What does a rainwater biofiltration system actually do?

A rainwater biofiltration system removes sediment, organic matter, odours, and roof contaminants from rainwater before it enters storage. It uses natural layers of sand, gravel, activated carbon, and biochar to improve clarity and protect irrigation equipment.

Is the system safe for garden and greenhouse irrigation?

Yes. The materials used, such as washed gravel, silica sand, activated carbon, and biochar, are safe for food-producing gardens. The system removes fine debris and helps stabilize stored water, making it ideal for drip lines and greenhouse watering.

Does the filter make rainwater drinkable?

No. A home-scale biofilter improves water quality for non-potable uses only. Treated rainwater is excellent for gardens, soil hydration, lawns, and greenhouse irrigation. Potable use would require additional treatment and certification.

How often do I need to maintain the filter?

Maintenance is simple. Monthly: rinse debris from the top layer and check flow. Seasonally: replace or recharge the activated carbon or biochar. Annually: refresh the top portion of the sand layer. This keeps flow steady and water cleaner during storage.

What size of storage tank works best with this filter?

The system pairs very well with 1000 litre IBC totes, small cisterns, or multi-tote setups. Larger greenhouses or gardens can add multiple filters or use a cascading arrangement for higher volumes.

Can this system be used year-round in Alberta?

Only if it is insulated and frost-protected. Most homeowners operate the filter during the warm season and bypass or drain it for winter. The Sustainable Life kit includes guidance for freeze-thaw conditions in Alberta.

Do I need special plumbing skills to build the filter?

No. The system is designed for everyday homeowners using common materials, basic tools, and standard fittings. The kit includes diagrams, layer depths, and step-by-step assembly and maintenance guidance.

Why does Sustainable Life recommend adding biochar?

Biochar significantly improves water quality by increasing microbial stability, reducing odour, and adsorbing organic compounds. It also supports soil health when used after filtration, which fits Sustainable Life’s circular, low-waste approach.

Cardboard to Community Gold: Building a Biological Circular Economy in Diamond Valley

Leave a Comment / Circular Economy Series, Innovation Pilots, Sustainable Living / Williams

Cardboard is everywhere in our waste stream — moving boxes, delivery packaging, food cases, and online shopping parcels. It’s light to transport but bulky to landfill, and its recycling value drops fast when it leaves town. But what if, instead of exporting cardboard, we transformed it here into products that enrich our soil, retain water, […]

Sustainability is often framed as something governments must create. In reality, the most durable sustainability already exists long before policy enters the conversation. It lives in households that repair rather than replace.In residents who conserve water because they understand its limits.In communities that value long-term thinking over short-term gain. The role of governance is not

When Sustainability Becomes Practical

Leave a Comment / Circular Economy Series, Community, Sustainability Manual, Sustainable Living / Williams

Sustainability often sounds like something distant — a future goal, a policy decision, or a technical conversation meant for experts. But in daily life, it’s far more ordinary than that. It shows up in the choices households make when something breaks, when water becomes scarce, or when monthly bills start to feel less predictable. In

From Waste to Weight-Bearing: How Glass Can Build a Local Circular Economy

Leave a Comment / Circular Economy Series, Community, Sustainable Living / Williams

In most recycling systems, glass gets a rough deal. It’s heavy, expensive to transport, and often down-cycled into low-value uses — or worse, it ends up in the landfill. But in communities like Diamond Valley, Alberta, that weight becomes an advantage when we rethink glass as a local resource, not waste. Right now, municipalities and

A Sustainability-Focused Synopsis Why Planning Matters in a Sustainability Context At the municipal level, planning is the bridge between long-term sustainability goals and day-to-day decisions. It is where climate risk, water security, housing form, infrastructure capacity, and fiscal reality are meant to converge before capital dollars are spent or land is committed. A review of
