Great news!

Craft3 has received $20 million from the Washington State Department of Ecology to continue providing affordable Clean Water Loans to homeowners across Washington.

When a septic system fails, families don't have the luxury of waiting. Repairs can cost $20,000–$45,000 or more, creating an unexpected financial crisis that threatens homes, public health, and clean water. This investment ensures that homeowners — especially those in rural and underserved communities — can continue accessing the financing they need when they need it most.

Since 2016, this partnership has:
💧 Helped more than 2,500 households repair or replace failing septic systems
💧 Deployed more than $70 million in affordable financing
💧 Protected families, drinking water, and the health of communities across the state

Heather Watts, OSS Program Supervisor at the Department of Health, reflects: "This essential program helps communities protect public health and improve the quality of water resources by helping homeowners access the funding needed to address failing septic systems before there is a greater financial and environmental impact."

Read the full announcement to learn how this long-standing partnership is protecting Washington's people and waterways for years to come.

(Ready for Fall 🍁💦)

Before 1775, many cities were filled with an awful stench, and foul air was a constant threat to homes.

Then a Scottish watchmaker and inventor named Alexander Cu***ng patented a device that would eventually change the world.

In 1775, Cu***ng created the first flushing toilet with an S-trap. This was a simple but brilliant design with a bend in the pipe that held a plug of water after each flush. 🚽

This small amount of water created a seal, blocking dangerous and foul-smelling sewer gases from seeping back into the house.

Now, a flushing commode had actually been invented much earlier. Sir John Harington designed one for Queen Elizabeth I all the way back in 1596.

But Harington's version lacked a trap, so the problem of sewer gas remained. Cu***ng's innovation was the piece that truly made indoor toilets safe and practical.

This invention didn't change things overnight, as it took a long time for cities to build the needed plumbing infrastructure. Still, Cu***ng’s design was the foundation for the modern sanitation that we rely on today. 💡

His simple, life-saving S-trap principle is still used in toilets all over the world.
