3) How much do the improved latrines cost, and who pays? EMW agreed to partially subsidize 126 HH latrines (pour/flush latrines with septic tanks) in the first phase of this program. An additional 74 HH latrines will be completed in the second phase. The EMW subsidy is 25 USD out of the base cost of 125 USD for the standard HH latrine (these costs are slightly higher than the original proposed cost because of the steadily inflating cost of materials and skilled labor (see below). Given the significant unmet demand on the part of potential customers, EMW anticipates a substantial expansion of this program, as suitable funding sources are identified. Unmet demand for improved sanitation in Quang Nam (and some of the surrounding provinces) remains high, and EMW intends to help meet and further stimulate that demand.
4) What are the basic design features? The basic sanitary latrine is a one-hole, pour flush double vault (septic tank) latrine, with a shelter (typically brick ventilated walls, and a corrugated iron roof) for privacy. However, an increasing number of HHs prefer to upgrade their basic latrines to a bathroom that contains the latrine and bathing facilities, along with improved aesthetics (tiled walls are popular for those who can afford them). The EMW design is based on designs that were promoted by International Development Enterprises (IDE) during their recent multi-year market-based hygienic latrine promotion project in Quang Nam. EMW’s latrines have been constructed mainly in Quang Nam Province, which is also the main focus of the EMW Clean Water Program thus far. The EMW program takes advantage of the availability of trained latrine builders whom IDE had trained-up during their program, as well as IDE’s promotional and marketing activities that helped to identify and expand the market demand for hygienic latrines.
5) How about alternative latrine designs? – EMW also intends to initiate a pilot program for the promotion of Eco San latrines. Ecological sanitation (also called 'EcoSan') is structured on recycling principles that keep the eco-cycle in the sanitation process closed. This system uses human excreta as a resource: human waste is processed on site until they are free of pathogenic (disease-causing) organisms. After this process, the sanitized excreta can be used for agricultural purposes. EcoSan toilets have several advantages over standard pour-flush latrines, including an EcoSan toilet can solve problems like bad odors, flies and poor hygiene, and is a comfortable and safe alternative to pour flush latrines. However, as this is not a common design in Vietnam, EMW will promote the EcoSan toilet as a useful alternative to the standard pour-flush latrine. The extent to which they are financed under this project will depend upon the willing of families to adopt the new technology.
6) What is the typical cost of a HH latrine, and how does the co-financing arrangement work? The typical cost of a basic pour-flush latrine with a septic tank is about US$130 (about VND 2.1 million), reflecting the recent significant increase in the price of goods, materials and skilled labor in Vietnam, due at least in part to the booming local economy. EMW provides a subsidy of 20% of the cost of a basic pour/flush latrine as a financial stimulant to encourage families (especially low-income families) to build improved sanitary latrines. The EMW subsidy is 20% of the total cost, or about VND 420,000, or about $26/HH. Sometimes people choose to build upscale versions that cost up to $300-500 for a tiled bathroom, a pour-flush latrine(s) and a shower, financed by the users.
