Sewage Systems

The treatment of sewage also called wastewater, it the removal of contaminants from both household sewage and wastewater. This can be done via physical and chemical forms, the aim of either is to either remove the sewage or make it into a form that is able to be reused and put it back into the environment.

Sewage is made up for both waste liquids from households, for example toilet and shower waste, but also waste liquid from industries. Once the waste is gathered it is separated into greywater and blackwater. Greywater is the recycle and used for things like toilet water or for watering pants. Unlike blackwater which contains more toxic substances which therefore means it can't be recycled.

There are also sewage systems called combined sewage systems, which collect both sanitary wastes from households and industries, but they also collect the rain water. Where these combined sewers where popular in the early days as they allowed a single pipe system for both forms of waste therefore making it less expensive for companies and governments that needed both forms of sewers. However they cause problems as it is both difficult to separate the two forms of waste and they are also prone to over flow.

Sewage treatment areas are normally away from towns in order to protect the health of the general pubic, stopping any diseases. The treatment of sewage helps to also prevent water pollution. Sewage can also be collected by using a vacuum system which uses a small amount of pressure through a grinder pump through a point of connection of the sewer. These vacuums are useful as they can go through this process for up to 1,200 homes before they start to cost more than a treatment plant.

If your existing sewage treatment systems are not achieving your required standards then consider fitting a retro unit to bring your system back to an approved discharge standard.

The industry recognised training for individuals with construction site management accountability or a business providing services to construction or civil engineering sites is the CITB SMSTS (Site Management Safety Training Scheme).

A dust extraction unit is used in industry, schools and colleges to improve the breathable air quality by removing particles and matter from the air and environment.
