In 2013, the Town developed the framework for a comprehensive assessment aimed at reducing inflow and infiltration which enters the waste water collection system. Since that time, the Town has been actively working with homeowners, contractors, etc. to identify, reduce and eliminate sources of inflow and infiltration from the system.
Inflow and infiltration is when clear water (groundwater or stormwater) enters the sanitary collection system requiring treatment at the wastewater treatment plant. This is important because the sanitary system is designed to be a separate system from stormwater and is not designed to handle groundwater and surface water.
Public involvement and understanding the effects inflow and infiltration has is vital to the success of the program. Since the launch of the assessment in 2013, Town staff has been working with numerous property owners whom have come forward to rectify illegal or unknown connections contributing to inflow and infiltration. Continued involvement and cooperation from property owners will be required to ensure the program's continued success.

Why are property drainage inspections needed? | ||||||
The majority of Inflow and Infiltration (I & I) takes place on private properties. I & I happen when “clean” water such as groundwater, surface water, storm water, etc. enters the wastewater collection system, requiring treatment at the Wastewater Treatment Plant. |
||||||
What problems can improper drainage connections cause? | ||||||
Sanitary sewer systems are designed to carry wastewater from toilets, washing machines, sinks or showers in homes or businesses to wastewater treatment locations. When an excess of water enters the system, such as during a major rainstorm, it can cause the system to overload and sewage backups or overflows to occur. I&I is costly because overflows can back up into basements of homes and businesses, into roads and the natural environment. I&I also puts a strain on the entire wastewater system. Treatment facilities must treat a higher volume of water flow, resulting in increased operating, maintenance and capital expenses. I&I also takes up valuable capacity at facilities –requiring costly system upgrades sooner if the problem continues. |

How do I know if I am contributing to sewer system overloads? | ||||||
Signs that your property may be contributing to sewer system overloads are:

Three (3) rebate programs are available totaling up to $3,050 per property to help property owners disconnect properly.
