How One Multi-Family Property Saved Over 11,000 Gallons of Water Per Day

Commercial water efficiency expert looks for leaks. Data is fun. Here at the Portland Water Bureau we think water data is especially fun.  Even more thrilling is when water use data tells a happy story. This is one such tale.

The Water Bureau’s water efficiency team – your experts in helping save water and money – was contacted by a multi-family property owner because of unusually high water use. After our team reviewed historic water use data for the property, it was clear there was an issue – water use was six times higher than it had been the previous year!

What’s Behind the 11,000 Gallon Leak?

Water efficiency staff visited the property and found a significant number of toilets had leaky flappers. This seemly small issue was resulting in an average of over 11,000 gallons of water loss each day at the 50-unit complex.

Toilets are the number one cause of leaks in all building types, and toilets can fail before their time. It’s always a good idea to check for toilet leaks.

And here comes the happy ending.

After the leaks were identified, the property owner replaced all flappers in the building’s toilets. Today, average daily water use is back to what it was with the benefit of about $220 per day in water savings.
