346-382 - District of Barrier Cluster C WWTP

The Vendor shall provide the following services
1.    Proprietary wastewater treatment process design, complete with design drawings sealed by an engineer registered in BC;
2.    Specific proprietary process equipment and appurtenances (pumps, valves, instruments, etc);
3.    Commissioning support to construction contractor, and;
4.    Process performance guarantee.
The design of the WWTP will have the following general characteristics:
•    Bioreactors (minimum of two trains) with blowers (minimum of two)
•    Effluent filtration (minimum of two trains)
•    Improvements to the existing aerobic digester, including replacement blower
•    Process equipment including pumps, valves, blowers and aeration systems.
Without prejudice to the required effluent criteria, acceptable treatment technologies are;
•    Sequential batch reactor with cloth media filtration
•    Membrane bioreactor
District staff have expressed a preference for the sequential batch reactor with cloth media filtration technology. This is based on concerns over the long-term costs of regular membrane replacement. Nevertheless, the performance criteria described in this specification must be consistently achieved.
The Drawings illustrate the expected scope of supply and desired layout.
