The County of Brant is undergoing a study to evaluate various design alternatives and treatment technologies to effectively treat the future wastewater flows from the community of Paris. The study involves an environmental inventory/impact study, archaeological investigations, and a cultural heritage investigation.

Public engagement is an important part of this study. Our public engagement plan includes a Public Information Meeting, newspaper advertisements, social media posts, postings on Engage Brant and the County’s website, and updates to Council throughout the completion of the study.

    What is the proposed timeliness for shovels in the ground

    Trevor asked 6 months ago

    Thank you for your question. Following the public meeting, the County will complete the Environmental Servicing Report (ESR) and expects to complete the Class Environmental Assessment (Class EA) process during the Spring of 2025. We intend to begin design immediately upon completion of the Class EA, and expect that the design process will take approximately 2 years, following which, construction will be ready to begin.

    Thanks,

    The Phase 1A stress test will be the first task in detailed design. We intend to begin detailed design by the end of 2025, and anticipate that the stress test will be completed during the first quarter of 2026.

    Hi Samantha-Liegh,

    The Paris wastewater treatment plant (WWTP) was first constructed on this site in 1963, when the surrounding area was undeveloped. The decision to upgrade and expand the WWTP at its current site has been long decided as the favourable path for expansion. In 1981, the WWTP was expanded at the current site from an initial rated capacity of ~2,500 m3/day to 5,796 m3/day, and again in 2005 the plant was expanded on its current site to a capacity of 7,056 m3/day. The County purchased the land adjacent to the Paris WWTP in March 2000 for the purposes of potential future expansion, and as such all upgrades to the wastewater conveyance network have been planned such that all sewers will continue to route to the existing WWTP site. Alternative WWTP locations were discussed during the Master Plan process but were quickly ruled out for several reasons including the costs & construction disruption associated with the redesign and rerouting of Paris’ sewer network, pump stations and forcemains, the costs & regulatory approvals required for acquiring new land for a new WWTP, the regulatory requirements of obtaining MECP approval for a new outfall, and the costs associated with construction of a brand new WWTP facility sized for the 2051 growth horizon.

    An Air & Noise permit was required for the construction of the new leachate offloading system on-site, which included air monitoring be done as part of the application process. This monitoring indicated that the air emissions from the WWTP for ammonia and total reduced sulphur, two highly odorous parameters, were compliant with Ontario regulations. Additional air quality monitoring will be completed during the detailed design of the WWTP as a part of the WWTP Air and Noise permit application. An Environmental Conditions Report was completed as a part of this Class EA and will be published on EngageBrant to review once the Class EA has finished.

    The exact distance between the sidewalk and the nearest WWTP building cannot be determined from conceptual design. The layouts presented as part of the Class EA are conceptual in nature and subject to change during detailed design. However, the County plans to keep the existing trees along Race Street to continue to provide a barrier and obscure the view of the WWTP from the neighbourhood.

    All of the background studies for the current project (archaeology, soils, environmental conditions, assimilative capacity analysis, etc) will be finalized and included in the Environmental Study Report for this Class EA and will be posted on this Engage Brant page for public review in the very near future. This final report will also be posted on this page. Add your email to the Stay Informed box on this page and click ‘Subscribe', to be notified of project updates as they are available.

    Sven asked about 2 years ago

    Thank you for your comments and your interest in this project. The treatment plant is capable of remaining in operation during high water levels in the river. If water levels are high enough, treated water must be pumped to the river rather than flowing by gravity. The treatment plant will likely be expanded into the natural area to the north of the current plant and will also be designed to remain in operation during flood conditions. The upgraded plant will also be designed to handle peak flows related to weather events, with partial plant by-passes being a very rare occurrence. The upgraded plant will include some small control buildings but the majority of new works will be in-ground tanks. We are working towards a public meeting that will be held in the fall of 2023. Conceptual designs will be presented and we will be interested in receiving feedback from the community. Again, thanks for your questions.

    Thank you for your question. The Paris wastewater treatment plant will continue to receive liquid wastewater from other facilities but the conceptual design of the upgraded facility will evaluate various layouts that will reduce the number of trucks having to back into the treatment facility.

    Thank you for your question. Mitigating odours will be included as an important criteria for evaluating different alternatives for the upgraded facility. The facility will continue to produce occasional nuisance odours in the vicinity of the plant but any new plant layouts and designs will consider approaches to reduce negative impacts to neighboring properties.

    Thanks so much for your comprehensive set of questions. We will most certainly address all of them as we go through this Class EA project. Through the initial public contact we have received a number of questions from the local community and we certainly do have an understanding of these local concerns and what we will need to address during this Class EA. At this time we are conducting background studies on potential archaeological and environmental impacts to the site area and conducting an effluent assimilative capacity study that will eventually lead to effluent limits for discharge to the river. Until these are completed we are not in a position to provide you with answers to your questions. Be assured that when we complete the background studies they will be shared with all interested parties and agencies and we will do our best to address all of your concerns. Our goal is to complete all of the background studies prior to the first Public Information Centre. We anticipate this to be in early fall but will depend on completion of studies, some of which may be seasonally dependent. We hope to be in a position to specifically address all of the questions we have received to date prior to the first Public Information Centre in order to make that public contact as productive as possible. Again, thank you so much for your input and we look forward to engaging with you as we try to find the best wastewater servicing solution for our community.

    Elizabeth asked about 3 years ago

    Thank you for your questions. The County completed the Paris Master Servicing Plan in 2020 and it considered various alternatives for wastewater treatment, including replacing the existing facility at a new location, or building another facility in a different location to handle the increased flows. The study ultimately confirmed that the preferred solution for wastewater treatment was to expand the existing plant to handle future flows to the design horizon of 2051. The current project is to determine the preferred design concept for expanding the existing facility in the same location. The facility will be expanded to handle future flows to the design year 2051, but flows will only increase incrementally each year. Truck traffic isn’t expected to dramatically increase for the foreseeable future. The expansion will require some of the forested lands to the north of the facility, but we plan to only remove trees where necessary.
