Recognizing shared services as an effective way of controlling costs and keeping taxes stable, Lambertville is one of the leaders, among New Jersey municipalities, in pursuing and realizing shared service agreements with neighboring communities and other government entities. For example, the City enlisted neighboring communities such as West Amwell, area public schools and the Lambertville Sewerage Authority in the successful South Hunterdon Regional Energy Cooperative (SHREC), that continues to produce savings in energy costs and curb greenhouse gases, through implementing energy efficiencies and using solar power. Similarly, Lambertville has saved money on the costs of its Construction Office through a shared services agreement with Frenchtown. Generally speaking, shared service agreements produce savings because economies of scale are realized.
