Water Quality Master Plan

Trigon was a major sub-consultant (with 35% of the project) for this project that involved both of the Sewerage and Water Board of New Orleans’ (S&WB) major water treatment plants – the Carrollton Water Treatment Plant (WTP) on the East Bank of the Mississippi River as well as the Algiers WTP on the West Bank.

The project generally consisted of performing an assessment of both the Carrollton WTP and the Algiers WTP to determine physical, operational and process conditions of all infrastructure at the plants. Based on the assessments, the current status was documented and a forecast of issues to be addressed was developed, including a prioritized list of short- and long-term needs required to address reliability and redundancy.

Trigon staff served in roles of technical assessors (for process, mechanical and structural items) during the field assessments and developed rehabilitation recommendations and associated cost estimates and summary reports. This formed the basis to develop short- and long-term capital improvement programs for the S&WB.
The field assessments were completed in the Fall of 2014 and the rehabilitation recommendations and associated cost estimates were finalized in early 2015.
