Webinar: Water Efficiency in Ontario: Best Practices to Lower Your Operational and Capital Costs

Posted March 1, 2021

On February 25, PPG hosted Indra Maharjan (Director of Innovation, Technology and Alternate Delivery at Ontario Clean Water Agency) and Chris Le Conte (President of SMART Watering Systems Inc. CIC, CLIA, WSIP) for Water Efficiency in Ontario: Best Practices to Lower Your Operational and Capital Costs. The webinar explored municipal water efficiency programs that help Ontario businesses lower their capital and operational costs.

During the Q&A portion of the webinar, we received many questions from the audience for both Chris and Indra. Below, you will find their responses to some of the questions we were not able to address during the session.

Water Management and the Blue Economy Water and Energy Efficiency in Ontario


Q&A with Chris Le Conte and Indra Maharjan

Q&A with Chris Le Conte, President of SMART Watering Systems Inc. CIC, CLIA, WSIP

Q: Is there an “average” ROI for water efficiency projects?
Typically for indoor it is less than 1 year (for the tenant that detects a leak early). The building owner (who typically does not pay the water bill) looks like a good landlord/manager by providing technology or a service that ultimately provides value to the tenant. 

Q: Are there any ground sensors to communicate with controllers in irrigation systems so when there is enough water, the irrigation system will not be triggered?
Yes, however these are more suited to residential application. They are not widely used due to varying soil types and microclimates on commercial properties. 

Q: What are the acceptable systems to collect rainwater and reuse it in irrigation or cleaning purposes?
Concrete tanks, polyethylene tanks, modular systems etc. 

Q: Have you looked at financial viability of 100% irrigation efficiency (e.g. not irrigating)?
Yes, we have clients that have done this with select properties. There are mixed results. Landscapers will not guarantee new plantings if water not supplied. After 7-10 days of hot dry weather we typically get called in to turn the systems on. 

Q: What service providers can advise property owners on baseline usage or leak detection?  
This is one of our business areas. Please reach out and I can steer you in the right direction based on your needs and locations.  

Q: Do residential toilets regularly leak? If so, how can one determine if that is occurring?  
You can hear them, use dye tabs or install technology on your meter. 

Q: Can wastewater be used for irrigation after treatment in various pockets/municipalities?   
You can hear them, use dye tabs or install technology on your meter. 

Q: What measurement devices offer the best combination of value/cost/ease of installation/accuracy?    
I have had a lot of success with the Alert Labs Flowie product but there are many products locally available. A good place to start would be researching “water leak detection”. 

Q: How many landscaping / irrigation companies in the GTA have the WSIP?   
Approximately 80 companies. 150 individuals. Of those 80 approximately 10 perform assessments on a regular basis. 

Q: What technology is used for monitoring indoor water management? 
There are many technologies available.A good place to start would be researching “indoor water management leak detection flood detection”

Q: How should a property owner get started if interested in sprinkler system efficiency? 
Contact Landscape Ontario or their irrigation/landscape contractor.

Q&A with Indra Maharjan, Director of Innovation, Technology and Alternate Delivery at Ontario Clean Water Agency

Q: Can wastewater be used for irrigation after treatment in various pockets/municipalities?  
Treated WW is discharged into water bodies so technically it is already used for various purposed downstream. 

Q: Please elaborate on the U.S. EPA eTWh metric and how it can be used in municipal water conservation programs? 
The established energy and carbon intensity by US EPA or AWWA and other organization can be used as rule of thumb to be attached to water conservation KPIs. 

Q: Why is it important to showcase implementation case studies? 
Highlighting project is especially important as it motivates the project team, helps share the outcome of projects to broader community and increase knowledge and awareness among public the excellent work utilities and municipalities are doing.   

Q: How can we influence more municipalities in Ontario to consider adoption of water conservation measures for businesses?
Adding co-benefits of water savings in preparation of business case and effective communication on outcome of these programs is key to more adoption of these programs.  

Q: How difficult is it to translate the conservation of water to greenhouse gas / carbon footprint reductions? What are some of the areas to overcome this?
Industry derived conversion factors can be used with some verification on local level.
