Eastern Engineering is committed to helping communities expand, upgrade, and protect access to safe, reliable drinking water. We frequently partner with towns to extend public water service to areas where residents rely on private wells, and to rehabilitate aging infrastructure that no longer meets modern standards.

Our team provides expert design services for projects ranging from targeted system extensions to the development of entirely new water utilities. We also support municipalities in addressing emerging contaminants such as PFAS, offering rehabilitation solutions that include treatment system upgrades and the integration of advanced filtration technologies. Whether you’re expanding service, replacing outdated components, or tackling water quality concerns, Eastern Engineering delivers cost-effective, regulatory-compliant solutions tailored to your community’s needs.

Our team has extensive experience with sewer rehabilitation projects, including pipe lining, point repairs, and manhole restoration, all aimed at extending system life and reducing inflow and infiltration. We also specialize in the design and rehabilitation of sewer lift stations to support new development and improve overall system performance.

From planning through permitting and construction, Eastern Engineering delivers reliable, cost-effective solutions tailored to your community’s needs.

In areas without access to a municipal sewer system, a properly designed onsite septic system is essential. Eastern Engineering specializes in designing a wide range of engineered septic solutions tailored to meet the your specific needs. We provide the most economical and effective system for your home or business. Whether you require a conventional septic tank, STEP (Septic Tank Effluent Pump) system, or residential grinder pump station, Eastern Engineering offers comprehensive, turnkey services to help streamline your septic system approval and installation process from initial concept and soil evaluation through permitting and construction.

From initial feasibility studies and permitting to final construction plans and inspections, Eastern Engineering has the experience you need to streamline project delivery and ensure long-term performance.
