Sustainable sewage treatment

Sustainable Sewage Treatment Our sewage treatment plants are designed around two concepts: 1. As little electricity usage as possible.

2. DEWATS (Decentralised Wastewater Treatment) The future for our products and our company is the supply of equipment to homes in countries that currently do not have a sewage infrastructure. Many of these countries have problems with a constant electricity supply so our systems are designed to use little power as possible and most of the small ones don’t use any power at all for the treatment process. As an environmental company we are also very keen to reduce power consumption for ethical and environmental reason and our new products will produce only 10-20% of the CO2 compared to other sewage treatment plants. It also saves the owner money.

Europe and the USA first started installing sewage treatment plants towns and village sin the 1950’s and when the sewage treatment plants were first installed they were correctly sized and worked well. However over the following years the populations expanded and the sewage treatment plants were then too small and didn’t work, this resulted in councils and local government having to build larger sewage treatment plants every 5-10 years to cope with the increasing population, as a result the sewage infrastructure has cost a lot of money and is a never ending project.

One of the biggest problems of a centralised sewage treatment infrastructure is that up to 50% of the costs of treating the sewage is in the pipework, sewers and pump stations required to take the sewage from the house to the sewage treatment plant. This infrastructure has a significant short and long scale cost implication for the council.

The solution to this problem is to decentralise the sewage treatment network so that each property has its own sewage treatment plant.

This concept is called DEWATS. By implementing a DEWATS solution it is the developer that pays for the installation of the equipment and the homeowner who is responsible for the running and maintenance costs of their sewage treatment plants – not the council. This saves the councils millions of dollars over time. It also means that the village/town/city can expand to almost any size because each house is self sustaining.

It also better for the environment for two reasons:  Because owners are directly reasonable for the repair of their system they look after it better than if they were connected to a municipal system.  In a centralised plant a single failure can result in a large pollution incident however in a decentralised network it would take multiple, simultaneous failures to achieve the same scale pollution event.

With a DEWATS solution the cost of transporting the wastewater from point of creation to the point of treatment does not exist so neither do the installation, maintenance and replacement costs of the pipes and pumps need to transport the wastewater in a centralised system.
