Decide which treatment system and land application system you would prefer and suits the property you wish to install it on
Consider such things as:
Arrange for a geotechnical report to be completed
If you are installing a new or upgrading an existing system, check with Council if a geotechnical report is required for your site. New subdivisions may not require geotechnical reports as information may already be on file.
A geotechnical report is not required for the installation of pump-out systems, as these systems do not dispose on-site.
The geotechnical report will detail soil characteristics and environmental constraints. The report will recommend the best type of system for the site and include calculations for the size of the disposal area. Talk to the geotechnical consultant and discuss your preferences. The most suitable system for the site may not suit you. The system you prefer may be possible but could require a specific design.
A comprehensive list of geotechnical engineers is available from the Yellow Pages.
