The objectives of the Oum Er Rbia Sanitation Project for Morocco are to: (i) increase access to sewerage services and reduce wastewater-related pollution in selected towns in the project provinces; and (ii) pilot non-conventional technologies for wastewater systems in selected locations. This level one restructuring follows a request from the Office National de l'Electricite et de l'Eau Potable (ONEE) dated April 3, 2014, and its complement dated May 21, 2014. The changes under this level one restructuring are: (i) to simplify the project mainly by dropping the non-conventional technologies for wastewater systems component, and revise the original PDO, the project description and results framework accordingly; (ii) to reallocate the loan proceeds among categories of eligible expenditures; (iii) to revise the current financial covenant to be based on the more representative cumulative debt to equity ratio; and (iv) to trigger the Safeguards Policy OP/BP 4.11 related to physical cultural heritage since works implemented in the city of Bejaad might include a small portion of the Medina of Bejaad, which is classified and registered as national heritage, and add a legal covenant to that effect. There are no changes in the original institutional or fiduciary arrangements.
