APSC 101 Chapter 6: MODULE 6
Document Summary
Sustainability considered right from the start of the project. Small communities have more water boiling concerns, 80% of warnings are for communities of 500 or less. Concerns with water treatment equipment and processes. Difficult to supply chemical and parts to. Challenging to attract and retain skilled operators. Economies of scale; costs more to treat smaller volumes. Source water quality is often lower compared to larger ones. About adding positive contributions, not mitigating adverse effects. Life cycle thinking: natural resources extraction of raw materials, design and production, packaging, use and maintenance, disposal. Disposal hopefully have reuse, recycling, recovery of materials. Life cycle assessment (lca): a systematic evaluation of material and energy inputs and outputs of a product: considered in early stages of design. Systems thinking: how does the product interact with other products and elements that together form a system. Not only thinking about just the material but thinking about the whole picture.
