On 3/21/00 at 4:15pm, Larry Riccio, the Director of the East Brunswick Sewerage Authority called about an emergency situation and asked if Middlesex Trenching could act immediately to take all action necessary to resolve the problem. By 5:00pm, MTC mobilized a 3-cubic yard excavator, two rubber tire backhoes, one 4-cubic yard wheel loader, two 18 cubic yard dump trucks, two 6" high veloci ty pumps, one 8" high velocity pump, one 6x10x14 foot trench box and 6 OSHA certified employees. Later that evening, MTC supplied 6 loads of QP stone from inventory.

Upon arriving at the site, it was apparent that there was a major problem and it would be necessary to work around the clock so additional supervision and personnel were called in. Waste was spouting out of an existing manhole 2 to 3 feet into the air directly in the middle of a major roadway. The first task was to control the spillage and install a bypass pump to relieve the overflowing condition. Once flow was under control, the area was fenced off, the roadway closed, proper barricades and detour signage were put in place and police stationed at each end.

After removing the asphalt, workers discovered the break had undermined or (washed away the earth) in the roadway 14 feet wide, 20 feet long and 7 feet deep. Excavation began with extreme caution as there was a major telephone duct bank in the immediate vicinity. A trench box was installed and excavation continued to a depth of 23 feet to the 32" sanitary sewer concrete pipe. It was discovered that the entire top half of the pipe had completely collapsed for a distance of 12 feet and was blocking the flow. The entire broken pipe was removed and a vacuum truck was used to remove tons of dirt from the downstream portion of the pipe.

Once all damaged sections of pipe had been removed the repair work commenced. The first joint was made pipe to pipe via factory joint. The second connection was a bit more tricky. It required a precise cut of the new concrete pipe which was than filled with a special rubber, Fernco and completely encased in 4 cubic yards of concrete.

The excavated earth was too wet to be used, so a field decision was made to backfill the area in 12" lifts with imported select fill in order to achieve a 98% compaction factor. Upon completion of the backfilling to sub-asphalt, a temporary asphalt patch was installed in order to open the road to traffic as quickly as possible and minimize any further disturbance to the general public.

The decision was then made to schedule final repairs to the roadway for a later date to allow the surrounding earth to dry sufficiently and allow for any unforeseen settling of the earth.

Middlesex Trenching performed the emergency repair professionally and without delay. Mr. Riccio personally called to thank Middlesex Trenching for it's professionalism and expediency in making a major emergency repair seem routine and praised it for exceptional service.
