About OTG TEC

Engineering a more
sustainable future.

Custom-built energy and water solutions for business, industrial, residential and community applications.

Who we are

Practical thinking. Sustainable solutions. Built around your needs.

At OTG TEC (Off The Grid Technologies), we develop custom-built energy and water solutions designed around the unique needs of each client, site and operation.

Our products are carefully designed by our team with a focus on quality, self-reliance and peace of mind. From solar power systems to water treatment and wastewater recovery, we bring together tried-and-tested technologies and automated systems to help essential services work reliably in the background.

We believe clients should be able to turn on the lights, open a tap or flush a toilet without having to worry about the complex systems that make those everyday services possible.

OTG TEC water treatment infrastructure
What we do

Three connected capabilities. One considered approach.

Energy, water and wastewater are often interconnected needs. OTG TEC considers how these systems can work together to support the way a property, business or facility operates.

Solar panels for off-grid energy

Solar and off-grid energy

Solar power systems can support greater energy independence and can be integrated with water treatment systems to enable partial or complete off-grid operation, depending on the site's requirements.

Water treatment equipment

Water treatment

Small-scale water treatment systems, with capacities from approximately 1,000 to 50,000 litres per day, are designed to produce high-quality drinking water from different source-water types.

Wastewater treatment facility

Wastewater recovery

SaniStation systems use Sequencing Batch Reactor technology to treat domestic or industrial wastewater for suitable reuse or discharge.

Water treatment expertise

Turning different water sources into a dependable supply.

OTG TEC water systems are designed to treat groundwater, surface water, wastewater and seawater to produce high-quality drinking water.

Because every water source and site is different, the treatment solution needs to respond to the characteristics of the incoming water and the intended use. OTG TEC's small-scale systems range from approximately 1,000 to 50,000 litres per day.

Where appropriate, these systems can be coupled with OTG TEC solar power solutions to support partial or complete off-grid operation. This integrated approach can be relevant to properties, facilities and operations where reliable access to utilities is an important consideration.

SaniStation technology

Wastewater treatment designed with recovery in mind.

OTG TEC's SaniStations use Sequencing Batch Reactor (SBR) technology to treat domestic and industrial wastewater.

The treated water may be suitable for applications such as irrigation and toilet flushing, or for discharge, subject to the relevant quality requirements, standards and site conditions.

The technology is designed to manage the activated sludge generated during the treatment process. This is an important part of operating a wastewater treatment system effectively and responsibly.

Our approach is to consider the full treatment process, from the incoming wastewater through to the intended reuse or discharge outcome.

Automation, monitoring and support

Intelligent systems. Greater operational visibility.

The systems OTG TEC designs and produces are automated and can be controlled and monitored remotely by the client or by OTG TEC, where required.

01

Automated operation

Systems are designed to operate through automated processes, reducing the need for constant manual intervention.

02

Remote access

Remote control and monitoring can be made available to clients or OTG TEC, depending on the operating arrangement.

03

Daily monitoring

Plants in OTG TEC's care are monitored daily to keep track of operational performance.

04

Reports and diagnostics

Clients receive monthly and exception reports. Plant diagnostics can alert OTG TEC engineers to faults so that action can be taken.

Who we work with

Solutions for businesses, property owners and communities.

Our work is relevant to both organisations with complex operational requirements and individuals looking for dependable energy or water solutions. We start by understanding the application, scale and practical needs of each client.

B2B

Business and industrial clients

For commercial properties, industrial operations, agricultural businesses, hospitality facilities and other organisations, utility interruptions and resource constraints can affect daily operations.

OTG TEC can explore integrated energy, water treatment and wastewater solutions shaped around site demand, operating conditions and ongoing monitoring requirements.

B2C

Residential and individual clients

For homeowners, property owners and individuals, reliable electricity and access to quality water are essential to comfort and peace of mind.

OTG TEC can discuss solar and off-grid energy options, water treatment needs and suitable solutions for properties where greater self-reliance is a priority.

Our philosophy

Technology that works quietly in the background.

Our goal is to provide utility services that work so reliably that clients can focus on what matters to them.

When someone turns on a light, opens a tap or flushes a toilet, they should not need to think about the engineering, treatment processes or automation behind that service. OTG TEC aims to design and support systems that make this possible.

That means listening carefully, understanding the site, selecting an appropriate approach and considering what support may be needed once a system is operating.

Landscape representing responsible resource use and sustainable planning
How we work

A clear process, shaped around your requirements.

01

Understand

We begin with your needs, site conditions, source water, energy requirements and intended outcomes.

02

Assess

We consider the practical requirements and the technologies that may be appropriate for the application.

03

Design

We develop a solution around the specific requirements rather than assuming one product fits every situation.

04

Support

Where agreed, we provide remote monitoring, operational oversight and reporting for plants in our care.
