Management
of All Site Produced Waters and Wastes
Storm Water, Ground Water, Leachates,
Process Effluents and Solid Residues
In some areas of the world, water is in short supply and
yet the volume of run-off generated by heavy rainstorms is
a major problem, not only causing flooding and erosion, but
flushing contaminants from industrial sites onto neighbouring
ground, into water courses and into ground water. These effects
are in addition to the water and ground contamination associated
with fall out from dust and fume emissions.
In South Africa, RPA personnel were engaged to identify the
Best Practicable Environmental Option (BPEO) for the approximately
300 hectare production, raw materials and waste stockpile
areas of a large stainless steel and ferro-chrome production
facility as it went through a major production expansion.
This site is now the largest integrated stainless steel and
ferro-chrome manufacturer in the world. The consultancy work
has ranged from identifying the overall holistic process concepts
in conformity with the BPEO principles, through to economic
assessments associated with each component section, outline
and detailed designs, construction supervision, commissioning
and ongoing process support. The list of consultancy services
is long and spanned a continuous nine year period. The list
included the following:
- Modelled storm events and run off characteristics to predict
run-off volumes;
- Assessed the capacity of existing storm water infrastructure;
- Designed and implemented measures to separate the clean
from the contaminated storm water run-off thereby ensuring
that up to 300,000m3/day of rainwater remained clean;
- Specified new drainage and contaminated water storage
capacity;
- Developed a storm and ground water management system and
an effluent containment, treatment and recycling system;
