These days, public services such as water, electricity, gas, etc … have become an indispensable and integral part of human life, so even living without the benefit of these services seems impossible. With the widespread need of society on the one hand and the number of crimes in this area on the other hand, the need for preventive actions and strict confrontations is increasingly felt. The Iranian legislator has also enacted numerous laws that have either been dealt with a one-by-one case basis, such as the Fair Water Distribution Act, or in a few cases as provided in articles 660 and 687 of the Islamic Penal Code Section on related crimes which have dealt with several public services such as water and electricity. The last will of the legislator in the field of public services is the law on unauthorized users of water, electricity, telephone, sewage and gas, adopted on 1396/03/10, which despite having deficiencies and uncertainties plays an important role in updating laws and removing some flaws and ambiguities of the previous rules. In this article, we tend to review this newly adopted law by emphasizing on the laws relating to water and sewage.
