After Care Service

We at INVAS Biosecurity regard after care as an integral part of the overall offering to our customers. On completion of an operation we will inspect the site and meet with our client to ascertain complete satisfaction with the result.

Regular monitoring of difficult sites is essential. It is a fundamental part of the INVAS Biosecurity philosophy to include the stakeholder in a close working partnership. This means maintaining regular contact and surveillance of the site.


Land Drains

Blocked land drains and culverts have been the cause of serious flooding in both rural and urban areas in recent years.

When vegetation is allowed to grow into these channels it can severely reduce the flow of water and acts as a barrier to all other debris as it is washed downriver thereby causing blockages, resulting in flooding. There is a great responsibility on Public Authorities and landowners to maintain their drains and serious consequences for those who do not.

Solutions from Invas Biosecurity

INVAS Biosecurity can work with those who are responsible for drainage or the individual drains and put in place a program that will manage and ensure that the drains are clear of debris and weeds throughout the year. We can also provide an annual treatment program to keep the channels weed-free and free flowing! This is sensitive work and the client needs to have confidence that the contractor is knowledgeable and trustworthy so that there will be no danger of risk of pollution by the use of non-registered herbicides. INVAS Biosecurity is such a company !
