The purpose concerning this paper is to review the belongings of inadequately operating decentralized waste treatment orders, lack of sewerage schemes/networks and their centralized sewage situation systems, and wrong disposal of dimensional and liquid waste (sewage mixed with added hazardous treated chemicals from poisonous tanks or toilets) on the aquatic atmosphere (surface water and groundwater) and human life. As a result of the lack of a sewerage structure or network in the country, 81.6% of the improved cleanliness in Rwanda uses pit latrines with continuous slabs, according to the census report of household living environments EICV 4 that was approved for one Rwanda National Institute of Statistics in March 2016. High-altitude terrain has significantly contaminated surface and groundwater in any of locations, containing the capital city of Kigali. The complexity of wastewater administration has also been infuriate by the extreme level of life in the district and the absence of government payment for the creation of miscellaneous initiatives for concentrated sanitation. A count of 1.3 million crowd in Kigali means that the city has neither concentrated sewage situation nor central waste networks. Except for a few semi-concentrated sewage situation systems, poisonous tanks with soak-continuously pits are primarily secondhand, together with pit latrines. Due to not cooked sewage being disposed incorrectly into the environment, they have potential negative impacts on surface and groundwater possessions or in some cases direct discharge to open waterway. Current examples of streams and rivers taking inappropriately given sewage contain Ruganwa, Rwanzekuma, Yanze, and the Mpazi rivers, as well as all tributary of Nyabugogo River. The problem of water contamination is getting poor as anthropogenic contaminants enter the water era. Emerging organic contaminators (EOCs) are of particular concern. For example, pharmaceutical and private care products are not controlled under current environmental regulations. Therefore, they may cause environmental or human health impacts. Since 2016 Kigali city was projected to have the first centralized sewerage scheme and construction of wastewater situation plant through the project named “Rwanda Sustainable Water Supply and Sanitation Program (RSWSSP)”. The definitive version of the environmental impact estimate (ESIA) received by Rwanda Development Board established that this problem will be focused on by the RSWSSP program by developing Kigali's first concentrated sewerage whole, as well as by directing the solid wastes and fecal sludges create by the 6 subsidiary cities of Kigali. However, even though the project’s ESIA has already existed finished it has not been executed yet. The paper checked the main causes of water pollution in Rwanda's stupidly populated areas, specifically in the capital city Kigali, the potential effects of a lack of city centralized seepage systems, the inadequacy of now available scattered technologies to keep human life and the ecosystem, and all's awareness of the new natural water contaminants that are now being found in water environments. Also submitted were some of the best and brightest management methods for safeguarding Rwanda's water resources.
