Current Manure Management Practices

In American Samoa, the first step in manure management is typically to hose down the pens once or twice a day. As shown below, most pens have at least one opening along the back wall where the manure and wash-water runs out and into a concrete gutter.

After wash-down, manure is usually managed in one of three ways:


1. Use of a "cesspool" (which probably results in discharge to groundwater).

2. Direct discharge into a surface stream (in a valley or near the ocean).

3. Uncontrolled flow of manure around the perimeter of the piggery.
