Wastewater Treatment System Selection

COURSE NO: C02-009
COURSE PROVIDER: Gilbert Gedeon, P.E.
Wastewater Treatment System Selection
Course Highlights

This online engineering PDH course provides guidance on the selection process of the subsurface wastewater infiltration system. It describes various steps involved in the selection process including understanding of the prevailing design conditions, matching these conditions to system performance, establishing design boundaries and boundary loadings, evaluating the receiving environment and mapping out the site.


Selecting the appropriate system type, size, and location at the site depends on the wastewater flow and composition information, site- and landscape-level assessments, performance requirements, and the array of available technology options. Key to selecting, sizing, and siting the system are identifying the desired level of performance and ensuring that the effluent quality at the performance boundaries meets the expected performance requirements.


This 2 PDH online course is applicable to civil, and environmental engineers, as well as design and construction personnel involved with the planning, selection and design of subsurface wastewater infiltration systems.
