The consultant, together with the PARC project team, Um El Nasser Municipality and the direct beneficiaries evaluated the established Communal Rainwater Harvesting and Infiltration Unit in Um Al Nasser village, the evaluation include:

1. Reviewing the design calculations (hydrological and others) and drawings of the unit in order to reassess its storage capacity, ability to handle potential severe rainwater storms as stated in the design calculation sheets (any lab tests cost should be covered by consultant). This may include assessment of the infiltration speed of rainwater at times of severe storms.
