Hall/Parsons Road Local Area (Sewer) Service Project
Update
The final report for the Hall Road Neighbourhood Hydrogeological Analysis is now complete.
The report confirms that the necessary engineering requirements and construction methods are appropriate to construct sanitary works with minimal or no disturbance to existing groundwater flow patterns in the Hall Road area.
Although the City has not been able to acquire grant funding for this project to date, the City will follow through with an application at the earliest funding opportunity.

Background
In 2006, the City of Kelowna consulted with residents in planning for future sanitary sewer servicing in the Hall Road neighbourhood. As result, 64 per cent of the property owners responded in favour of participating, if the City could obtain Provincial and/or Federal funding.
The planning of this project is based upon a 2000 pre-design study which included preliminary sewer system routing and cost estimates. Since the completion of this report, residents have raised questions regarding constructibility of the improvements and potential impact to the groundwater aquifers, surface ponds, wetlands and private wells. In response, the City commissioned a Hydrogeological study to answer some of those questions.
The City has commissioned AECOM and SLR Consulting Ltd. to conduct a hydrogeological analysis in sufficient detail so as to determine the appropriate engineering efforts necessary to undertake and complete the construction of sanitary sewer works with minimal or no disturbance to existing groundwater flow patterns in the Hall Road neighbourhood. Scope of analysis included:
- The installation of 12 groundwater monitoring wells to determine the elevation and depth to groundwater across the study area
- Hydraulic conductivity testing in the soil adjacent to the wells to measure how easily groundwater will flow through the soil
- Topography and groundwater flow
- Surficial geology to determine types of soil that exists in the study area, (i.e, clay, silt, sand).
Preliminary findings of the hydrogeological analysis indicates that the proposed routing and pipe depths will not be significantly affected by the localized shallow groundwater. The report will recommend specific engineering measures that will need to be implemented during construction, where shallow groundwater is encountered and where seasonal groundwater is expected. Phasing of the project will also be necessary to avoid peak groundwater periods and minimize and trench de-watering. Impact to project cost estimates, resulting from these recommendations are expected to minimal (e.g., less than 5 per cent).
Next Steps
Potential sewer servicing in the area will only be considered should a Municipal Infrastructure Grant opportunity becomes available as agreed upon by Hall Road residents in 2008. See background for details.
