The Impact

This paper explores the impact of water conservation and rainwater harvesting practices implemented at the site or district scale on the infrastructure, energy and water cycles of their larger urban systems. A case study is presented of a conceptual development in a Southeast Asian climate. Two technologies are examined: water-efficient fixtures and appliances and rainwater harvesting and beneficial use. Practices to reduce water consumption at the site or district scale have implications in the larger system, ranging from reductions in water that has to be treated and distributed, reductions in wastewater that has to be collected and treated, and reductions in energy consumed. Similarly, using rainwater for irrigation will reduce the amount of potable water demand, and will have system energy implications. The paper considers performance criteria for the entire water-energy system, including peak runoff, pollutant loads, energy and carbon footprints.

And Performance

Rainwater harvesting is a simple and effective tool to collect and store water for domestic and institutional use. In developing countries, captured rainwater can be used to replace or supplement government-supplied or manually-transported water. A rainwater harvesting system consists of a catchment area, gutter, and storage tank. Gutters typically have a V-shaped, trapezoidal or rectangular cross-section. This work presents a case study on the design and performance analysis of three conventional and one novel, “wrapped” gutter cross-section along with the implementation of a novel gutter design in the developing world. A Team of undergraduate students performed the design and analysis and, though a service-learning experience in May 2013, investigated barriers to implementing rainwater harvesting in central Kenya. It was found that while gutters can be easily fabrication and installed using locally-available materials and skill-sets, for consumer, the potential return on investment was low and the cost of implementation was high. For producers and installers, non-uniform roof designs and conditions was a major obstacle.
