In 2007, on the recommendations of the International Water Management Institute, the Indian government allocated ₹ 1,800 crore (equivalent to ₹ 54 billion or US$630 million in 2023) to fund dug-well recharge projects (a dug-well is a wide, shallow well, often lined with concrete) in 100 districts within seven states where water stored in ...
High water tables (in some cases less than 1 metre below the surface) and poor ground conditions have meant that the local water company, Anglian Water, has embraced the use of vacuum sewerage, taking advantage of the system's requirement for small bore sewer pipes laid in shallow trenches, dramatically reducing the requirement for pumping ...
A sewer pipe is normally at neutral air pressure compared to the surrounding atmosphere.When a column of waste water flows through a pipe, it compresses air ahead of it in the system, creating a positive pressure that must be released so it does not push back on the waste stream and downstream traps, slow drainage, and induce potential clogs.
Experts share how to prevent your pipes from freezing this winter ahead of freezing temps and holiday travel plans, as well as what to do to thaw frozen pipes.
Shut off the water supply. If your water leak detection system has already gone off or your pipes have burst, turn off the water at the main shutoff valve in the house.
The frost line—also known as frost depth or freezing depth—is most commonly the depth to which the groundwater in soil is expected to freeze. The frost depth depends on the climatic conditions of an area, the heat transfer properties of the soil and adjacent materials, and on nearby heat sources.
Deep well pumps extract groundwater from subterranean aquifers, offering a reliable source of water independent of municipal networks. These pumps, often submersible and powered by electricity, can access water reserves located much deeper than shallow wells, ensuring a consistent supply even during periods of drought.
Days of freezing temperatures in Deep South areas that usually freeze for only hours are threatening dozens of water systems as burst pipes leak millions of gallons of water. The problems were ...
