Larchmont Area Sanitary Sewer Improvements (LASSI) Program
--Hanover Pump Station Construction Work to Begin--
HRSD, your regional wastewater treatment utility, is starting a project in your neighborhood to replace the existing HRSD Hanover Avenue Pump Station that is nearing the end of its useful life. This replacement project will improve the sewer system’s performance and ensure continued, reliable sewer service in the future. This work should take place primarily between the hours of 7 a.m. to 5 p.m., Monday – Friday.
Construction Update
- Beginning as early as Monday, September 22nd, construction will begin at the new pump station site at 933 Hanover Avenue.
- The initial work will consist of the mobilization of excavators and trench systems at the pump station site.
- This will be followed by the installation of dewatering systems at the pump station site to remove groundwater to create a dry and safe excavation environment.
- Finally, excavation and installation of the trench system will begin to dig out the area where the pump station wet well will be placed.
- This work will take place during the daytime and within the right-of-way. Nighttime work is not anticipated, but if it needs to occur, the contractor will notify you in advance.
- Work at the Hanover Pump Station site is anticipated to be completed within 2 years. Due to the nature of construction, work is weather- and situation-dependent and dates are subject to change or be extended.
The following conditions can be expected during construction:
- Your water and sewer service will not be disrupted.
- Through traffic will be detoured around active construction zones, but residents will still be able to access their homes. On-street parking will be closed in active pipeline construction zones, which is not expected to occur until later in the project.
- Vibration, Noise, and Dust Control:
- Vibration monitors will be located onsite and near construction areas to minimize disruption. Alerts are provided to the contractor if the vibrations reach a particular level, and work will be stopped if these vibrations exceed federally established levels that may cause damage to residential structures.
- Noise can be expected from excavation, backup alarms, diesel generators, motors, sheet pile driving, and other work.
- Dust control measures, such as temporary paving, frequent road cleaning, and/or application of water, will be enacted to reduce dust from becoming airborne.
- Construction work sites will be fenced in to protect from entry, and warning signs will be placed around pipeline work.
- Roadways and rights-of-way will be restored to their pre-construction structure and materials.
- Construction update notices will be distributed to those in the affected areas throughout the project to provide updates of upcoming work. These notices will also be posted on the project webpage and NextDoor.
While our project team works diligently to minimize impacts, you may notice increased noise and traffic, along with the people and heavy equipment (with back-up safety alarms) associated with construction. Please take care when traveling around the construction area and for your safety, do not enter the site. Due to the nature of construction, work is weather and situation dependent, and dates are subject to change.
