ADI Limited has won a contract to design and manage the re-
routing of Coke Ovens Brook, the first step in cleaning up the
Coke Ovens property.
The Fredericton-based engineering firm, which has maintained
offices in Sydney since 1981, will complete detailed engineering
plans for the job, prepare tender packages for contracting firms,
and manage the construction project.
Barring unforeseen regulatory difficulties, construction will
begin in the summer of 2005.
In its current alignment, Coke Ovens Brook picks up contaminated
groundwater as it meanders through some of the most heavily
polluted parts of the Coke Ovens property.
Last summer, an engineering report by Dillon Consulting Ltd.
recommended re-routing the brook along two branches that would
flow through less contaminated areas. Moving the brook will also
permit more thorough cleanup of the stream bed, where
contaminants accumulated during a century of coke production.
ADI will use a total of 21 engineering and support staff on the
project, 15 of them based in Sydney. The engineering design and
management contract is worth $578,000.
"After many years of study and talk," said Richard Morykot, the
Sydney Tar Ponds Agency engineer in charge of the project, "this
is the first concrete step in cleaning up contamination on the
The newly realigned brook will have two branches:
- The south branch will start at the outflow from the MAID Pond,
behind the Schwartz building on Vulcan Avenue. It will run along
the southern boundary of the Coke Ovens site, parallel to Vulcan
Avenue, through an area known as Mullin's Bank. Near the western
boundary of the site, the brook will merge with Cagney Brook and
run north, parallel to Victoria Road, and then follow the
existing channel under the Victoria Road overpass.
- The north branch will run along the Whitney Pier side of the
Sydney Coal Railway track and the SPAR road, picking up flows
from several smaller brooks along the way. It will cross under
the tracks and the Spar Road at a point just east of Lingan Road,
and follow the rail spur through the Coke Ovens site to join the
south branch at the Victoria Road overpass.
Part of the relocated south branch will be piped underground, and
portions of both branches will be lined with synthetic material
or clay to prevent recontamination.
Engineering work continues on three other projects that have been
advanced to prevent environmental damage while the cleanup
undergoes mandatory environmental assessment. The projects
- the construction of a coffer dam at Battery Point,
- the cleanup of the cooling pond at the southwest corner of the Sysco
- the relocation of the Victoria Road water main.
