All You Need to Know about Storm and Wastewater Management

Storm and wastewater treatment

Extreme climate changes, the rise in urbanisation and demographics impact has to lead us to understand that water is the most valuable resource that needs to be conserved.

This practical understanding has stimulated the need to create sustainable water management solutions.

Today, the power of innovation integrated with thorough practical analysis bring to us the best water management solutions solving the water crisis right at your property.

Let us know more about it in detail.

What Is Wastewater?

Wastewater is the water discharged after the use from household, commercial and industrial infrastructures. Wastewater is broadly categorised into Greywater, Blackwater and Stormwater.

Greywater- The usage of water in bathrooms and kitchen for various purposes including washing clothes, dishwashing and other such activities lead to the formation of greywater. This type of wastewater may contain solid impurities, urine, grease and human pathogens. It may also contain kitchen scraps, hair, used detergents, cleaning products, personal care products, oils and other such waste materials that contribute towards the quality of the greywater. Depending on the type of waste released, the greywater may contain a varied amount of phosphates, boron, nitrates that decide the alkalinity and salinity of the same. All these factors pose potential risks to the receiving environment. A more important point to be noted here is that the quality of greywater may get greatly affected if inappropriate disposal methods are practiced at the domestic as well as commercial level.

Blackwater –  The water discharged from toilets is regarded as blackwater. This type of wastewater consists of high amounts of toxic waste due to the presence of fecal matter. As a result, blackwater is concentrated with higher amounts of human pathogens than greywater. Toilet wastewater or waters contaminated by toilet wastewater are both regarded as blackwater.

(As per estimates, a typical household discharges on an average about 95 litres of greywater and 35 litres of blackwater per person each day.)

What is stormwaterStormwater – Stormwater in urban settlements is produced through run-off water from building roofs, paved areas, gardens, roads etc. during rains. Although stormwater cannot be considered as wastewater (logically), management of stormwater is integrated with the wastewater system. The amount of stormwater produced depends on the rainfall and the nature of the surface.

Soiled surfaces can absorb the rainwater effectively compared to impervious surfaces where the production of run-off is always high. The concentration of pollutants and debris in stormwater may correspond to the amount found in greywater. However, this depends on the path through which the stormwater runoff flows. In general, stormwater has lower pollutant load as compared to greywater.

The Impact Of Wastewater On Natural Resources

How does wastewater affect natural resourcesThe impact of wastewater on our natural water resources is substantial. Wastewater comprises a full range of waste materials from liquids to solids. Solid waste materials form sediments and can gradually lead to clogging of drains, water streams and rivers. Nutrients like nitrogen and phosphate can lead to eutrophication threatening the animal life and reducing the oxygen content of the water – this condition degrades the quality of water. Hence, even when the oxygenated wastewater (after treatment) is released into water bodies it still contains nutrients like nitrogen and phosphate that cause eutrophication. And when eutrophic water is further treated for potable supply, it adds to greater costs required for the treatment.

Therefore, In such circumstances, an appropriate methodology that supports sufficient mechanical implementation to reuse the treated wastewater effectively is necessary. Besides, this helps us save money and enhance sustainability eventually amplifying the green footprint of our planet.

Sustainable And Unsustainable Wastewater Management – Which One Is Better?

Living organisms including plants, animals and humans excrete wastes in different forms. These types of wastes are seen in the form of fecal matter, dead biomass, leaf litter and food wastes. The wastewater from urban settlements is treated and released into the water bodies like the lakes, rivers and streams. Yet, when you look at the fresh waters flowing through the natural ecosystem they are as pristine as during their origination. Why? It’s because there exist natural processes that purify the naturally produced waste. This natural system forms the principal basis of the sustainable wastewater and stormwater management in the environment.

However, if the waste accumulation through the release of wastewater exceeds the threshold purification capacity of the natural ecosystem it results in contamination of the water bodies or eutrophication (discussed in the paragraph above). Thus, this factor is responsible for the unsustainable Wastewater Management that is gradually eating away the quality of our natural water resources.

So what could be the ultimate solution to this problem? The answer lies in reusing the wastewater after its appropriate treatment. And that is what we call it as sustainable wastewater management. The wastewater is treated and the nutrients are reused to grow food. This not only keeps our water bodies away from overaccumulation of nutrients but also reduces our need to use chemical fertilizers. Additionally, the treated wastewater can be reused in gardening plants or washing purpose. Precisely, wastewater can be healthily reused in daily activities apart from drinking and cooking.

Furthermore, emphasis needs to be made in keeping domestic wastewater away from the management path of industrial wastewater. And, stormwater should be harvested separately and infiltrated locally.

Integrated Approach To Wastewater Management

In the midst of all this, integrated approach to wastewater management comes out as the best solution. As the name suggests, integrated approach refers to the comprehensive management of wastewater and stormwater. This practice has proved to be beneficial for both commercial and domestic structures.

Integrated wastewater management is a powerful strategy utilised in achieving water sensitive urban design that incorporates entire water cycle into the urban development process. It includes:

  1. Managing groundwater – This improves water supply and consumption efficiency. It also includes an upgrade of the drinking water quality.
  2. Managing surface runoff including stormwater – Investments need to be made for sustainable stormwater management. A wide range of products are available for commercial and residential buildings for stormwater detention.
  3. Managing wastewater – This includes treating the wastewater for its reuse. Domestic, commercial and industrial building infrastructures play a significant role in managing wastewater on-site efficiently. For this purpose, you can find miscellaneous options available on the website.
