Multi-Level Water Detector
CWSF · 2026 Digital Technology
Overview
This project touches on how we use a Multi-Level Water Detector to prevent wastage of water due to negligence and not being able to see of know when the overflow does happen. With the device we use a breadboard, LED light, 2 wires, , 330 ohms resistor, tank model, buzzer, and an off and on switch that is all powered by a 9 volt battery. It’s also important that homes have this device in their tanks, especially sewage tanks — as it tends to overflow the most. Also being a great addition to places near the ocean to detect when the water reaches near ground level due to coastal flooding. Imposing danger to infrastructure, tourists, and residents.

Hello, my name is Kaiden and my partner is Keayeanna. We are students from Poplar River First Nation. Today, we are presenting our project called the Multi Water Level Detection System. This project was created to address real challenges in our community related to water management. We often experience issues such as water tanks overflowing, pumps getting damaged when the water is low, these problems can lead to water waste, and equipment damage. Our solution is a system that can automatically monitor water levels in a tank. We used sensors placed at different levels—low to high—to detect how much water is in the tank at any time. It’s important because it reduces water waste, saves energy, and makes the system more efficient. So thank you for listening. Merci. Miigwech.
Why?
Why?
Reliable access to water is a daily priority in Poplar River First Nation. The community continues to face persistent water-related challenges, including:
Inconsistent water supply levels in storage tanks, especially during high usage periods
Overflow or wastage when tanks are overfilled due to lack of monitoring
Pump inefficiency or damage when water levels are too low (dry running)
Limited real-time information about tank levels, requiring manual checking
Broader concerns about water management, including seasonal flooding and changing water conditions in surrounding rivers and lakes
These issues affect:
Daily water availability
Infrastructure reliability
Energy use and costs
Community health and safety
The project was created to provide a simple, reliable, and locally manageable solution to monitor water levels and improve water system efficiency.
How?
How
The Multi Water Level Detection System uses sensors and simple electronics to monitor water levels in tanks while water is being pumped.
Core Functionality:
Water level sensors are placed at different heights inside the tank (low, medium, high levels)
These sensors detect the presence of water at each level
A control system (microcontroller or circuit) processes the signals
The system can:
Indicate current water level (e.g., LEDs/display)
Trigger alerts when water is too low or too high
Automatically turn the pump ON/OFF based on water levels
Multi-Level Detection:
Low Level: Indicates tank is nearly empty → pump turns ON
Mid Level: Normal operating range
High Level: Tank is full → pump turns OFF
Adaptability:
The same system design can be extended to:
Water reservoirs
Community water storage systems
Rivers and lakes (for monitoring rising or falling levels)
What?
What
The project is a smart water monitoring and control system that:
Tracks water levels in real time
Prevents overflow and water waste
Protects pumps from running dry
Automates part of the water management process
Provides visual or alert-based feedback
It combines:
Basic electronics (sensors, circuits)
Practical engineering design
Real-world application relevant to the community
So What?
So What?
This project has direct and meaningful benefits:
Improved Water Management
Reduces water waste from overflow
Ensures tanks are filled efficiently
Protection of Equipment
