Infrastructures always had a both locally and globally key role in the economic and social development of countries. Investment in infrastructures, in particular by the private sector in most countries, has always been something to worry about for the governments of these countries and other performers in this area. In Iran as well, the problem of Financing for the improvement of infrastructures especially water infrastructures, including the purification and distribution of drinkable water is one of the problems that has challenged the managers of this field because of the strategic nature of this substance, they are constantly trying to attract more fund(capital) to improve and develop the water quality. Due to the insufficiency of raising capital and its lack of continuity through traditional methods of financing in this area (such as the issuance of bonds for projects by the government), crowdfunding is one of many Approaches that can not only attract more from micro-capitals, but also improve the return rate of capital or investment. In this research, by using the concept of crowdfunding and blockchain technology, we present a conceptual model to fund drinkable water production and distribution projects. in this model, by tokenizing the assets of a water production and distribution project, investors (corporative and micro) attempt to invest through a cryptocurrency trading system and based on the amount of their investment, they are shared in these assets and the profits from it. Also, in the section of water distribution to subscribers (household, industrial and agriculture), according to the amount of their savings or the specified inordinate consumption, they will be awarded with a prize/fine. a model like this can improve the management of water consumption by citizens while raising the capital of various investors in water production better.
