Design of Water Distribution System by using JalTantra Software

Abstract

Design of pipe distribution networks for villages require considerations toensure that the system is effective and sustainable. Water distribution network is a system of engineered hydrologic and hydraulic components which supplies water from the source to the requiredarea. In the design ofa waterdistributionnetwork, itis crucial that the network supplies the forecast-ed demands with enough residual heads at all nodes of the network during the entire design period. However, with the increasing change in future scenarios, either the nodal demands change or the water distribution network falls short to meet the increasing demands. Therefore, we require a proper analysis of water networks to strengthen them for the future. In situations like this, software plays a major role in analyzing water distribution networks to make it work as per the design. The present study is an effort to analyze the water supply network using available software, it proposes hydraulic simulation model for water distribution network analysisand comparison of results.

Introduction

The document discusses the design and implementation of a water distribution network using JalTantra software, with a focus on Kotewada village in the Nagpur district of Maharashtra, India. It highlights the importance of using modern tools for designing efficient, reliable, and cost-effective water supply systems, especially in rural areas where access to clean water remains a challenge.

Key Highlights:

1. Importance of Water Distribution Networks

• Ensure efficient delivery of clean drinking water to households.

• Reduce reliance on unsafe water sources like wells or ponds.

• Improve public health, particularly by preventing waterborne diseases.

• Save time and effort, especially for women and children who traditionally collect water.

2. JalTantra Software

• A web-based hydraulic modeling and analysis tool developed for designing and optimizing water networks.

• Assists in sizing pipes, tanks, pumps, and valves.

• Especially useful for gravity-fed systems where electricity is unreliable.

• Enables accurate simulation and optimization of water distribution systems.

3. Case Study: Kotewada Village

• Location: Hingna Taluka, Nagpur District, Maharashtra.

• Population: 1,496 (as per 2011 Census).

• Current water sources: Public wells and Elevated Storage Reservoirs (ESRs).

• Challenges: Insufficient water supply and reliance on manual water collection.

4. Objectives of the Project

• Ensure reliable and equitable water supply.

• Optimize energy use and minimize water losses.

• Build resilient infrastructure with low maintenance costs.

• Perform cost analysis to reduce both construction and operational expenses.

5. Methodology

A. Area of Study

• Kotewada was selected due to its water scarcity and urgent need for a pipe network.

B. Data Collection

• Collected data includes:

  • Network layout (pipes, tanks, pumps)

  • Topography (elevation, terrain)

  • Water demand (domestic and other uses)

  • Water source characteristics

C. Data Analysis Using JalTantra

• Inputs data to model the water network.

• Conducts hydraulic simulations to optimize pipe sizing and pressure levels.

• Generates visualizations and simulations of the entire pipeline system.

D. Village Survey

• Field data collected using instruments like Dumpy Level and Level Staff.

• Measurements used for mapping node-to-node distances in the network.

6. Necessity & Benefits of a Pipe Network

• Efficient transportation of clean water.

• Versatile and scalable for future demand.

• Safe with built-in features like backflow preventers and pressure valves.

• Cost-effective and flexible to changing needs or expansions.

Conclusion

Water Systems is an innovative water distribution management Software that optimizes and manages water distribution systems, and enables real-time monitoring of water quality data. 1) Population Forecasting Methodology: After a comprehensive analysis of various population forecasting methods, it is evident that theGeometric IncreaseMethodis themostsuitablefor the designpurposesinthisscenario.Theforecasted population of 2000, derived from this method, is recommended due to same percentage increase across decades. 2) Elevated Storage Reservoir (ESR): The Mass Curve Method has been applied to determine thecapacity ofthe ElevatedStorage Reservoir (ESR), resultingina capacity of 1,60,000liters. This capacity ensures that there is ample water storage to meet the projected demand and maintain water supply standards for the designated area. 3) Pump: The Pump selected is a Non-self-priming centrifugal Monoblock Pump of Power 2 HP and in case the main pump faces any operational issues, a standby pump with identical specifications will be activated.
