Environmental Assessments | Land Capability Assessment

Supplier: Porta Environmental

A Land Capability Assessment for on-site domestic waste-water management, is a comprehensive report that assesses for a particular site, the suitability and sustainability of an on-site waste water system.


The LCA should take into account a range of specific environmental features relative to the site and should give a clear indication of what the site is capable of sustaining. A detailed LCA report needs to be produced with all relevant environmental analysis contained. It should include soil typing and permeability testing and calculations for maintaining water balance with recommendations for the most appropriate type of onsite waste water treatment system.

When is a Land Capability Assessment required?
EPA Publication 746.1 states that:
"For all proposed unsewered residential developments, a comprehensive land assessment should be undertaken prior to residential development proceeding. The overall objective of the land assessment process described in this bulletin is two-fold:
To assess the capability of the site to sustainably manage wastewater within allotment boundaries; and
To identify a management program that should be put in place to minimise the health and environmental impacts of on-site wastewater management."

How will I know if a Land Capability Assessment is required?

Your Council will tell you if and when you require an LCA. In some cases if you are redeveloping a site, an LCA will be required to take into account any changes.


What are the differences between Victoria and NSW legislation?
Victoria and NSW have slightly different rules that have the same desired outcome, to protect the health of you and others and to protect the environment from onsite wastewater mismanagement. Depending on where you live and the specific details your local council requires, reports can vary slightly.

Can the Local Council deem a site to be unsuitable?
The state government legislation for Victoria and NSW is designed to protect the general health and welling being of its home/land owners, your neighbours, the general public and the environment.
Some sites are just not suitable for onsite waste water disposal. A Land Capability Assessment is designed to test the site's suitability. The more comprehensive your LCA report the better the chances of finding a suitable solution for a difficult site. The sooner the site is LCA assessed the better. Most new sub-divisions should have a LCA done. Your Council has the final say on approving all LCA applications.
