Echowater Project Site Preparation Project

The scope of work for the Site Preparation (Site Prep) Project included installation of:

  • New and modified roadways
  • Two new high security entrance gate facilities
  • New stormwater infrastructure, including several new stormwater detention basins and piping
  • Two large contractor logistics complexes including office and conference trailers, contractor parking and material and equipment laydown areas (totaling approximately 20 acres) for accommodating multi-year, multi-contractor projects

The Site Prep project is one of the most complex of all the EchoWater Projects because it deals not just with many different utilities. The Site Prep project required coordination with all the new facilities designers (as well as maintenance, operations and the PMO) to ensure that the infrastructure meets their future facility needs. Each facility designer was at a different point in their own design process so it often took predictive modeling scenarios to anticipate the facility’s water, sewer, storm drain or power requirements because designs were incomplete.  The Site Prep team had to plan for multiple different road closures and reconfigurations to accommodate construction equipment traffic, contractor vehicles, and plant staff vehicles all in close proximity.

Stormwater handling required many sequencing steps to ensure that winter rains would not unduly impact the site, whilst new storm drains were being installed. Several temporary and permanent storm drain detention basins were planned, designed, and constructed on a tight schedule dictated by seasonal weather and the construction activity and regular plant operations (which included Sacramento Regional WWTP’s harvesting activities).
