WASTEWATER MANAGEMENT
Waste water is residual water discharged from households, industries or other public places which generally contains materials or substances that can be harmful to human health and disturb the environment.
Another limitation says that wastewater is a combination of liquid and liquid waste originating from residential, commercial, office and industrial areas, together with groundwater, surface water, and rainwater that may be present (Haryoto Kusnoputranto, 1985).
Waste, garbage, and sewage originating from households, companies, and/or vehicles are serious problems that need attention to create environmental health. Disposal of household waste is accustomed to trash bins, therefore trash bins should always be available in the residential environment according to its type, wet waste (garbage), dry waste (rubbish), and industrial waste (industrial waste).
In addition, the habit of spitting, urinating and defecating (human excreta), wastewater (sewage) must also be managed properly so as not to interfere with environmental health. Garbage that is not managed properly can become a breeding ground for animals that spread disease and unpleasant odors.
Although it is residual water, the volume is large because approximately 80% of the water used for daily human activities is disposed of again in a dirty (polluted) form. Furthermore, this waste water will eventually flow into rivers and seas and will be used by humans again.
Therefore, this waste water must be managed and/or treated properly whit wastewater treatment plant. This wastewater comes from various sources, broadly it can be grouped into the following:

- Waste water sourced from households (domestic wastes water), namely waste water originating from residential areas. In general, this wastewater consists of excreta (feces and urine), water used for washing kitchens and bathrooms, and generally consists of organic materials.
- Industrial waste water (industrial wastes water) originating from various types of industries due to the production process. The substances contained in it vary greatly according to the raw materials used by each industry, including: nitrogen, sulfides, ammonia, fats, salts, dyes, minerals, heavy metals, solvents, and so on. Therefore, the treatment of this type of wastewater becomes more complicated because it must consider its impact on the environment.
- Municipal waste water is waste water originating from offices, trade, hotels, restaurants, public places, places of worship, and so on. In general, the substances contained in this type of wastewater are the same as household wastewater.
