Case Study #3: The Low-Flow Faucet and Smart Fixtures (Byron Highlands Townhome)

The Situation

• Two young professionals in Byron Highlands had a modern kitchen with standard faucets that delivered 2.2 gallons-per-minute (GPM) flow, leading to excessive water consumption during dishwashing and food prep.
• They wanted both style and sustainability, specifically looking to minimize water waste and introduce smart technology without overhauling the entire kitchen.
• Their quartz countertops and minimalist cabinetry needed fixtures that matched the contemporary look.

The Solution

• Replaced the existing 2.2 GPM pull-down faucet with a 1.5 GPM low-flow, stainless-steel high-arc faucet featuring a ceramic cartridge to prevent leaks. The new model includes a magnetic docking spray head for ease of use.
• Integrated a touch-activated sensor in the faucet base, enabling hands-free operation—reducing inadvertent water run time and promoting hygiene.
• Installed an under-sink recirculating hot-water system that delivers hot water at the tap within 2–3 seconds, eliminating the need to run water until it heats up.
• Added a smart leak-detection device beneath the sink. The device sends real-time alerts to a smartphone app if water is detected, preventing potential damage and waste.
• Chose matte-black fixtures to match existing hardware and accentuate the kitchen’s dark-grain, flat-panel cabinets.

The Result

• Water flow reduced from 2.2 GPM to 1.5 GPM—saving approximately 30% of water per use. Average household water savings estimated at 15,000 L per year (≈$100 CAD).
• Hands-free operation reduced unnecessary tap-on time, especially when hands were full or soiled, further cutting water waste.
• Hot-water recirculation cut wait time from over 20 seconds to under 3 seconds, saving an estimated 5 L of water per day from being run down the drain.
