccting\062498.doc DIVERSIFIED TECHNOLOGY CONSULTANTS 556 WASHINGTON AVENUE NORTH HAVEN CT 06473 2032394200 203234 7376 FAX . piP' 12.
