We can help clients reduce potential impact of public improvement projects by reviewing plans at an early stage, analyzing conflicts, innovating designs, and negotiating with affected stakeholders to reduce unnecessary asset relocation.

We offer expertise in the following areas:

  • Urban and metropolitan main installation design
  • Distribution inspection

  • Flow modeling
  • Meter/Regulator stations

Our experts include professionals well versed in federal, state, and local regulations to help ensure the compliance of your system and the safety of the surrounding public. Working with our internal Integrity team, we take care to effectively identify and analyze potential risk so clients may better manage and mitigate risk relating to their assets and business operations.
