Our Projects - Napanee, Ont.

Receiving Stream Impact Assessment Study:

Riggs Engineering was retained by Genivar to assess receiving stream impact due to waste water treatment plant discharge.

Riggs Engineering developed a 3D hydrodynamic model of the Napanee River from the downtown to its outlet at the Bay of Quinte in order to quantify the impact of increased effluent discharge on the existing river. A hydrodynamic model was necessary as simpler techniques proved to be inadequate in estimating mixing and dilution characteristics of the receiving stream.

The 3D numerical model uses Environmental Fluid Dynamics Code (EFDC) as part of the receiving stream study. Effects of proposed discharges were quantified, and summarized according to current Ministry of Environment guidelines.
