Sustainability

 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, restore our natural resources, and 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.
