namibia rural water supply development plan
The government of namibia completed a regional Water Supply Development
plan to identify infrastructure needed to meet the goal of supplying 90 percent
of the country with improved water. Forty percent of the population lives in
four northern regions covering 85,000 square kilometers, with a combined
human and livestock demand of 48,295 cubic meters per day. lund consulting
engineers assessed the existing coverage and capacity.
WaterGemS models were created based on field data transferred from the
GIS database and simulated 6, 230 kilometers of pipeline. System performance
profiles with variables such as delivery pressures and velocities defined regional
patterns. The modeling results demonstrated shortfalls in the current system
and justified the proposed addition of 1,000 kilometers of pipeline, 500 water
points, and 17 booster stations.

operational diagnosis and contingency plan
Porto Alegre, Brazil
The water supply systems in the metropolitan region of porto Alegre, Brazil,
serve 1. 2 million people in seven counties. With 321,000 water connections,
average consumption is 4. 4 million cubic meters per month. magna engenharia
developed an operational diagnosis and contingency plan for mitigating the risk
of pipe breaks, service interruptions, and other situations.
magna used WaterGemS to develop a hydraulic model of the water
supply system based on legacy cadastre maps, field surveys, and tests
and measurements. The model revealed several causes of water loss and
performance degradation, including standing water in reservoirs, closed valves,
and overworked pumps. corrective measures could reduce water loss by up to
20 percent and changing pump operating procedures could save $300,000 per
year in electricity costs.
