Water pollution is caused when substances accumulate in water sources to an extent in which they become harmful to human beings and animals. A law on the Prevention of pollution was enacted in 1970(Japan) response to the rising rates of water pollution.


The law was enacted to: Prevent pollution on waters such as lakes so as to conserve the environment by controlling effluents discharged from factories and protecting the victims of the hazards brought by such discharges by being compensated by the firm responsible and also a punishment to the firms responsible.

Areas to be controlled

Public water areas such as lakes, rivers, and ponds used for public purposes.


Effluent standards are set in terms of permissible concentrations of each toxic substance in order to protect the environment and human health. Effluent standards are of two types; common national standards and the more strict effluent standards. These standards are set by the Prime Minister’s office order. Features of the Law on the Prevention of water pollution

When I worked on my dissertation I got a law dissertation help which is of the essence to factories and eve household as it enlightens them on ways to prevent and control water pollution by giving them alternatives and also the resources to be able to control water pollution.

The law has been divided into chapters as will be shown below

Chapter 1: The law was enacted for the purpose of preventing and controlling water pollution, protecting and improving the environment and safeguarding human health. This, however, is not applicable to the prevention and control of marine pollution. The relevant departments under the government must also incorporate the protection of the water environment into their plans and adopt ways to prevent such pollution.

Chapter 2: Regulation of discharge of effluent by checking the number of toxic substances in the effluents and also the manner in which it is discharged. This chapter also explains the promotion of measures of domestic wastewater by imparting knowledge on the citizens and also a provision of necessary facilities to reduce the pollution in these areas.

Chapter 3: Monitoring of the conditions of water pollution. This will be done by government bodies such as the chiefs. The conditions of water pollution shall be continuously monitored and the results shall be reported to the Office of the Minister of Environment.

Chapter 4: Compensation for damages. This indicates that in cases where human life or health is damaged as a result of the harmful substances in the discharge of a certain factory, the involved enterprise is liable for compensating those affected from the damage. This will however not apply for cases in which the affected was in charge of the work.

Chapter 5: Penal provisions. Any person who violates the orders issued under the act shall be liable to penal servitude or a fine in accordance with the weight of the crime committed.
