Sump Project
A Sump is used as additional storage at the village/town level or cluster level. It is not used for the direct distribution of water. Rather, it is used as intermediate or contingency storage, to store water before it is pumped to ESR/GSR. The underground storage tank in a circular shape with a dome line covering is called a sump. Generally, the capacity of the sump is more (one and a half to two times) than ESR or GSR or two to five days water requirement, so that if the supply is disturbed for that time, the water is available for the people.
A sump pump is a pump used to remove water that has accumulated in a water-collecting sump basin, commonly found in the basements of homes. The water may enter via the perimeter drains of a basement waterproofing system, funneling into the basin, or because of rain or natural groundwater, if the basement is below the water table level.
Sump pumps are used where basement flooding happens regularly and to solve dampness where the water table is above the foundation of a home. Sump pumps send water away from a house to any place where it is no longer problematic, such as a municipal storm drain or a dry well.
Water Tank Project
Distribution storage tanks, familiar sights in many communities, serve two basic purposes: equalizing storage and emergency storage. Equalizing storage is the volume of water needed to satisfy peak hourly demands in the community. During the late-night and very early morning hours, when water demand is lower, high-lift pumps fill the tank. During the day, when water demand is higher, water flows out of the tank to help satisfy the peak hourly water needs. This allows for a uniform flow rate at the treatment plant and pumping station. Water in a distribution storage tank may also be needed for fighting fires, cleaning up accidental spills of hazardous materials, or other community emergencies. The capacity of a distribution storage tank is designed to be about equal to the average daily water demand of the community.
Distribution storage tanks are built at ground level on hilltops higher than the service area. In areas with flat topography, the tanks may be elevated aboveground on towers in order to provide adequate water pressures, or ground-level storage tanks with booster pumping may be provided.
Pipe Line Project
The pipeline system of a municipal water distribution network consists of arterial water mains or primary feeders, which convey water from the treatment plant to areas of major water use in the community, and smaller-diameter pipelines called secondary feeders, which tie into the mains. Usually not less than 150 mm (6 inches) in diameter, these pipelines are placed within the public right-of-way so that service connections can be made for all potential water users. The pipelines are usually arranged in a gridiron pattern that allows water to circulate in interconnected loops; this permits any broken sections of pipe to be isolated for repair without disrupting service to large areas of the community.
“Dead-end” patterns may also be used, but they do not permit circulation, and the water they provide is more susceptible to taste and odour problems because of stagnation. A water distribution pipeline must be able to resist internal and external forces, as well as corrosion. Pipes are placed under stress by internal water pressure, by the weight of the overlying soil, and by vehicles passing above. They may have to withstand water-hammer forces; these occur when valves are closed too rapidly, causing pressure waves to surge through the system. In addition, metal pipes may rust internally if the water supply is corrosive or externally because of corrosive soil conditions.
Machinery Pumping Service
Our professionals hold expertise in providing Pump House services to clients. These pump house services are carried out using premium grade raw material and the latest advanced machinery. These pump houses find application in the transformation of water, chemical, and a variety of other fluids.
Many kinds of pumps are used in distribution systems. Pumps that lift surface water and move it to a nearby treatment plant are called low-lift pumps.
These move large volumes of water at relatively low discharge pressures. Pumps that discharge treated water into arterial mains are called high-lift pumps. These operate under higher pressures. Pumps that increase the pressure within the distribution system or raise water into an elevated storage tank are called booster pumps. Well pumps lift water from underground and discharge it directly into a distribution system.
Most water distribution pumps are of the centrifugal type, in which a rapidly rotating impeller adds energy to the water and raises the pressure inside the pump casing. The flow rate through a centrifugal pump depends on the pressure against which it operates. The higher the pressure, the lower the flow or discharge. Another kind of pump is the positive-displacement type. This pump delivers a fixed quantity of water with each cycle of a piston or rotor. The water is literally pushed or displaced from the pump casing. The flow capacity of a positive-displacement pump is unaffected by the pressure of the system in which it operates.
Government Building Projects
Sarva Shiksha Abhiyan (SSA) is a comprehensive and integrated flagship programme of the Government of India to attain Universal Elementary Education (UEE), covering the entire country in a mission mode. SSA was launched in 2001-2002 in partnership with the State Governments and Local Self Governments. The programme aims to provide useful and relevant, elementary education to all children in the 6 to 14 age group by 2010. It is an initiative to universalize and improve the quality of education through decentralized and context-specific planning and a process-based, time-bound implementation strategy. The programme lays emphasis on bridging all gender and social category gaps at the elementary education level with time-bound objectives.
