Rakesh Sharma, P. Eng. with GSS Engineering Consultants provided a presentation to illustrate an assessment study that was completed to determine the impact of the following known items on the rated water and waste water capacity in Durham:
- Sunvale subdivison
- Broos subdivision
- Redevelopment of Rockwood Terrace
- Un-named subdivision 1
- Un-named subdivision 2
- Infilling/redevelopment
- Provincial policy impact
Mr. Sharma noted that there is a shortfall in capacity when factoring all known items. He also noted that the recent water audit indicates water loss based on the variations in daily numbers.
Mr. Sharma recommended next steps to assist with the water and wastewater capacity concerns.
The following next steps are for water capacity concerns:
- leak detection survey (completed)
- investigate new source of water supply
- implement watermain replacement program based on age, material and water breaks history
- stop water wastage from the 15 houses that leave taps running during the winter months
- monitor water records every 2 years (to determine impact of Sunvale and Broos subdivisions)
- water distribution modelling
The following next steps are for wastewater capacity concerns:
- undertake smoke testing of entire collection system
- CCTV inspection of select sanitary sewers
- implement manhole inspection program
- sanitary sewers upgrading program (replacement or CIPP lining)
- monitor sewage flow records every 2 years
- collection system modelling
- investigation to enhance WWTP and SPS capacity
Mayor Robinson thanked Mr. Sharma for his presentation.
