2.2 WET WEATHER SYSTEM PLANNING
Halifax Water faces a number challenges associated with wet weather impacts on the
sanitary and combined wastewater systems. In response they have created a range of
programs for I/I reduction, improved flow control at WWTFs and pumping stations and
the offset of growth impacts on overflows as proposed in the RWWFP. There is need to
consolidate these initiatives into a Wet Weather System Plan. The Wet Weather System
Plan will include the following components:
• Identification of wet weather related sanitary and combined system drivers and
development of wet weather management objectives supported by LOS statements
and metrics.
• Review and analysis of existing information and data and identification/confirmation
of gaps.
