Project Description

At beginning stages of the project, M2 Engineering spent time understanding the existing water treatment plant in Joussard. In our review we found that the system was lacking redundancy, multi-barrier protection, and robustness within their treatment system. The system was running with a single intake and single operating trains with no backup systems.

The single intake was of particular concern as this is the only means of water supply to the water treatment plant. If the line or intake failed in any way, the facility would not be able to produce drinking water for the community. A similar philosophy applies to single operating trains.

In addition to resiliency, our design focused on providing redundancy and robustness to the facility. With this objective, we included:

  • Upgrades to the existing intake and the addition of a new redundant intake

  • Two trains of conventional treatment

  • Three trains of reverse osmosis (RO) membranes

  • Duty/standby pumping systems

  • Backup power

The redundancy of the treatment system is beneficial in more than one way. It is beneficial from a repair and maintenance perspective but also beneficial for operator flexibility. There are significant seasonal fluctuations in water demands and the multiple trains allow the facility to operate either one or two trains at a time. This flexibility allows the facility to operate more efficiently, and routine maintenance and cleaning can be scheduled during low demand seasons.
