Construction sites are major centres of soil, water, air and noise pollution. The construction industry is responsible for about 4% of the total particulate matter emissions. It also has a huge water requirement along with other raw materials and a huge quantity of water which is discarded is not reusable. The construction of walls, plasters, structures and maintenance and repairs of the same requires a humongous quantity of water.
It is the severity of this problem which has led to an increase in demand for alternative solutions as countries can no longer ignore the adverse effects leading to water shortage. Waterless construction is an alternative encouraged by construction material suppliers such as Green Build Products. It is preferred to the traditional methods for curbing water pollution by huge margins as they reduce the water demand for the construction projects.
Water Pollution and Construction Industry
Any addition of contaminants which degrades the quality of water bodies is caused by the unfiltered discharge of pollutants and is known as water pollution. The ground water can become polluted due to leaching of chemicals used. Paints, cement, volatile organic compounds, glues, oils and other chemicals are discharged from a construction site. These discharges pose a major problem if mishandled and discharged without proper precautions. The impacts that these unfiltered discharges have are:
- High risk of flooding and blockage of drains as the silt in wastewater can block the drainage systems by accumulation.
- The silt and sand that are released accumulate in water bodies where they enter the gills and block it causing respiratory distress and ultimately death of aquatic organisms.
- The muddy colour imparted to the water bodies is a visual annoyance.
- The immediate effect of the discharge is increased turbidity of water bodies.
- Pollution of surface water in the surrounding area which causes diseases in animals who drink it.
An apt choice for curbing water pollution is to adopt waterless construction which reduces the depletion of water resources and the demand of water from construction sites. Waterless construction products are usually made from recycled substances which are then made available for use as ready to use polymerized pastes which do not even need wetting. These products are reliable as they have high compatibility with any form of construction and enhanced durability. Apart from contributing to the ecosystem as a whole, they also reduce the dependence of a construction site on water which leads to faster completion of work to meet specified deadlines.
Role in curbing pollution
Waterless construction plays a critical role in curbing water pollution as it reduces the on-site usage of water.
- Reduces the amount of pollutants discharged into the soil and hence, the groundwater significantly.
- Non-hazardous waste which do not contribute to surface water pollution.
- Removal of extensive water source to stop dust and particulate matter from spreading.
- No sludge is produced which removes the need to process a large amount of disposable water waste.
- Does not pose as a threat to aquatic life as there is comparatively very little or no water requirement.
To wrap up
In the era of eco-friendly technologies, waterless construction is a blessing which serves the ecosystem. Reduced water usage decreases the pressure on natural resources and contributes to a healthy living.
