Course Description

The quality of groundwater used cannot be compromised any longer and the servicing requirements of on-site sewerage disposal Systems cannot be ignored. With limited funds available to you the private owner or regulatory agency that have responsibility for inspection, the task of on-site sewerage treatment and disposal is becoming very difficult. With limited funds available to the owners we Believe this workshop will help you to install an effective system. You will learn numerous tips and tricks throughout the workshop to make it very practical and relevant to your applications.
