The word sewerage is made from sewer. The word sewer indicates the usable water which is received from kitchen, bathroom and outfall from toilet/W.C. Every large or small city was held at sea, river and lake and it was planned at initial stage of the project planning, that the dirty water of homes and industries was dumped in that water source easily. Many years passed the dirty water from these utilities are dumped in the nearest source and that source water was make too poisons. Many aquatic life is survive in water and when dirty water is mixed with water source the biological cycle was affected and fishes and other animals population was decreases. Image Source:Pexels.com In that case population of human is also increases continuously and after that level of water source was decreases and we faced many problems continuously. Then sewer network is introduced. Outlet from all homes are connected to lateral lines means the water of kitchen, bathroom and water closet are co

When the energy received by earth from the sun is known as “solar energy”. Solar energy is comes under renewable energy. Solar radiation is the utilized by the solar plates for further use. The working procedure of solar system is capture, convert and then distribution. Image Source:Pexels.com Solar system is categorized in two parts:- (1.)   Passive Solar: -   In this system the selected material have light dispersion properties and designing spaces that the circulate air naturally. This system reduces the need for alternative resourcs and generally focuses on demand side technologies. (2.)   Active Solar:- This system is based on photovoltaic modules (i.e. also known as photovoltaic panels) and collectors of solar thermal system to convert sun light into their useful output. Its increases the supply of energy. Image Source:Pexels.com Recent Post: Different energy sources Working Procedure:- In this system with the use of photovol
