| Short Description |
In principle, the land application of wastewater uses the physical, chemical and microbial properties of the soil and vegetation to remove contaminants from the applied wastewater. The upper soil-plant zone is used to stabilize, transform, or immobilize wastewater constituents and support crop growth, leading to an environmentally acceptable assimilation of the waste. When proper design principles are used, land application is a desirable method of wastewater treatment. (Also see abstract below) | |

| Abstract | Long Description |
In principle, the land application of wastewater uses the physical, chemical and microbial properties of the soil and vegetation to remove contaminants from the applied wastewater. The upper soil-plant zone is used to stabilize, transform, or immobilize wastewater constituents and support crop growth, leading to an environmentally acceptable assimilation of the waste. When proper design principles are used, land application is a desirable method of wastewater treatment. This document defines the minimum content and considerations required for the preparation of an engineering report for land application of industrial wastewater as provided in WAC 173-240-130(2) and as defined in WAC 173-216-030(7). An engineering report is required prior to construction of new facilities, facilities modifications, or in response to permit conditions or administrative orders. A properly designed and operated land application system should: Deviations from these guidelines may be accepted when there is appropriate technical and engineering justification. |
