Piscataway, N.J.-based American Standard says it is out to prove just how powerful around the world a toilet can be.
The company pointed to stats that show almost half the world lacks a safe way to go to the bathroom. And almost half of North Americans surveyed have no idea that lack of sanitation facilities causes 2,000 deaths per day, mainly among children. In regions of the world where water is scarce and sewer infrastructure doesn't exist, open pit latrines allow disease to spread through direct and indirect contact with human waste.
Toilet manufacturer American Standard has launched a campaign to increase awareness of this crisis and to stimulate action that protects the health of all people through well-engineered plumbing solutions
American Standard engineers have invented SaTo (pronounced SAH-toh, derived from “Safe Toilet”), a cost-effective hygienic latrine pan that uses an ingeniously simple mechanical seal and water seal to reduce disease transmission by closing off pit latrines from the open air. The company will donate hundreds of thousands of these pans to Bangladesh in 2013, one for each of its Champion brand toilets sold in North America.
SaTo was developed based on the findings from a market assessment American Standard engineers conducted last year in the Rajshahi region of Bangladesh, organized and led by International Development Enterprises (iDE). The product design team observed the widespread use of non-hygienic latrines, where users fill a pot called a “bodna” of water, and use the water to “flush” waste into the pit. The latrines, which are about 6 ft. to 8 ft. deep, are covered with a concrete slab in which a plastic toilet pan is encased. The pans have a large opening that allows waste to freely fall into the pit, but no seal to prevent transmission of pathogens back out of the pit via flying insects.
The team also visited manufacturing facilities to understand existing capabilities and cost structures in order to develop a solution that could be economically mass-produced in Southeast Asia.
After eight months of development at the American Standard New Product Design center at the company headquarters in Piscataway, N.J., successful field testing on SaTo was completed in Bangladesh this past January and February. Users especially appreciated how the small amount of water retained after each use created an airtight seal that reduced odors.
“The SaTo retail price is well within the price range that triggered purchase intent from field trial participants,” said Jim McHale, American Standard VP product development, who led the field studies, as well as the latrine design team. “The price point allows for profit-taking at every step of the supply chain, yielding not just safer sanitation, but also a sustainable business model to drive widespread adoption and help reduce poverty.”
