Eliminate free-riders to help achieve Sustainable Development Goal 6

To achieve SDG 6, water and sanitation utilities must be financially sound. To increase their financial resources, utilities must both increase efficiency — do more with less — and find ways to increase their total cash inflows. In many countries operations and maintenance of combined systems are often funded solely by tariffs charged to sewerage customers, meaning that stormwater beneficiaries get a free ride — that they do not pay for the stormwater services they receive or the flooding that the impervious surfaces that they own help cause. Charging stormwater combined system beneficiaries create an additional cash-stream that would help cities to sustainably manage their combined systems — helping them to achieve their SDG 6 commitment.
