Did You Know?

You produce approximately 66 lbs. of biosolids each year!


You’re saving soil with each flush – you are a valuable part of the production line that starts when you flush, creates biosolids, and ends by saving soils.

Biosolids are what you eat

Biosolids contain what you flush down the drain: water, plant and animal matter, sand, nutrients, microbes (the good kind!),  and small amounts of metals (many of which are plant essential nutrients).

Producer responsibility

Every year, an additional 2,000 chemicals are introduced to the market, many of which are found in personal care products we put on or in our bodies.

Next time you purchase a product, pay attention to what’s in it. By avoiding products containing damaging chemicals (e.g. triclosan), you are ensuring a higher quality of biosolid products.

Quality is #1 for #2

Biosolids are science-based, rigorously tested, and regulated by federal and state environmental agencies, biosolids quality is a guarantee you can bet on.

Get involved

You’re part of the supply chain

Biosolids are something that we all contribute to.  It’s a product that we can actually have some influence over it’s quality, use and future.  Next time you’re looking for a locally made product for your garden or landscape project, look no further than your very own biosolids product.

Making microbes happy

University of Arizona studied the long-term sustainability of using biosolids as a fertilizer and soil conditioner and found that biosolids positively affect soil microbes, enhanced the soil with organic matter and nutrients, and risks from biosolids to human health were low.

How you can resource responsibly at home

The next time you purchase toothpaste or cleanser, read the label.  If triclosan or plastic microbeads are ingredients, find an eco-friendly alternative and let your retailer know how these impact the Puget Sound (or our local waterways). Research has shown that both ingredients do not break down in our environment and directly impact the health of aquatic species.
