PROJECT DESCRIPTION:
The City of St. John’s, the City of Mount Pearl and the Town of
Paradise have a combined population of 130,000 people. Municipal
wastewater from these municipalities is currently discharged,
untreated, into St. John’s Harbour.
The purpose of the multi-phased St. John’s Harbour Clean-up
project is to provide treatment of the wastewater before
discharging to the Harbour.
Phase 1 of the project is completed and included:
• collection, redirecting and screening sewage flows from the
Waterford Valley drainage basin
• a diffused outfall on the south side of the Harbour
• construction of the pumping station on Southside Road
Phase 2 of the project includes:
• construction of the primary treatment plant on Southside Road
• expansion of the pumping station
• construction of the harbour interceptor sewer from Temperance
Street to the Southside Road treatment plant
• additions to the existing diffused outfall

ENVIRONMENTAL ASSESSMENT
As required by the Canadian Environmental Assessment Act, an
environmental assessment of the harbour project was carried out in

Sketch Unveiled
On June 4, 2005, the first visual image of the primary
treatment plant operation was unveiled at City Hall. The Hon. John
Godfrey, Minister of Stage (Infrastructure and Communications),
the Hon. Jack Byrne, Minister of Municipal Affairs and City of St.
John’s Mayor Andy Wells joined architect Phillip Pratt in
unveiling the sketch of the Riverhead Wastewaster Treatment
Facility.

sketch.
Riverhead Wastewater Treatment Facility
Riverhead was an area in St. John’s that extended along
the Waterford River from Mill Bridge to the mouth of St. John’s
harbour. The area once contained notable structures such as St.
Mary’s Church, the Riverheard Hospital (in the 1800's), Long’s
Bridge and a multitude of mercantile premises. Merchants with
premises on the Riverhead gradually filled in the Waterford River
to give more land for their operations. The construction of the
Railway Station in 1902-03 completed the fill-in.
The City of St.
John’s felt that it was important for the name of the new
wastewater treatment facility to reflect the history of this area.
St. John’s City Council approved the name for the new treatment
facility at the special meeting of Council on March 21, 2005.
Construction
700,000 cubic meters of material was
removed from the construction site. Construction of the plant is
underway and is scheduled for completion in the fall of 2008.
A traffic signal system has been installed and activated at the
intersection of Pitts Memorial Drive and the Southside excavation
access road. This system will permit the safe and organized
movement of construction and public traffic.

The Riverhead Wastewater Treatment Facility on Southside Road is over 90% complete as of the end of 2008.
The facility is expected to be operational by summer 2009.
Harbour Interceptor Sewer
The Harbour Interceptor Sewer is 2 km of 1650mm (5 foot ) diameter trunk sanitary sewer
pipe that is being installed to collect sewage that currently enters the harbour at Temperance Street,
Prescott Street and other minor outfalls along Harbour Drive.
Sewage will be redirected to the Riverhead Wastewater Treatment
Facility currently under construction on Southside Road.
As of December 2008 the Harbour Interceptor Sewer is complete from
Ayres Cove East to Temperance Street and from Waldegrave Street to
Bishops Cove along Harbour Drive.
2009 will see the construction continuing on Water Street West
from Job's Bridge to Waldegrave Street and on Harbour Drive from
Bishops Cove to Ayres Cove as well as in Bishops Cove and Beck's Cove.
2009 will also see the construction of combined sewer overflow chamber Beck's Cove, Prescott Street, and Temperance Street.
It's anticipated that all work on the HIS will be completed by the end of 2009.
The City is most grateful for the patience and good will of it constituents and visitors in bearing with inconvenience of constructing this sewer.

Funding
Funding of $93 million has been established for the capital cost of Phase 2 of the multi-phase St. John’s Clean-Up Project. The federal and provincial governments are each contributing $31 million, while the remaining $31 million is being provided in a proportionate share by the City of St. John’s, the City of Mount Pearl and the Town of Paradise. Operating costs will be shared by the municipalities.
The cost of the project has increased by $44.4 million. This increase in cost is attributed to several factors since the original estimate of $93 million for the St. John’s Harbour Clean-Up Project was developed in 1999.
(I) An overall increase in industry construction costs since 1999. The construction cost for a number of areas in Canada has risen by as much as 33% since 1999.
(ii) St. John’s construction labour rates have also risen in recent years by approximately 26%.
(iii) Cost of steel has increased by 46% since 1999.
(iv) The detailed design has provided accurate information on various components of the project, i.e. mechanical and electrical requirements , instrumentation, mechanical , process power equipment, etc. This detailed design has resulted in modifications to the original concepts and layout used in the preliminary cost estimates.
