In that context, the forthcoming initiative by the Korean government to accelerate the renewal of water supply and sanitation infrastructure can contribute to the further deployment of K-SWM at local level. Efforts to minimise non-revenue water will resonate with users’ priorities and concerns when water tariffs better reflect the full cost of supplying water, including the cost of investing in and operating and maintaining the w'ater supply infrastructure, the environmental and opportunity costs of abstracting water and preventing other uses (for industry, the environment, or else). Similarly, a municipality or utility will only be able to finance K-SWM w'hen water savings compensate investment and operating costs, that is, when revenues from water tariffs tend to reflect full water supply costs. This explains why the diffusion of SWM in Korea is directly related to issues discussed in Chapter 3, and to other issues related to tariffs for water supply and sanitation services (an issue not covered in this report).
