Here's the latest communication from the NHSA on the Wet Weather Pump under construction downtown. This solution is highly anticipated and is working through some complications on clearing tubes connecting to the pumping station to pump out the water. A key timeline is completing at least one of two by October with insertion of linings. The work is hard and needs to be completed on delicate piping manually. It's pretty rough going from the sounds of it and another crew is being added to push it ahead.
If this plan continues along the proposed timeline, some much needed relief will come online by the middle of October with the other half early to middle next year.
The document is a memo to the NHSA Chairman Richard Wolfe.

MEMORANDUM
Status of H1 Screening and Wet Weather Pump Station
TO: Richard Wolff/Chairman/North Hudson Sewerage Authority COPIES: North Hudson Sewerage Authority Board of Commissioners FROM: Michael Wilson, P.E., Project Manager, CH2M HILL
DATE: August 15, 2011
Chairman Wolff:
As requested, we are providing the monthly update regarding the progress of construction of the H1 Screening and Wet Weather Pump Station project. This update is for work that took place during the month of July 2011.
The contractor’s most recent progress schedule is dated August 10, 2011. The progress schedule reflects continued completion of the few remaining elements of work associated with the pump station and electric building, as well as continued startup of new equipment and systems. Significant cleaning and inspection work on the western pipeline was achieved during the month, and activation of the west pump and western pipeline is still anticipated for the fall 2011. As noted previously, activation of the western pump and pipeline is contingent upon timely completion of the pipeline restoration work. Section C provides a comprehensive schedule narrative and commentary. The following is a summary of important project issues, milestones achieved, and the most recent estimate of the project schedule:
A. Important Project Issues
1. Outfall Rehabilitation and Extension: As noted in previous monthly reports, completion of the permanent rehabilitation of the existing outfalls is required for operation of the pump station. This is the most complex portion of the project, and it continues to impact the schedule for placing the pump station into operation. During this reporting period the contractor began full- scale cleaning and inspection work in the western pipeline. Initially, the cleaning and inspection work progressed well, with few impediments to the progress of the work. As the contractor neared the middle reach of the pipeline they encountered areas where the solid deposition material was extremely difficult to remove, which considerably slowed the pace of work. Following our request starting the week of August 15th the cleaning contractor will mobilize a second cleaning crew to increase productivity and progress the cleaning work on the western outfall pipeline at a faster rate.
