If it isn’t sustainable, it isn’t good design.

Prein&Newhof’s commitment to sustainability began more than 45 years ago and is a hallmark of our work — thinking green is nothing new to us.

What do we mean by ‘sustainability’?

Projects that: work with the environment, reduce energy use and waste, and restore our natural resources and are all are done in a financially-responsible way.

1. Lower Ecological Impact

Smarter designs that fit seamlessly into our ecosystems:

  • Stormwater systems that protect local rivers and streams from excessive, polluted runoff through porous pavement, rain gardens, stormwater treatment, and other methods.
  • Drinking water wells that can provide long-term supply without impacting other wells or environmental resources.
  • No-dig technologies (like directional drilling and pipe relining) that decrease erosion, equipment fuel use, traffic delays, and construction waste.
  • Green biofiltration systems that minimize wastewater odor without the use of toxic chemicals.
  • Trails and sidewalks that help reduce pollution and improve public health.
  • Roads, pipes, and buildings made from recycled materials.



2. Energy Recovery & Conservation

Intelligent systems that do more with less:

  • Well-planned water and sewer systems that require a minimal amount of pumping.
  • Treatment plants and pump stations minimize energy use with high-efficiency pumps, variable-speed equipment, and energy-recovery techniques.
  • Structures that use or contribute to the production of alternative energy sources.
3. Environmental Renewal

Creative engineering that restores and improves communities:

  • Identifying and cleaning up contaminated groundwater.
  • Using state-of-the art technologies that turn sewage into extremely clean water — in some cases, five times cleaner than required by the State.
  • Re-using blighted urban areas through brownfield redevelopment, saving precious underdeveloped land.
  • Converting closed landfills into usable public spaces.
4. Financially-Sustainable Improvements

Smarter spending through big-picture planning:

  • Long-term planning that anticipates a community’s needs and helps them choose the best (and most efficient) time to make improvements, often by combining projects.
  • Projects designed for longevity and minimal maintenance using a practice referred to as “life-cycle cost management.”
  • Well-planned sewer systems that use more gravity sewer, fewer pumping stations, and less energy. (Some of these projects reduce energy use so much, they pay for themselves in a few years.)
  • Asset management plans for communities to prolong the life and make the most efficient use of their paved roads.
  • Proper public utility rate structures that enable communities to save for future needs.
