The City of Portsmouth is required under Provision IV.d of the Second Modification of Consent Decree 09-cv-283-PB to extend sewer service to the Sagamore Avenue area and Walker’s Bungalow Road area (these areas include Sagamore Avenue, Walker Bungalow Road, Shaw Road, Cliff Road, Little Harbor Road, Sagamore Grove, and Wentworth House Road). The purpose of this project is to meet the requirements of this consent decree by constructing a sewer system to serve the residential, commercial, and recreational properties that reside in the project area. As part of the process the project requires permits from the New Hampshire Departments of Environmental Services (NHDES) Standard Dredge and Fill Permit, NHDES Shoreland Protection Permit, NHDES Alternation of Terrain Permit, Construction General Permit, NHDOT Road opening permit and a Remediation General Permit along with local permitting requirements.
The NHDES Environmental Review has determined a Finding of "No Significant Impact" for the proposed project and received no comments during the public input review that ended June 25, 2021.
Please continue to direct comments or questions about the proposed sewer connections to Zachary Cronin, Assistant City Engineer, at firstname.lastname@example.org or 603-610-7304.
April 13, 2021 Update
The Planning Board approved the Conditional Use Permit. We have sent the plan set to NHDOT for their review. We have also sent the 90% specifications to NHDES for their review.
March 26, 2021 Update
As part of the permitting process, DPW presented the project drawings for approval of the City's Conditional Use Permit and Wetlands Permit to the Planning Board and the Conservation Commission.
The Department of Public Works continues to make progress on the Sewer Extension Project and now offers residents draft drawings of the project, including the work on private property. [click here]. The properties included on this sewer connection plan are owned by those who have held individual site meetings with the project consultant, Wright-Pierce. The drawings are drafts, subject to change based on homeowner request. These drawings do not require or obligate that anyone joins the project. This is simply a step in the process needed to keep the project moving forward.
As part of the permitting process, DPW presented the New Hampshire Department of Environmental Services Wetland Permit [click here] and the City’s Conditional Use Permit for the Sagamore Avenue Sewer Extension Project to the Conservation Commission on Wednesday March 10

As part of the Sagamore Avenue Sewer Extension Project, borings are needed to collect data about the soils and bedrock in the project area. The first phase of borings was completed in the spring of 2020; and this work will complete the boring data collection. Work is scheduled to take place Monday, February 22 through Friday, February 26, 8 am to 3:30 pm, weather permitting. The work area includes the zone announced in January: Walker Bungalow Road at the Shaw Road intersection, and sections of Sagamore Avenue and Wentworth House Road. The work will take place on one side of the road, leaving one lane for traffic; but some delays may be expected.
February 8, 2021 Update: Reviewing draft wetlands permit.
See the schematic below for the current limits of the project that include portions of Sagamore Ave, Shaw Road, Cliff Road, Walker Bungalow Road, Sagamore Grove and Wentworth House Road to the Town of Rye line. This project was incorporated into the Consent Decree in September 2016 as a supplemental environmental project as part of a Consent Decree modification to extend the time for construction of the City’s Peirce Island Wastewater Treatment Facility.
The goal of this work is to extend public sewer service in an area with existing septic systems. This will provide an outlet for failed septic systems or for property owners interested in connecting to a public sewer system. This will reduce the bacterial load (in the case of failed septic systems) and reduce nitrogen discharged to Sagamore Creek, which discharges to the Great Bay Estuary.
The proposed system is a low pressure sewer system. This type of system reduces construction costs by using small diameter pipes that can be installed at shallower depths than conventional sewer system mains. This system requires that each property has an ejector pump that discharges the sewerage into the small diameter main. A property with a functioning septic system will not be required to connect to the new sewer. Once the new sewer system is constructed, however, a property whose septic system fails will be required to connect.
It is anticipated that this project will begin construction in the Spring of 2021.
MEETINGS AND PRESENTATIONS
Please note that due to the progression of the project, there may be contradictory project details within the presentations below.
• Authorize the final permitting design and bidding necessary to install public sewer mains and private components to the full project limits (91 connections).
• Direct that the bid document be structured so as to allow for the base bid to include the installation of all public sewer mains and the bid alternates to consist of all the private property work.
