The Competition

Everything You Need To Know

Our fall 2022 competition is being hosted in partnership with the City of London

Competition Overview

The Problem

Stormwater, its impacts, mechanisms, and mitigation strategies are poorly understood by the public. This results in challenges for civil services to justify large capital investments into infrastructure, or programs and policies to protect public property and environmental health. In addition, the public is often ill-equipped to understand the impacts of their own actions on aging infrastructure, are not informed of practices that can protect themselves, and may contribute to the problem through their own actions. Standard public information sessions, pamphlets, online information, and newsletters have not been effective in enlightening the public. This knowledge-gap is seen in all age groups and backgrounds.


The Challenge

From recent trials with elementary school students, hands on experiences were found to be much better at engaging and instilling understanding than traditional outreach methodologies. The challenge then is to create professional, safe, cost-effective, and easily deployable “experiences” that can educate the public on various stormwater topics.

What You Need To Do

Competing teams will design and create “experiential” kits (similar to those by KiwiCo) that can be manufactured by the City of London and made available for a target audience.


Ideally, the kits should be suitable for a large range of age groups; however, it would be acceptable if it only targets grades 3 to 8. The kits may be deployed by City staff at information workshops for large infrastructure projects to assist with understanding the value of stormwater projects, sent to schools for use in the classroom, or made available for loan in the library for the public.


Simple and safe materials, reusability, and intuitive design are paramount. The City of London intends to create working prototypes and short runs using CNC machines, 3D printers, and laser cutters.

Suggested Lesson Topics

  • How drainage works on different surface types
  • How homes are designed for drainage
  • How soil type impacts drainage
  • How engineered river infrastructure (such as those in the Thames River) work (Dikes, Dams)
  • Stormwater pond design features
  • A stormwater pond’s purpose (sediment and erosion control, nutrient removal)
  • The concept of a “subwatershed”
  • How City infrastructure reduces flooding
  • Low impact development measures
  • Climate change considerations

In addition to the resources provided by the City of London and Rain It In, student teams are allowed and encouraged to do their own research and make their own connections with industry professionals as needed.

Additional Resources

Flood Control Structures in London

Fanshawe Dam & Reservoir – Upper Thames River Conservation Authority

Recreational Dams – Upper Thames River Conservation Authority

Flooding – City of London

The City of London Dyke System – Upper Thames River Conservation Authority

The original West London Dyke (WLD) was constructed in the 1880’s along the Thames River.  After extreme floods in 1937 and 1947 left thousands of homes underwater, sections of the dyke were raised in order to increase protection.    To further protect the homes within the floodplain, the new dyke was designed to protect against the 1:250 year flood event.  To date, over 1.4km of the WLD spanning from the Forks of the Thames to north of Oxford Street has been upgraded to this higher level of protection.  The remaining west leg spanning from the Forks to Cavendish Park is now being worked on for completion.


Here are some of the organizations our mentors have been from:

If you are interested in participating as a mentor, please apply here.

Project Deliverables

  • Short description from creators introducing submission and outlining: Name, Lesson/Message, Inspiration, Suitable Age Groups, What they Feel Makes the Experience Unique and Engaging
  • A 5-minute demonstration video using prototype of kit (for demonstration only, physical asset is property of creators)
  • List/inventory of reusable components and consumable components
  • List/inventory of costs for all components (including vendors)
  • Digital files of documentation (manuals, guides)
  • Digital files of STL/Model/gcode of component parts
  • Digital files of graphics used


For the purpose of the competition, teams do not need to concern themselves with external packaging (e.g. what box everything will come in). If they do design packaging, it will be excluded from overall cost metrics for comparison purposes.


All project deliverables should be submitted to the Google Drive for evaluation by November 6th, 2022 at 11:59 PM EST. A unique link will be provided to each student team after registration closes to use for their submission.


The competition will be hosted virtually and registration is open to students studying at a Canadian college or university.


Teams should consist of three to six members.


As climate change is a multi-sectoral problem, we recommend that participants build diversified teams across various programs to gain different perspectives and skills useful for developing a successful innovation. Students do not need to be attending the same educational institution to be on the same team.


We also strongly encourage student teams to work with mentors from their institution’s internal incubator or accelerator programs.


The deadline to register your team is October 9th at 11:59PM EST.

Judging and Evaluation

The judging panels will be comprised of individuals from a variety of backgrounds which could include municipal, academic, engineering, regulatory, conservation, communications, public education, and outreach. The number of judges and their affiliations will be shared throughout the competition.


There are two different judging panels who will evaluate the project submissions during the competition:


  • The first panel of judges will evaluate all project submissions due on November 6th, 2022 at 11:59 PM EST to identify the top five teams
  • The second panel of judges will evaluate the live demonstrations presented by the top five teams on November 30th, 2022 from 1:00 PM – 3:00 PM EST.


The teams who will be invited to pitch live on November 30th, 2022 will be notified by email by November 20th, 2022. Teams who did not make it to the top five are allowed and encouraged to attend the live demonstration event.


The scoring sheet has been designed for the judges to use to evaluate the project submissions. The same evaluation criteria will be used by both panels of judges as the basis for judging all submissions.


Rain It In will reimburse up to $100.00 per eligible team for costs associated with the creation of a prototype.

About the Project Host: The City of London

The City of London is the municipal government for London (Canada), located in southwestern Ontario with a population of approximately 422,000. London is the 11th largest metropolitan area in Canada and is among the fastest growing cities in the country. Situated along the Thames River and within the Upper Thames River Conservation Authority (UTRCA) area, London experiences flooding during severe weather events. In response, the City is working to improve its aging infrastructure.


London was one of the first cities in Ontario to create a stormwater charge to support the implementation of stormwater infrastructure that protects the City, residents, and the environment. Today, the City continues to make rapid improvements to mitigate the impacts of climate change and the increasing frequency of severe storms.
