14Waste water treatment plants
1
The construction of a waste water treatment plant is a significant infrastructure project if—
a
the treatment plant is in Wales or the Welsh marine area, and
b
the treatment plant (when constructed) is expected to have a capacity exceeding a population equivalent of 500,000.
2
The construction of infrastructure for the transfer or storage of waste water is a significant infrastructure project if—
a
the infrastructure is in Wales or the Welsh marine area,
b
the main purpose of the infrastructure is—
i
the transfer of waste water for treatment, or
ii
the storage of waste water prior to treatment,
or both, and
c
the infrastructure is expected to have a capacity for the storage of waste water exceeding 350,000 cubic metres.
3
The alteration of a waste water treatment plant is a significant infrastructure project if—
a
the plant is in Wales or the Welsh marine area, and
b
the effect of the alteration is expected to be to increase by more than a population equivalent of 500,000 the capacity of the plant.
