Hello! My name is Erin and this is my new energy and environmental care blog. I am a big believer in the responsibility of man to care for the environment. For too long, human beings have brought decay and destruction to the natural world. When I finally moved out of my parent's house last year, the first thing I wanted to do was to make sure my new home was an environmentally friendly as it could be. I called in a contractor who helped me to assess the quality of the soil, to install solar panels and to carry out an energy assessment rating on the property. Since then, my bills have fallen and my carbon footprint has shrunken in size. I learnt a lot during this process which I would like to share here.

You will never know how important water is until you go through a prolonged shortage. Water shortages will impair you from carrying out many productive activities such as farming, mining and construction. Thankfully, the ground has a reliable supply of groundwater that you can exploit and use by drilling boreholes, pumping and treating the harvested bore water so that it is suitable for the your specific use. If you have never drilled one, how will you tell if the borehole has built to the required standards? Well, an evaluation of the basic constituent parts will help you know what to expect when drilling and setting up a borehole:
The Filter Pack
The filter pack comprises clean, smooth, uniform and well-rounded gravel and sand. This section is found between the walls of the well and the borehole. Its purpose is to keep dirt and unwanted material from reaching the borehole's screen. Ideally, sand and gravel made up of smooth uniform particles does a good job of letting water through while keeping larger solids at bay. The filter pack thus plays an important role of keeping the water in your clean for purposes of pumping and ordinary use.
The Well Seal
Just as the name suggests, this part shuts off the borehole from the rest of the world. The seal often comprises a layer of clay, cement or bentonite, and it extends slightly into the inner surface of the well. On the outside, the well seal stands slightly higher than the level of the ground. In this way, it capably keeps off surface runoff from flowing into the borehole and possibly contaminating the pure water that percolates from underground.
The Well Screen
The well screen refers to cylinder-shaped structure installed in all intake areas of the well. The screen is made of metallic pipes with perforations in different sections along its length. During installation, the screens are placed at any sections that carry water into the borehole. Their job is to sieve the water and remove all the dirt before it collects in the borehole. After the water passes through the screens, it is ready for secondary treatment methods like chlorination.
Vadose Zone
For water to rise from deep down the ground to the surface above, then its pressure must be lower than that of the atmosphere. The vadose zone lies between the ground and the water table. Your pipes must reach this zone for you to be able to draw water out of the borehole.
