Plans to service new developments

The City is continuing to plan sanitary service to Quance Development lands to the east of the City.

Yorkton Council heard an update on the plan at its regular meeting Monday.

"Engineering Services approached Associated Engineering to develop a sanitary servicing plan for the commercial and residential development properties east of Husky Road, on the north side of Highway 10. A preliminary report was prepared earlier this year and the conclusions outlined to Council. The report outlined several options ranging from temporary solutions for immediate needs to trunk sewers servicing large portions of land to the southeast, east and northeast for more than twenty-five years," detailed a report circulated at the meeting Monday.

"Follow up work occurred to determine if the temporary servicing options were viable. This required flow monitoring in order to determine where on the existing system, additional flow could be added without the risk of flooding homes and businesses. The flow monitoring that was performed identified that the existing system was very limited with respect to adding additional flow. Two primary locations to tie into included Darlington Street and Broadway Street. Darlington Street was found to have approximately 26 L/sec capacity available and Broadway Street was estimated to have approximately 15 L/sec available capacity.

"Assuming standard flow quantities, approximately 40 ha (100 acres) and 20 ha (50 acres), respectively, could be serviced by these two primary tie in points. It became apparent from this monitoring that a temporary solution for the entire development area was not feasible and that a new trunk system would be required to address the future developments."

A new sanitary trunk line is central to the work,

When all the information was brought together, it was evident that the city had to view sanitary servicing in the following manner:

Strengthen the existing system by creating redundancy;

Improve the existing capacity within the Dracup Avenue trunk main; and,

Service areas outside of the existing system by a cost effective method.

The city has only a single outfall to the wastewater treatment plant. It would be difficult for the city to undertake maintenance of this outfall without an alternative route to the treatment plant. The outfall is one of the oldest components of the sanitary system. The need to twin it has been identified by Environmental Services. The proposed system will enable the city to twin this outfall in the next three to five years.

Whatever shape the project takes, it will come at a major cost.

"The estimated capital cost for the first phase is $9.26 million. Completing both the first and second phases is estimated at $16.39 million. Completing the first phase now allows the city to complete the second phase in the next three to five years. This allows for the North and South 06-26-03-W2M to develop their initial phases. The estimated cost for the first phase is a substantial reduction from the $22 million previously estimated for a dedicated trunk main within Husky Road to the wastewater treatment plant. Engineering Services desires to tender this work later this year so that infrastructure is in place to support development of these lands in 2014," detailed the report.

The next step to be undertaken is for detailed engineering work to be done said Gord Shaw Director of Planning & Engineering with the City.

Completing the detailed engineering from the wastewater treatment plant to Darlington Street allows the municipality to determine probable cost of the trunk main from Potoski Street to Darlington, define alignment issues and propose best engineering practices when this portion is installed. Completing the conceptual work on future alignments ensures the municipality stays ahead of servicing growth in the next five to ten years in the event that development happens beyond the known limits, he explained.

The estimated cost for completing this work is identified as $673,000.00, which was unanimously approved by Council.
