Water and wastewater infrastructure is often located in or adjacent to natural areas where the natural slopes of stream valleys provide gravity flows for water supply distribution and conveyance of sewage effluent. This makes natural resource assessments and permitting, and environmental construction inspection common and critical elements in water and sewer improvement projects.
