NJAW completed work
- October 13: Install jersey barriers and secure the work zone. Prep for excavation.

- October 20: Shut down the 36” main on Altamont Pl and install the new tees and reducer. If there is time, Vollers will tie in the existing 8” main to the new 36” x 8” tee. NJAW will be going around the clock until the 36” main is turned back on.
- October 21: Tie in 30” main into the 36” main. Pour concrete kickers.
