Septic Upgrade

Septic Tank Removal/Upgrade

Your septic system might need replacement due to age, damage, failure, regular overloading and most importantly, if it’s contaminating your water supply or the environment.

Septic tanks typically have a lifespan of 20-40 years depending on usage and maintenance.

Major indicators that your septic tank is failing include:

Bad odours around the septic tank or surrounding yard.
Constant wet or spongy patches around the septic tank or the drainage area.
Gurgling or strange noises in the plumbing system.
Unexplained slow drainage from toilets, showers, baths etc.
Bright green, spongy lush grass over the septic tank or drainfield, even in dry weather.

See below for a step by step guide to replacing your septic system with a Wastewater Treatment System.

Unsure if your septic system is operating effectively? Contact EnviroTas and we can arrange an inspection by one of our highly experienced Wastewater Specialists.

STEPS FOR REPLACING YOUR SEPTIC TANK SYSTEM:

STEP 1

Design

1a: Wastewater Assessment & Design Report

You will need to have a site wastewater assessment & design report completed before you can proceed with any Wastewater Treatment System replacements or upgrades.

This will need to be completed by a wastewater engineer and will cost circa $2000.00. It is a comprehensive document that includes a soil report and will detail items such as your site soil profile, wastewater classification, and property wastewater loadings. This report will ultimately establish the type of wastewater treatment system, and the size and type of wastewater disposal method required for your property.

1b: Preferred Location

If you have a preferred location for your system it is best to discuss this with your Wastewater Engineer and EnviroTas now. This will ensure that the design is specified around your requirements.

(Please note that there are legal requirements around the positioning of Wastewater Treatment Systems in relation to dwellings, boundaries etc. The wastewater engineer can provide more detail on this).

How do I contact a wastewater engineer?

There are a number of wastewater engineers that service the Tasmanian market, please find contact details below. EnviroTas has worked with all these companies in some capacity, however please note the names are not shown in any particular order or preference.

STEP 2

Pre-Installation

2a: Property Assessment

Once you have received your assessment and design report, please forward this to sales@envirotas.com.au. If this report specifies installation of an Advanced Secondary Treatment System, such as an EnviroTas-AS, we will then organize a date/time to visit your property. This is to confirm we can complete the installation of your new wastewater system as per the approved design.

If another type of wastewater treatment system has been specified, EnviroTas can assist you with finding a contractor to complete these works.

2b: Quote Provision

Once we have assessed your site, we can then provide you with an accurate quotation to complete the works. Once the quote has been provided, we will call you to go through everything in detail and answer any questions you may have.

2c: Application for Plumbing Permit

Once you have approved our quotation, we need to apply for a plumbing permit. This application can be handled by you or can be done by EnviroTas or your plumber on your behalf. There is a cost associated with this, and this cost differs with each local council. Once you have received your plumbing permit, please forward this to EnviroTas, as all works are required to be completed under this permit.

Please don't hesitate to to contact us to discuss any aspect of the quote, we understand this is a significant project for a homeowner.

STEP 3

Site Works

3a: Removal of your Septic System

Your old septic tank and drainage field will need to be decommissioned and removed. Council will specify the method; however these are usually pumped out and crushed/buried, or dug out and removed. In some cases, the septic tank may be retained in place to provide a further layer of primary treatment

3b: Installation of your new system

EnviroTas will complete the installation of your new wastewater treatment system and treated wastewater disposal area in accordance with our quotation for works.

3c: Documentation

Once site works are complete, EnviroTas will complete and lodge the required documentation with local council.

3d: Commissioning

Once your new system is connected electrically, an EnviroTas technician will attend site and commission the system for operation. A commissioning certificate will be provided.

STEP 4

Servicing and Maintenance

EnviroTas will take care of things from here!

It is a condition of your plumbing permit and system accreditation that your system is serviced on an ongoing basis by a licensed Wastewater Service Technician. Our team of service technicians at EnviroTas have many years of experience and will ensure that your system is kept working effectively and efficiently.

The EnviroTas-AS is accredited for 6-monthly servicing. (Where the irrigation disposal is below ground) This means that ongoing service costs are some of the lowest on the market, most other systems available require quarterly servicing.

The first service will take place at time of Commissioning (installation day)

You will receive a User Manual Pack from EnviroTas which includes a Service Agreement Contract. Please complete the form and return to EnviroTas sales@envirotas.com.au so we can continue to service your system.
