The vast land of Iran is a climate rich in valuable resources, many cities and settlements, and hardworking people. Our ancestors have long been aware of their living conditions, defined the form of life in accordance with it, and tried their part in exploiting the resources and facilities, in accordance with the climatic conditions of cities and villages. Thanks to the ingenuity of its inhabitants and the intelligent management of limited water resources, Iran's low rainy climate was still suitable for living, and even in the rainy and dry seasons, farmers, landowners, and villagers enjoyed the blessings of refreshing water thanks to the Moghans. As the invention of the aqueduct or in other words karez was one of the inventions of Iranians and was introduced to other parts of the world. \ R \ n \ r \ nIn recent years due to significant population growth, climate change and disregard for the principles of water resources management, Rainfall in the sky has taken on a different form for the inhabitants of this land and poses a security threat. \ R \ n \ r \ n For decades, in many countries of the world, whether those in their regions are at risk of dehydration And those in lands rich in reliable water resources, effective programs are developed and implemented to manage water resources and maintain environmental health. One of them is wastewater management. \ R \ n \ r \ nWastewater management is a mandatory plan in all communities because of the many adverse environmental effects and threats to human health from the lack of a proper collection and treatment system. Sewage has been proven. Each cubic meter of raw sewage released pollutes 40 times its volume of groundwater and surface water 1 and this pollution, in addition to environmental hazards in rivers, wetlands and lakes, with the interconnected interdependence of human life with nature in the short term It has a very negative impact on human health. \ R \ n \ r \ nOn the other hand, sewage as a fluid that is 99.9% water is a potential source of water reuse. Today, wastewater treatment technology has made it possible to use it even in drinking cases. Use of colorless and odorless treated wastewater in agriculture, irrigation of green spaces, cooling towers, water required in industries, water required for construction activities, flash tanks for sanitary services, car washes, area washing, etc. Has provided us with a new and reliable source of water. \ R \ n \ r \ nClimate Wastewater Engineering Company (Private Joint Stock) as a consultant and executor of environmental projects, relying on the technical knowledge of its experts and specialists and knowledge And modern technology, focusing on wastewater treatment through treatment packages as a way to protect the environment and manage the use of water resources, as well as suppliers of industrial, semi-industrial and domestic water treatment systems as a step towards improvement. Community Health intends to take small but effective steps to improve the risk of dehydration as well as to manage the challenging relationship between water and human health. \ R \ n \ r \ n We are proud to be concerned about the well-being of our country.
