Water Quality Solutions for Jal Jeevan Mission

Jal Jeevan Mission aims to provide safe tap water to all rural Indian households, focusing on source sustainability and community involvement. It promotes water quality through monitoring, digitalizing the entire rural water supply for transparency and grievance redressal.

Solution Overview

  • Our solutions include accurate and user-friendly water testing instruments, chemistries, and software.
  • We offer innovative analytical instrumentation designed to meet the specific needs of rural communities.
  • Our mission is to ensure reliable and sustainable access to safe drinking water for every household.
  • With Hach's support, the Jal Jeevan Mission can achieve its goal of providing potable water to all rural areas in India.

The Challenge

Source Water

Source Water


  • Premature exhaustion of source (drying up of source)
  • Poor raw water quality
  • Pump assembly failure or insuffcient intake by pump
Water Treatment

Water Treatment


Insuffcient water output (quantity) or poor-quality water produced

Water Pipeline and Storage

Water Pipeline and Storage


  • Pump assembly failure
  • Overflowing/empty storage unit (e.g., ESR)
  • Frequent leakages and difficulty in detecting minor leakages; inadequate pressure in pipe
Water Distribution Network

Water Distribution Network


  • Inconsistent service delivery (outages, quality, low pressure, hours of supply)
  • Irresponsible/excess usage at household (HH) level; unauthorized connections resulting in high NRW

On-Site Challenges

  • Most of sites are powered by Solar, which makes water supply only during daytime.
  • Drinking water schemes under JJM are typically having water supply for few hours in a day (typically 2 – 6 hours/day). Frequent failure of Pump Assembly ,this leaves no flow condition for several hours in day.
  • Ground Water Contaminations
  • Calibration of equipment’s related to WQMS and poor Laboratory Infra.
  • Scattered Site Locations.
  • Timeline Management.
On-Site Challenges
Challenges in Monitoring chlorine

Challenges in Monitoring Chlorine

  • As water supply is only for few hours in a day, no flow condition is significant challenge for Chlorine monitoring in amperometry method.
  • No flow condition will cause Chlorine sensor deuteriation and needs early replacement of sensor.
  • Also, Chlorine sensor requires warm up time when water supply restored during next day. Stabilization of readings will take at least 30-90 minutes.
  • As nature of Amperometry method, monitoring depends on sample pH, Temperature, Flow and pressure. All these sample conditions will impact measurement.
  • Due to above Chlorine sensors using Amperometry method

The Solution

The initiative emphasizes public access to water quality data and alerts local authorities for prompt remedial action, ensuring effective policy implementation for assured service delivery. Chlorine and Turbidity are vital parameters for ensuring water safety before distribution. These parameters are monitored through online analyzers, which control Chlorine dosing and transmit data to the cloud via RTU for centralized management. To ensure a decade of reliable operation, it's crucial to choose online analyzers from reputable manufacturers with established facilities and high-quality standards.

The Results

Hach provides the right instruments for water quality testing, offering low maintenance and high reliability for remote operation.

Portable Pocket and Handheld Colorimeters

HACH's Colorimetric method for Chlorine is the best suitable method for JJM projects due to:

  • BIS Approved Method as per BIS standard ISl0S00 for drinking water quality
  • Eliminates need for measuring pH for compensation as reagent has pH buffer to bring sample pH to 6.3 to 6.6pH.
  • No calibration required for the lifetime of the Chlorine analyzer
  • Good agreement with Lab results
  • Predictive Diagnostics and low maintenance
  • Optimal Chlorine Dosing
