Is this assessment for me?
Start with a free visit if any of these sound familiar.
You do not need to know what equipment is installed before requesting an assessment. “Not sure” is a useful place to start.

It is finished, used for storage or contains equipment and belongings you want to protect.
You want earlier warning.
You want useful information before a hidden sewer-backup issue becomes visible damage.
You own or manage property.
Homeowners, landlords and property managers can request a clearer flood-protection plan.
Know what is protecting your home
Flood protection should never be a guess.
A sewer backup can develop below floor level and out of sight. HARB helps you understand the layers protecting your basement before there is a problem.

Your free assessment
Leave the visit knowing what deserves attention.
HARB reviews what is visible and accessible, explains how the current setup works and identifies practical next steps in order of priority.
- Exterior grading, downspouts and visible drainage concerns
- Visible foundation entry points and basement moisture
- Sump-pump arrangement and backup-power gaps
- Backwater-valve presence, access and maintenance considerations
- Where Qixli monitoring may add an early-warning layer
- A written priority list for immediate, recommended and optional work
A layered flood-protection plan
Add earlier warning to the physical protection your home needs.
Qixli is one early-warning layer within a broader plan. HARB can also assess backwater valves, sump systems, backup power, waterproofing and drainage needs, then recommend what should come first.

Questions before the visit
Flood-protection answers, without the guesswork.
Start with what you know. “Not sure” is a perfectly useful answer during the first conversation.
Book a Free Flood Risk AssessmentIs the Flood Risk Assessment really free?
Yes. The initial visual, non-invasive assessment is free and there is no obligation to proceed with installation or other work.
What if I do not know whether I have a backwater valve?
That is completely fine. Confirming what is currently installed is one of the purposes of the assessment.
What does HARB review during the assessment?
HARB reviews readily visible drainage, grading, foundation, basement-moisture, sump, backup-power, backwater-valve and plumbing conditions, discusses the home’s flood history and provides a written priority list.
What does Qixli do?
Qixli monitors conditions at the sewer connection and uses cellular communication to send a signal through the provider-managed monitoring service when sewer-backup risk is detected.
Does Qixli prevent every flood?
No flood-protection system can guarantee that flooding will never happen. Qixli is designed to provide earlier warning so you can respond sooner.
Does HARB install backwater valves?
Yes. If the assessment finds that your home does not have a backwater valve, HARB can assess the site and provide a separate installation quote.
Who can request an assessment?
Homeowners, landlords and property managers within HARB’s Niagara and Golden Horseshoe service area can request an assessment.
Do I still need protection if I have a backwater valve?
Possibly. A backwater valve addresses a specific sewer-backup risk but does not address sump failure, groundwater, foundation intrusion, exterior drainage or every other source of water.
What if I already have a sump pump?
HARB can review its apparent condition, arrangement, discharge route and whether a backup layer is present. Having a pump does not mean every related risk has been addressed.
Can a home with a separate sewer system still have flood risk?
Yes. Property conditions and sources of water vary. A visual assessment helps identify which visible risks may be relevant to the specific home.
Who manages Qixli monitoring?
The monitoring provider manages the $19.99 + HST monthly subscription and ongoing monitoring service. HARB performs the professional installation and annual on-site service.
