From Intermittent to Continuous Water Supply in Amravati City
The key objective of this initiative is to transform the water supply system in the city from intermittent supply to continuous (24X7) water supply system. The Maharashtra Jeevan Pradhikaran (MJP) has implemented 24X7 water supply in two zones of Amravati on pilot basis in Sai Nagar and Arjun Nagar through holistic approach addressing policy, technical, organizational and financial aspects. A key feature of the initiative is to adopt a 'whole to part' approach by first developing a hydraulic model for the whole city and then implementing the 24X7 water supply in two pilot zones and extend to entire city.
Population of Amravati City was 5,49,150 (Census 2001) and area within municipal limit is 121.65 sq. Kms. Present population of the city is about 7 Lakh. MJP has proposed to implement 24X7 water supply in the entire city to attain public health benefits by adopting a hydraulic model for the entire city and then implementing 24X7 in two zones on a pilot basis.
Prior to the initiative, the water supply was only for three hours a day with low pressure. The Non-Revenue Water (NRW) was quite high and the incidence of water borne diseases was also high. The number of complaints related to water supply was also more.
The key objective of the initiative is to move from intermittent supply to 24 X7 water supply. Other objectives include:
- Reduction in NRW from 54 percent to 15 percent
- Reduction in staff required to operate valves in a intermittent supply
- Improving the distribution management
- Reducing the wastages from storage and throwing of stored water in an intermittent system, identifying illegal connections and reducing public stand posts
- Improving the quality and pressure
- Reducing customer complaints
- Achieving better and improved consumer satisfaction
The 24X7 water supply initiative in Amravati was implemented through a step by step process A quick bird satellite image with digital map of road network and properties with 0.5 resolution was procured from the National Remote Sensing Agency (NRSA), Hyderabad. The satellite image was superimposed with the GIS map and used as a backdrop for hydraulic model. For the purpose of pressure management in the distribution system, a stereo paired satellite image with contours of the city was developed.
Water supply system of Amravati was simulated by creating a hydraulic model by a software called WaterGem. A dedicated Change Management Unit (CMU) was constituted comprising MJP officials for the purpose. Holistic capacity building of CMU was undertaken and this has enabled the MJP to develop the biggest hydraulic model of the country in-house. A comprehensive consumer survey covering 101,723 properties having 65,930 connections was conducted and the work was outsourced to the M/s ADCC Info Cad Pvt. Ltd.
After developing the hydraulic model for the entire city, the 24X7 water supply in the pilot zones of Sai Nagar and Arjun Nagar was commissioned. For the purpose District Metered Areas (DMAs), were created and bulk meters were installed.

The scheme is implemented through a hydraulic model which is the biggest hydraulic model in water supply in the country covering 2,900 nodes and pipelines. The scheme has employed innovative tools such as GIS maps and household surveys and hydraulic modeling quite effectively.
Regular communication with political representatives and media has ensured wide stakeholder participation. Along with technical innovations, financial innovation such as identification of illegal connections, removal of Public Stand Posts (PSPs), revision in tariffs and adoption of block tariffs have resulted in full Operation and Maintenance (O&M) cost recovery with surplus. The benefits exceeded the costs by improving the access and quality and cost recovery as well.
The key outcomes and impact are as follows:
- The initiative has resulted in 24X7 water supply in two pilot zones Sai Nagar and Arjun Nagar of Amravati
- The initiative has resulted in significant reduction in NRW. The NRW has reduced from 51% to 33% in Arjun Nagar and from 37% to 25% in Sai Nagar.
- The water consumption has also reduced from 1.98 MLD to 1.48 MLD in Arjun Nagar and 1.81 MLD to 1.61 MLD in Sai Nagar.
- 6 PSPs were removed from Arjun Nagar and around 60 slum households were given individual connections.
- The initiative has resulted in increased coverage and access, quality, reduction in water borne diseases and reduced customer grievances
- The initiative was implemented completely by utilizing the in-house expertise. This has resulted in cost effectiveness
- The initiative has successfully demonstrated the role of GIS and hydraulic modeling and also highlighted the significance of 'whole to part' approach.
- The initiative has adopted innovative IEC campaign
- Water supply pressure has improved considerably to reach up to the second floor. As a result the customers need not use electricity for pumping water to their overhead tanks.
- There is also no need to store the water and waste the same by throwing.
- The initiative has resulted in increased consumer satisfaction.
- The initiative has resulted in increased cost recovery.
- It is also reported that the incidence of water borne diseases has come down in both the zones as the quality of water improved.
