The ecological guard dog surveyed to evaluate compliance with the 2018 law, which needs a buffer zone of a minimum of 50 metres in between lakes and human activities to save the water bodies.
The lakes consist of Lake Kivu in Western Province, the twin lakes of Burera and Ruhondo in Northern Province, and Lake Muhazi in Eastern Province.
According to inspectors, contaminating these lakes might threaten biodiversity and the financial significance they hold for the regional population. Sardine (kind of fish) production in Lake Kivu varies in between 300 to 500 tonnes weekly.

Lake Kivu presently has continuous jobs to produce cooking gas and electrical power (produced by using its methane gas) to be incorporated into the nationwide grid.
Fishing, the twin lakes of Burera and Ruhondo supply water for hydropower production and are connected to the Rugezi wetland, one of the most essential birding locations in Rwanda.
Lake Muhazi, which provides income for the fishing neighborhood, streams into River Nyabugogo, which then assembles with River Nyabarongo, a tributary of the River Nile.

“The examination was performed in the lakes of Kivu, Muhazi, and Ruhondo. The exposed primary contaminating activities consist of lowering the surface area of Lake Kivu which takes place by disposing stones and sand in the lake, in addition to farming and animals activities, home and roadway building and construction activities, gardens and paths in the buffer zones where they are forbidden,” REMA’s report, which was shown The New Timessuggested.
The report kept in mind that “the evaluation discovered lots of activities contaminating Lake Muhazi on the side of Gasabo District and Lake Kivu on the side of Karongi District. These consist of discharging wastewater that is not very first dealt with into the lakes.”
Wastewater discharges include numerous hazardous compounds or chemicals, which might trigger negative ecological effects such as modifications in water environments, types structure, and a reduction in biodiversity.
Effluent discharges from markets and other financial activities can have a considerable influence on getting water bodies.

More than 30 percent of the markets do not treat their wastewater due to inadequate capability to treat their wastes, or treatment not being needed according to Rwanda Cleaner Production and Climate Innovation Centre (CPCIC).
High levels of suspended sediment and waste have actually caused significant financial losses due to the siltation of rivers, lakes, and tanks that create nearly half of Rwanda’s electrical energy.
Water resources board weighs in
“Findings from these assessments substantiate our water tracking results,” Remy Norbert Duhuze, Manager of the Water Monitoring and Quality Control Division at the Rwanda Water Resources Board (RWB), informed The New Times.
“Pollution of the majority of water bodies is primarily an outcome of unlawful human activities. Contaminated water will lead to an unfavorable effect on marine life such as the survival of fish and other water organisms, however likewise human activities that are water-dependent will not be sustained. Water treatment and supply facilities will require more efforts to deal with water,” he stated.
He stated the water resources board’s very first suggestion is to appreciate the law.
“Buffer zones on lakes and rivers must be strictly safeguarded versus advancement. Second, any release of pre-owned water into water bodies need to guarantee that the water is dealt with and abide by suitable quality requirements. The population must report any presumed misbehavior as these water bodies are public residential or commercial property that ought to be safeguarded by every person,” he kept in mind.
Preservation professionals have actually proposed a neighborhood participatory technique as a sustainable design that might end the increasing infringement of Rwanda’s significant lakes and rivers buffer zones.
Duhuze stated the community-based methods are likewise a great option.
“That’s why in the sessions we have with the official structures such as catchment committees and water users associations, in addition to conferences with neighborhoods, we constantly inquire to assist in implementing the laws and report any cases they observe.”
Charges waiting for polluters
“The fines are offered by the law and they are used,” Duhuze included.
The infraction is punished under the 2018 ecological law.
