What Our Customers Say

We have since used Graham and GT Environmental Services for drainage work and septic work at our coastal property and again nothing was a problem and innovative planning to suit coastal requirements was implemented with precision.

– Elsie Lane

We contacted GT Environmental during peak season for portable toilets and at very short notice for our community event. Communication was excellent. Teresa was friendly and accommodating for our event needs. ChangeAbility and the Violence Free Network really appreciate GT Environmental Services support for our children’s event.

– Ang Turipa

There is nothing too difficult for them. These folk also have a strong civic and community focus and are very generous in their support across the region.

Graham, Teresa and their staff are people you can trust and worthy of your support.

Answers to Your Questions

How often should I clean my tank?

We recommend that you clean it every 3 – 5 years depending on the size of your tank and the number of people in your household. 

How can I look after my septic system? 

It’s good to think of your septic tank as a living thing, it’s the good bugs in here that break down waste so if you put harsh chemicals down the drain you kill the bugs. 

How long does it take? 

A simple tank clean for a normal system will take around an hour plus travel and dumping time. You can speed the process up by having the lids dug off or exposed before we get there. 

What products should I use? 

We recommend using products that are septic tank safe, you can check labels to see if they are septic or grey water safe. In our personal household we use all Eco-Store products which are readily available from most grocery stores. 

There is a smell coming from my system. 

A smell generally signifies that your system isn’t happy and this could be for a number of reasons. You may be flushing your system too frequently by putting too much water through it, or you may have killed the good bugs in your system which need to be re-kindled with a new starter like live yoghurt. It may also be a sign that it’s time to clean your tank, if it hasn’t been done in the last 3-5 years then give us a call to book the truck.
