Transforming Intermittent Water Supply of Developing Countries to 24x7 System</h2><p><strong>Badlapur, India<br>Maharashtra Jeevan Pradhikaran</strong></p><p>Providing
potable water to the dense population of developing countries is a
daunting task. At least 1.6 million people die every year due to
diseases related to unsafe water supply. In India, daily water supply
ranges from just 27 liters per capita per day (LPCD) in poor areas to
160 LPCD in affluent areas – compared to 260 LPCD in the typical U.S.
single-family home. Low consumption is related to poor service provided
by an intermittent water supply. During nonsupply hours, pipes remain
empty and dirty water enters the pipeline at vulnerable spots, causing
contamination and associated health risks.</p><p>When the water supply
source for Badlapur, India, was severely damaged during unprecedented
rain in July 2005, construction of a new barrage gave occasion to
optimize the distribution system for continuous water supply to the
city’s more than 140,000 inhabitants. The <b>project team used WaterGEMS to
design a hydraulic model of existing and proposed pipelines</b>. The
process required modeling the entire distribution system, calibrating
network and consumer withdrawal patterns during system modifications,
and creating zones and district metering areas to further improve
service. Water loss and diversion caused by leaking underground storage
tanks and oversized above-ground tanks complicated the analysis.
Features such as flow controlling valves, reservoirs as source nodes,
pipe junctions, pipe elements, and demand nodes helped to analyze and
optimize the distribution network.</p><p>With district metering areas
properly demarcated and set in operation, various improvement measures
such as leakage control and throttling of valves for equitable water
supply have been implemented. With a population projected to grow to
300,000 by 2011, Badlapur now provides 24-by-7 water supply to 16 out of
34 wards, with the remaining wards to be completed this year.
Transformation of the intermittent system to 24-by-7 service
simultaneously reduced nonrevenue water loss by 427 million liters per
year, producing considerable cost savings.</p></span></div><div class="gmail_extra"><br><br><div class="gmail_quote">On Wed, Jul 17, 2013 at 1:33 PM, Yao Ayivor <span dir="ltr"><<a href="mailto:yamtanam@gmail.com" target="_blank">yamtanam@gmail.com</a>></span> wrote:<br>

<p>Dear Africa OSGeo members</p>
<p> </p>
<p>For my Master Thesis I'm working on a GIS based Decision Analysis on household water treatment for Uganda.</p>
<p> </p>
<p>Data I'm looking for includes:</p>
<p>- Water borne disease outbreaks </p>
<p>- Income Level</p>
<p>- good road layer (so far I'm working with Google map maker data)</p>
<p>- water availability</p>
<p> </p>
<p>The data should cover the whole of Uganda and the higher the spatial resolution the better (at least district level). Hope someone can help me in this matter.
</p>
<p> </p>
<p>Thank you in advance for your help.</p>
<p> </p>
<p>Regards,</p>
