Description:
The results of two studies are reported: (1) the effects of construction practices upon soil hydraulic properties; and (2) field examination of the effects of operational strategies upon soil infiltration properties. The investigation of construction practices showed that heavy machinery traffic significantly reduces the porosity and infiltration rate of the bed. The degree of damage varies with soil texture, structure, and moisture content. Field trials demonstrated that a damaged absorption bed can be restored by removal of the compacted and sheared layers. The investigation of operational strategies consisted of three application methods, each employing three loading rates. Soils with similar hydraulic properties and segregated and combined wastewaters from typical rural single-family homes were used.
