The advantages of the remarkably simple MOST system are how well it works and how little maintenance is required.

The system uses no moving parts *, with the exception of a high reliability, purpose-built air blower, which delivers fresh air into the heart of the treatment. This source of oxygen-rich and self-cleaning air provides the perfect environment for natural 'friendly' bacteria to grow, multiply and treat the waste water.

• Local council and regulatory requirements may require additional pumping and irrigation systems.

The treated water is clear, odourless and can be reused on site (subject to local authority approval) for applications such as watering the garden, car washing, toilet flushing. Optional modules include membrane filters, UV sterilisation and biological nutrient filters to increase treatment quality as required.

EarthSafe MOST systems are modular, scalable systems, manufactured by EarthSafe and delivered as a complete package for installation on-site. The most popular Advanced ES10DGTS model is housed in a single concrete tank, with adequate capacity to treat applications of up to 10 persons.

EarthSafe's standard Advanced ES10DGTS system has been designed to achieve a 95% reduction in BOD₅ and Suspended Solids. Additional sterilisation will reduce Faecal Coliforms to virtually zero. Where required, an optional EarthSafe biofiltration module can be fitted to reduce nutrients, such as nitrogen and phosphorous.

The ES10DGTS system is accredited by NSW Department of Health (approval #DGTS002) and has been designed to conform with Australian Standards AS1546.3.2008 and AS1547.2000.

Once the choice is made to use the MOST system, EarthSafe can arrange for further site evaluation, soil and geo-technical reports to be conducted and will take care of all necessary paperwork to submit the application to the local authority.

MOST systems are manufactured by EarthSafe and transported direct to site. Once installation is complete, EarthSafe will commission the system and issue a Certificate of Compliance.

The MOST well-managed system

EarthSafe offers ongoing service and management for every waste water treatment system using a service network of specially trained technicians, the largest in NSW. Each system carries a 20 year warranty on the tanks and a standard 2-year or 5-year extended warranty on the air compressor and tank internals *.

Service and system management for the first 12 months is provided free of charge. At anytime during the first 12 months, customers may take advantage of a 5-year peace of mind service contract, which offers full insurance and extended warranty on all system components.
