The Payra 1320 MW thermal power plant is a 1,320 megawatt coal-fired power station built in Kalapara Upazila of Patuakhali District in southern Bangladesh. [1] [2] It is a joint venture between the North-West Power Generation Company Bangladesh Limited (NWPGCL) and China National Machinery Import and Export Corporation (CMC). [3]
A grinder pump (also called a macerator pump) is a wastewater conveyance device. Waste from water-using household appliances (toilets, bathtubs, washing machines, etc.) flows through the home’s pipes into the grinder pump’s holding tank. Once the wastewater inside the tank reaches a specific level, the pump will turn on, grind the waste ...
The Bangladesh Atomic Energy Commission (BAEC) considered building a power plant using VVER-1000 technology or equivalent from other suppliers in 2007, estimating costs between $0.9 billion and $2 billion. [7] By 2009, Russia proposed constructing two units using AES-92 technology, which the government of Bangladesh responded to favorably. [7]
In a typical set-up, a receiving well is provided close to the properties being served so that all sewage can gravitate to the well. An electric macerator pump (also called a grinder pump) pumps the finely macerated sewage through a narrow diameter continuous plastic pipe which discharges into the nearest gravity sewer or treatment plant.
A pumping station is an integral part of a pumped-storage hydroelectricity installation. Pumping stations are designed to move water or sewage from one location to another, overcoming gravitational challenges, and are essential for maintaining navigable canal levels, supplying water, and managing sewage and floodwaters.
Access to an improved source of water supply increased only slightly from 77% in 1990 to 81% in 2010, whereas coverage of improved sanitation increased from 39% to 46% during the same period. [31] As of 2010, 67% of Bangladeshis had a permanent water source and a majority of them used tube wells.
Chopper pumps. A chopper pump is a centrifugal pump which is equipped with a cutting system to facilitate chopping or maceration of solids that are present in the pumped liquid. The main advantage of this type of pump is that it prevents clogging of the pump itself and of the adjacent piping, as all the solids and stringy materials are ...
Bangladesh has been repeatedly exposed to severe flooding. Dhaka was particularly hit by the floods of 1970, 1974, 1980, 1987, 1988, 1996, 1998, 2004, 2007 and 2009, some of which such as the ones in 1988 and 1998 were catastrophic with flood levels of up to 4.5m in parts of the city.
