If you have any used concrete to dispose of, consider recycling it before taking it to cleanfill/landfill.  Concrete can be crushed and used as recycled aggregate.  Atlas Concrete in Silverdale may be able to recycle your concrete. 

Cleanfills

Materials such as uncontaminated soil, bricks and concrete (that will have no adverse effect on people or the environment when buried) can be taken to a clean-fill.  All clean-fills in the district are privately owned.
