Pakistan is on its way to become a water deficient country as it already stands at 30th position among the most water-deficient countries of the world. Safe drinking water is one of Pakistan’s most immediate and crucial problems that demands earliest actions to be taken for its resolution.
Alkhidmat Foundation Pakistan is practically active to ensure the provision of clean drinking water by installing hand-pumps in arid lands, drilling water-wells in remote water-scarce areas, installing water-filtration plants in cities, and supplying water to homes in villages through its water schemes. Alkhidmat Clean Water Program takes every possible measure according to the needs of the water-scarce regions to implement its mission.
Small Hand Pump
In remote areas of Pakistan, most of the people mainly rely on open water which is contaminated and unhygienic. This practice results in the spread of disease such as cholera, typhoid and dysentery. In flat fertile areas small hand pumps are ideal source to get clean drinking water for households. Moreover, suction hand pumps are cheap, easy to install and maintain.
Small Hand Pump is a conventional lever action hand pump. It is designed for serving communities of up to 150 individuals. These hand pumps are fully corrosion resistant, easy to install and has excellent potential for community-based maintenance.
Community Hand Pump “Afridev”
The Afridev Pump is a conventional lever action hand pump. It is designed for heavy-duty use, serving communities of up to 300 individuals. The Afridev Pump is fully corrosion resistant, easy to install and has excellent potential for community-based maintenance.
This pump is also known as the Deep-well piston hand pump. Community hand pumps are ideal for villages and households in which surface sources are common, so only a basic pump suffices for communities trying to meet their water requirements. Suction hand pumps are economical, easy to install and maintain. Maintenance is done at the village level without the need for specialist parts. The pumps are made from cast iron.
Community Water Well
It is a traditional source of water in rural areas of Pakistan. Earth is excavated deep to fetch water. Digging is done through various techniques including drilling, blasting etc. Cemented rings are put in open wells for long life and sustainability. Water motors and hand pulleys are used for pulling the water up, down from the wells.
Submersible Water Pump with Water Storage Tank
A submersible water pump operates beneath the earth’s surface. Submersible Water Pump pushes water to the surface. Most submersible pumps are long cylinders that are about 3 to 5 inches’ diameter and 2 to 4 feet long. Submersible Water Pump have a hermetically sealed motor that is close-coupled to the body of the water pump. Having a hermetically sealed motor prevents the water from getting inside the pump’s motor and causing a short circuit.
Other components of a submersible water pump are the cable, which is connected to the motor and a pipe that transports the water to the surface. Water is then stored in water storage tanks constructed nearby Submersible water pump.
Submersible Water Pump projects are best suitable to run systems for water pumping in remote areas or where electricity has frequent outage.
Solar Submersible Water Pump with Water Storage Tank
Water pumping is generally dependent on conventional electricity. Solar pumping systems are environment friendly and require low maintenance with no fuel cost. Keeping in view the shortage of electricity in Urban, rural and remote areas in many parts of Pakistan, Solar power pumping is one of the most promising applications using solar energy. The technology is similar to conventional water pumping system i.e. electrical submersible water pumping except that the power source is solar energy. Solar Submersible water pumping technique is gaining importance in recent years due to non-availability of electricity. The flow rate of pumped water is dependent on incident solar radiation and size of PV array. A properly designed PV system results in significant long-term cost savings as compared to conventional pumping systems. In addition, tanks can be used for water storage in place of requirement.
Solar Submersible Water Pumping are best suitable to run systems for water pumping in remote areas or where electricity has frequent outage.
Water Supply (Gravity Flow Scheme)
The distribution of water is always troublesome in hilly and remote areas. To remedy the situation a reservoir of water is created mechanically and stored at a place where it could be easily disseminated to the required population. The scheme also involves the development of new water resources so that demand could be met along seamless provision lines
Water Filtration Plant
Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from contaminated water. The goal is to produce water fit for drinking purpose. Water purification plants are the source of providing pure, safe, and healthy drinking water to people. Water filtration plants make use of “Reverse ‘Osmosis processes for water purification
Reverse Osmosis (RO) process is used on those areas where underground water condition is very not good i.e. Water is Saline.
