Overview: Filtered Drinking Water Project at Ahom Pathar, Assam
Safe drinking water access is a fundamental human necessity and a basic human right. All people’s physical and social health is put at risk by contaminated water. Approximately 15% of Indians use open defecation, while more than 6% of the population lacks access to clean water.
Such is the case for Ahom Pathar, a tribal village in Assam.
Small-town Sorbhog is located in Assam. The town has several dispersed tribal settlements. Ahom Pathar is one such community. There is a severe power outage and a stable grid in the hamlet. As a consequence, the present water treatment plant is no longer able to operate, and the only option to get it back in working order was to upgrade the Pipe Water Supply Scheme under the Functional Household Tap Connection and restore them.
The following issues plagued the neighborhood’s development of a drinking water system:
- The location was in a poor condition. Due to the single-phase rather than the three-phase line being used, the water filtering facility was not functioning.
- Voltage fluctuations, faulty installation, and lightning all contributed to the electrical system’s failure.
- Broken pipe, particularly in the valve portion, was caused by improper plumbing.
- Due to poor choice of pumps- a single 3 HP submersible & a single 3 HP surface pump unreliable power supply to the village.
Implementing the project was a challenging challenge. All of the plumbing, electrical, filtration, and pump systems must be repaired in order to get the water system back to working order. With the site’s challenging terrain, lack of sufficient area, and short sunshine hours, SunShell Power embraced the challenge and developed a workable method to restart the pump house.
Our Solution: As a result of thorough discussion with the PHED and the contractors, the decision was made to install a 3HP five-inch bore-well submersible pump, powered by 10 no. of 335 Wp and a 3 HP open-well submersible pump, powered by 12 no. of 335 Wp solar modules.
The modules were mounted using a single-leg 8-module structure, and the installation site was the backside of the pump house. The lightning arrestor and the Earthing of the plant were fixed, and a remote monitoring system was installed at the site to monitor the data of energy production from the solar modules.
The pumping system, operating o a reserving capacity of 60,000 liters in a reservoir and 30,000 liters overhead tank, is a dual-operated (AC and DC) multi-level protection VFD box.
Because of the successful completion of the project, around 150 families can now drink filtered water, reducing the chances of water-caused diseases. This project also reduced the carbon footprint of the area, maintaining the green environment of the village.
