Ogogrow Production

Biosolids used in the creation of Ogogrow are derived from the wastewater treatment process. The name “biosolids” is given to the solid waste remaining once the wastewater treatment process has been completed; biosolids contain macronutrients and organic matter needed to replenish soil and retain moisture.

Each day two to three truckloads of dewatered biosolids arrive at the Ogogrow Production Facility in Winfield from the City’s Wastewater Treatment Facility on Raymer Avenue. The biosolids are then mixed with enough wood waste (wood chips or hog fuel) to create an environment where aerobic bacteria can flourish.

The resulting mix is piled into numbered windrows where perforated pipes attached to blowers distribute air to promote effective decomposition. As aerobic bacteria move and multiply, the piles heat up often exceeding 60 degrees Celsius. The heat kills pathogens making the material safe to handle after three days.

Rapid decomposition continues for 21 days at which time the compost is then repiled and allowed to continue composting for another 30 days. As the compost matures it gets darker and takes on an earthy smell.

The compost is then screened to remove excess wood waste which in turn is used again in the initial mixing process. Testing is conducted for pathogens, nutrient value, moisture, PH and metals content. Test results are submitted to the provincial Environment Ministry for approval.

Ogogrow is distributed in bulk to retail outlets, landscapers, orchardists and nurseries. The City sold 14,430 cubic yards of Ogogrow in 2004 for $123,520 as well as 2,425 cubic yards of Glenmore Grow for $58,320. Total compost sales generated $181,840.
