Job Potential: 231 Preparing the solid waste materials in usable form—perforating plastic bottles, processing biomass residues, and generally constructing the DEWATS— proved to be painstaking tasks for the project team. “But for small communities, where processing areas for waste materials can be established, the DEWATS can be easily replicated and could become a source of community livelihood,” the project team recommends. Social Considerations 232 1. Establishing of multi-stakeholder networks to combat water pollution 2. Building up implementation capacity on various levels 3. Providing treatment for both, domestic and industrial wastewater at affordable price 4. Fulfillment of discharge standards and environmental laws 5. <strong>Waste</strong>water pollution reduced by up to 90% 6. Providing treatment for wastewater flows up to 1000 m3 / day Economic Instruments for Overcoming Barriers 233 The project, under the ASEAN University Network-South East Asia Engineering Education Network (AUN/SEED NET), is funded by the Japan International Cooperation Agency (JICA). Advantages to Developing Countries 234 The state-of-the-art technology at reasonable costs, resulting from the use of local materials, has made DEWATS applications popular in the developing world. The system costs less than conventional septic tanks, and can last for many years. It can be used for both centralized and decentralized systems, as it can easily be reinstalled in other sites. More importantly, it solves both the wastewater management problem and the problem of solid waste disposal. Disadvantages to Developing Countries 235 One drawback of the DEWATS is that it is not large enough. The pilot-scale system could only treat one cubic meter of wastewater at a time. The septic tank would also require de-sludging every two or three years. While the technology is sound, low-cost, and durable, however, there is another downside to the DEWATS. Example of Real Life Applications 236 The project aims to solve sanitation problems and environmental pollution caused by improper sewage disposal using a low-cost decentralized wastewater treatment system (DEWATS). DEWATS treatment efficiency for a hospital wastewater is found below. 231 Ibid. 232 http://www.borda.de/conrat/Dewats_Mai05_72.pdf 233 http://www.adb.org/water/actions/PHI/using-solid-waste.asp 234 Ibid. 235 Ibid. 236 http://www.up.edu.ph/upnewsletter.php?issue=28&i=414 412
