Who can apply biosolids to land?

Land application may be undertaken by a water authority, a contractor engaged by a water authority, or a landowner.

Some classes or qualities of biosolids can be applied with minimal restrictions as environmental and health risks are negligible.

Lower classes or qualities of biosolids can also be applied to land, but there may be restrictions on the amount applied each year. Just like fertiliser, if applied too heavily they can have detrimental impact on the environment.
