Project overview

Project description

The City of Ottawa is currently constructing the upgrades to the Carp Water Treatment Facility. While the Provincial drinking water standards are consistently being met, the work being completed will improve the water source quality by installing a Granular Activated Carbon filtration system as well as to complete electrical upgrades to the existing water treatment facility.

Project timing

Construction completion: summer 2023


Project funds approved to date are $6.85 million.


Accessibility is an important consideration for the City of Ottawa. The City makes every effort to provide access through and around construction sites.

Construction start notice (October 2018)

Beginning in October 2018, the City of Ottawa will begin work in your neighbourhood. This work is being completed to resolve taste and odour issues in the source water before treatment, as well as to complete electrical upgrades to the existing water treatment facility.

Who: The City of Ottawa has hired the contractor, Thomas Fuller Construction, to complete the work.

Why: The source water currently pumped from the wells at the Carp Water Treatment Facility contains concentrations of sulphur/organic compounds. While the provincial drinking water standards are consistently being met, treated water from the facility has objectionable taste and odour believed to be formed when chlorine reacts with the sulphur/organic compounds. In 2014, the City of Ottawa completed a pilot study and functional design to evaluate the effectiveness of filtering the water through a granular activated carbon filter to resolve taste and odour issues by removing dissolved organic carbon and hydrogen sulphide present in the source water before water treatment (chlorination). Testing completed during the study confirmed that water treated with granular activated carbon, prior to chlorination, tasted significantly better than that treated only with chlorine.

What: Work will involve the construction of a new 9 metre tall, 15 metre long and 9 metre wide building to house the proposed granular activated carbon filtration system sized for the current capacity of the well pumps, with full redundancy. The new structure will be constructed at the south-west corner of the Carp Water Treatment Facility property, located at 135 Salisbury Street.  Work will also involve the construction of a number of electrical, instrumentation and controls upgrades within the existing facility to improve reliability of the water production system for the village of Carp.

Where: Carp Water Treatment Facility site, 135 Salisbury Street, Carp, Ontario.

When: Construction activities are currently scheduled to begin mid-October 2018.  The work is expected to be completed January 2020. The City of Ottawa Noise By-law (2017-255) allows construction activity to occur weekdays between 7 am and 10 pm. On Saturdays, work is permitted between 7 am and 10 pm while Sunday and statutory holiday work is allowed between 9 am and 10 pm.


Accessibility is an important consideration for the City. If you require special accommodations, please contact the undersigned. Provisions in the contract have been made in order to ensure Para Transpo vehicles are able to access the apartment buildings within the limits of this project.

Construction disruptions

The contractor is assuming full responsibility for the construction work until the work is entirely complete. The contractor will take every precaution necessary to minimize interruptions to the everyday life of your family and/or operation of your business, but as you can appreciate, there may be some inconvenience during the course of the work, such as delays and traffic detours when travelling near the construction zone, noise, dust and vibration. We would like to thank you in advance for your patience and co-operation.

On-street parking and traffic

During construction, on-street parking may be prohibited along Salisbury Street within the vicinity of the Water Treatment Facility. The contractor is responsible for the provision of a safe and accessible path of travel for all pedestrian through and/or around the construction site at all times.

Pre-construction survey

The Contractor is required by the City to carry liability insurance before any work may proceed. You may be asked by the contractor’s insurance agent for permission to survey your property before the work commences, as contractors typically conduct pre-construction inspections to document existing conditions for their own purposes. It is to your benefit to allow the inspection to be conducted on your property, as it may assist with establishing the impact, if any, that construction has had at your property after work is complete. In addition, you may wish to complete your own survey of pre-construction conditions on your property. Your survey should include photographs.
