Biosolids are the treated organic solids from wastewater treatment plants. They are rich in nutrients and organic matter which help to create healthy, high quality soil necessary for the growth of vegetation. Using Greater Vancouver Regional District biosolids in the project demonstrates a more sustainable, closed system of nutrient cycling. Instead of disposing of biosolids or hauling biosolids to sites further afield, the nutrients and organic matter are returned to nearby land, which can then avoid the use of chemical fertilizers. This saves money and reduces impacts on the environment as less transportation means lower fuel consumption and lower greenhouse gas emissions. In September 1999 and September 2000, 352 dry tonnes (1,366 bulk tonnes) of biosolids and 1,999 dry tonnes of biosolids compost (4,124 bulk tonnes) was used on the 13.6 ha site.
With the first phase of the project complete, Aldergrove Bowl has already become a popular recreation site for walkers, runners, cyclists, and equestrians. More than 10,000 native saplings and shrubs, such as hazelnut, western hemlock, and red flowering currant have been planted at this
restored site.
