March 2007 Effluent Monitoring Data

 

During the month of March there were no license exceptions to the NVC monthly discharge license.

 

Of significance, flow averaged 27,039 gpd. TSS averaged 2 lbs/day and BOD average 4lbs/day. All of these were well below the DEP permit limits.

 

See performance table below for comparisons, averages, year-to-date highs and lows, permit limits, and year-to-date violations.

April Snapshot

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

With not all the data in, it is too close to call as to whether or not the NVC will be in total compliance of its discharge license in April.  Flow as of April 26th was averaging 58,000 GPD or just under the NVC Permit allowance of 63,000 GPD. Almost one-third (0.5 million gallons) of this average flow came during the two days the Village experienced heavy rains and the storm surge. Based on the pictures submitted to Dan Webster’s website, the unusually high tides most probably caused tidal water to backflow into the plant and a creation of false positives through the V-notch weir effluent flow monitoring box. 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

CCTV Inspections of Sewer Lines

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Ted Berry, Inc videoed selected sewer lines for condition and clean water infiltration on April 18 and April 19. One source of significant infiltration of about 6-7 gpm has already been removed at 770 Shore Road. Property owner McArthur, together with agent Bill Paige and contractor Dean Brown, moved quickly to complete the replacement of the home’s service laterals on April 25 where the leak was found. Mr. McArthur is to be commended for his quick action in getting this repair done. In addition, the discovery of a buried perforated manhole cover in Auditorium Park has also been replaced with a solid manhole cover.

 

Other findings that await action include the following:

 

  1. a leaking manhole (MH 2000A) across from the Yacht Club of 3-4 gpm

  2. a below ground and collapsed manhole (MH 1020) between 1 and 3 Park Row

  3. a heavily rooted and leaking stretch of VCP pipeline running behind the Blair Agency to the Yacht Club of 4-5 gpm (MH 2005-MH2010)

  4. 4 leaking service laterals along the Shore Road totaling 2-3 gpm

  5. a 120 ft section of VCP pipeline at the very end of the main sewer line on the Shore Road of 3-4 gpm (MH 3120 to the end)

  6. 3 leaking service laterals at the corner of Pleasant and Broadway

  7. a leaking pipe joint at the base of Auditorium park of 3-4 gpm

  8. a stretch of about 500 ft of main sewer along Bayview Street in bad need of flushing and vacuuming

  9. a leaking and rooted VCP pipeline on Bayview St between MH 2020-MH 2018

  10. a leaking root ball and pipe joint on Oak Street

 

Inspections of Cobe, Maple, Clinton, Pleasant and North streets were also performed. However, because of the steep inclines, limited access points and narrowing pipelines, the cameras could not reach far enough in to locate the sources of infiltration on these streets.

 

Moving forward with what services Ted Berry, Inc can provide to the Village, the company recommends trenchless/pipebursting solutions to replace the stretches of piping (160 ft) behind Blair’s and the end of the South Shore Road (120 ft). To provide more access points, Berry recommends the NVC install 6-inch two way cleanouts at upstream points to the gravity lines of the aforementioned streets to enable future camera work in these areas where infiltration has been observed as being heavy. And finally, their last recommendation is to clean, flush and vacuum out the collapsed manhole and section of main sewer running along Bayview. Waiting too long to do this or not doing it could cause a sewage backup.

 

The full report from Ted Berry, Inc., including the company’s cost estimates to complete these recommendations, is still under review. McElhaney noted that we have money for improvements left over from last year with another $30,000 budgeted for this year. Jo Huntoon (NVC President) suggested that we talk to Julian Sheffield (NVC Treasurer) about taking a loan against these accounts for making the improvements instead of spending it up front.

 

With the remaining findings, the NVC Sewer Department will notify the affected homeowners whose lateral connections are leaking and contact outside contractors to repair the damaged manholes and the other leaks found in the main sewer lines.

 

Outfall Pipe Inspection

 

The Department is currently attempting to schedule with a diver the annual inspection of the plant’s outfall pipe before May 15, 2007. DEP requires this as part of the NVC consent agreement.

 

Chlorination/Dechlorination

 

Fernie is preparing the chlorination/de-chlorination system to bring that system back on line for the season. DEP requires the effluent to be disinfected to kill off disease causing pathogens during
