Pollution is a major issue faced by urban communities around the globe. Whether it is in the form of air, land or water pollution the phenomenon affects our lives in several ways. The rising cases of asthma, poor quality of food grains, fruits and vegetables and spread of water-borne diseases are just some of the effects of pollution.
Development with harmony
Cities all over the world are grappling with not enough hygiene and sanitation facilities due to poor infrastructure planning. Generally the available resources and facilities show to be insufficient to support the growing population.
Urban increase in harmony with the environment is an important aspect of town planning a thing that is often overlooked generally in most places. A well planned settlement with facilities for water treatment for both potable purpose as well as recycling makes for fitness. Industrial units, one of the main sources of water pollution should be away from residential zones with facilities to take care of effluents and exhausts.
The benefits of Water treatment
Recycled water has been utilized to great benefit for agriculture and landscaping purpose. In coastal areas or places where the rainfall is heavy, storm water and rain water treatment systems have given large amounts of water to communities for use for a variety of purposes from residential hygiene associated with large scale irrigation.
Advanced technology with traditional means
Several urban and semi-urban areas have extensive water treatment facilities which make use of sophisticated filtration systems. These systems are usually based on up to three levels of purification based on physical, chemical and biological processes. The physical filtration method is based on traditional means using sand, pebbles and sediment chambers. Advanced filtration processes include materials like active carbon, ion-exchange process, artificial and biological membranes and stuff like that.
The water treatment system was used extensively in most places on a large scale as well as for domestic purpose. Entire cities are with water treatment plants situated at various places. Small water purifier units observed in many households use the same filtration technique albeit over a small scale.
Health is wealth
Water purification units for potable purpose also take advantage of additives like chlorine and water softeners along with the other methods. Storm water runoffs have become systematically collected in tanks and treated in plants for use for flushing toilets, watering trees as well as on croplands. This has reduced the prevalence of diseases like malaria which occur as a result of stagnant water. Also the incidence of other water borne diseases too has reduced considerably in places where water treatment plants have been set up.
Often along with financial constraints, lack of knowledge, awareness and infrastructure result in degradation of the environment. Most town planning authorities have tried to resolve the problem by allocating a separate fund for environmental concerns within maintaining public health insurance hygiene.
