### EXECUTIVE SUMMARY

The Drinking Water Supply Project in Urban Areas called 'PEMU' was implemented by the Democratic Republic of Congo as part of its post-conflict reconstruction and aims to substantially increase the production of drinking water, which is largely lower than potential demand and reduce losses of water billing in distribution networks and connections. The initial project which started in December 2009 covered the cities of Kinshasa, Matadi and Lubumbashi. In order to consolidate the achievements and specially to cover other cities of the DRC, the latter requested and obtained from the World Bank Additional Financing to the PEMU of 166 million US dollars. This Additional Financing includes, among other activities, the continuation of the reform of the water sector, the rehabilitation of old pipes, the extension of the network, the construction of pumping stations and treatment stations in the three cities of the project initial as well as in the city of Kindu. Concerning the city of Kinshasa, the new activities planned under the Additional Financing to the PEMU led to the lunch of construction works for the first module of the drinking water treatment plant in Kinshasa-Ozone with a capacity of 110,000 m3 / day, Including:

- - raw water catchment station on the Congo River with a capacity of 3 x 110,000 - raw water catchment station on the Congo River with a capacity of 3 x 110,000 m3 / day;
- - supply and installation of a DN 1,800 pipe for the delivery of raw water to the - supply and installation of a DN 1,800 pipe for the delivery of raw water to the treatment plant, a pipe with a transfer capacity of more than 3 x 110,000 m3 / day;
- - supply and installation of a DN1,500 pipe for the return of wastewater from the - supply and installation of a DN1,500 pipe for the return of wastewater from the treatment plant to the Congo River, a pipe with the capacity to discharge the wastewater produced by the treatment plant in its final capacity of 3 x 110,000 m3 / day;

The Government of the Democratic Republic of Congo intends to finance the second module of the Ozone factory (110,000 m3 / day) with a loan from OFID and the third module (110,000 m3 / day) will be built as part of the Kin Elenda project (ex PMDRUK). The implementation of this construction project for the third module of the Ozone plant will have negative environmental and social impacts which will, a priori, be very limited because many of these impacts have already been absorbed or mitigated on the occasion of the implementation of the ESMP for the construction project of the first module. It is therefore, in order to formally take into account, the preservation of the environment following the construction project of this third module of the Ozone factory that the promoter commissioned the realization of this Environmental Impact Assessment and Social (EIES). The strong growth of the Kinshasa agglomeration and the need to maintain and renew the existing water treatment installations forced the Government of the Democratic Republic of Congo to implement the Drinking Water Supply Project in Urban areas (PEMU) from November 2009 to December 2020. Despite the positive results achieved, the needs of the city of Kinshasa remain immense. In all likelihood around 2027, modules 1 and 2 of the Ozone plant will be operational. The drinking water production requirements for the entire city of Kinshasa, except for the municipalities of Nsele and Maluku, can be estimated at around 940,000 m3 / day (based on the report of the Master Plan drawn up by BCEOM in 2008).
