Once the material has been taken to a Surface Disposal site, it is not used later. This technology is primarily used for biosolids, although it is applicable for any type of dry, unusable material.'''
One application of '''Surface Disposal that is shown on the System Templates is disposal refers to the disposal stockpiling of dry cleansing materialssludge, such as toilet paper, corn cobs, stones, newspaper and/faeces or leaves. These other materials can not always that cannot be included along with other water-based products in some technologies and must be separatedused elsewhere. A rubbish bin should be provided beside Once the User Interface material has been taken to collect the cleansing materialsa surface disposal site, it is not used later. Storage refers to temporary stockpiling. Dry materials It can be burned (e.g. corn cobs) or disposed of along with done when there is no immediate need for the household waste.

The main difference between Surface Disposal and Land Application is the One application rate.

When there is no demand for or acceptance of the beneficial use of sludge, it can be placed in monofills (sludge-only landfills) or heaped into permanent piles. Temporary storage contributes to further dehydration of the product and the die-off of pathogens before it is used.
===Design Considerations===
Landfilling sludge along with municipal solid waste (MSW) is not advisable since it reduces the life of a landfill, which has been specifically designed for the containment of more noxious materials. As opposed to more centralized MSW landfills, surface disposal sites can be situated close to where the sludge is treated, limiting the need for long transport distances.
The main difference between surface disposal and land application is the application rate. There is no limit to the quantity of sludge that can be applied to the surface since nutrient loads or agronomic rates are not a concern. Attention must be paid, however, to groundwater contamination and leaching. More advanced surface disposal systems may incorporate a liner and leachate collection system in order to prevent nutrients and contaminants from infiltrating the groundwater. Sites for the temporary storage of a product should be covered to avoid rewetting by rainwater and the generation of leachate.

==Adequacy=Appropriateness=== Since there are no benefits gained from surface disposal, it should not be considered as a primary option. However, where sludge use is not easily accepted, the contained and controlled stockpiling of solids is far preferable to uncontrolled dumping. Storage may, in some cases, be a good option to further dry and sanitize a material and to generate a safe, acceptable product. Storage may also be required to bridge the gap between supply and demand. Surface disposal and storage can be practiced in almost every climate and environment, although they may not be feasible where there is frequent flooding or where the groundwater table is high.
Since there are no benefits gained ===Health Aspects/Acceptance=== If a surface disposal and storage site is protected (e.g., by a fence) and located far from this type of disposal technologythe public, it there should not be considered as a primary optionno risk of contact or nuisance. However, where acceptance towards biosolid use does not exist, the contained and controlled stockpiling The contamination of biosolids is far preferable to uncontrolled dumping. Biosolids can groundwater resources by leachate should be applied in almost every climate prevented by adequate siting and environment, although they design. Care should not be stored where there is frequent flooding taken to protect the disposal or where the groundwater table is highstorage site from vermin and pooling water, both of which could exacerbate smell and vector problems.
==Health Aspects/Acceptance=Operation & Maintenance=== Staff should ensure that only appropriate materials are disposed of at the site and must maintain control over the traffic andhours of operation. Workers should wear appropriate protective clothing.
