T2: Lessons learned from the Mediterranean countries using TWW for agricultural production

  1. 1. Lessons learned from the Mediterranean countries using TWW for agricultural production. Xanthoulis Dimitri Gembloux Agro-Bio Tech– Université de Liège
  2. 2. Constraints identification • Not enough treated wastewater of sufficient quality and quantity • Limited acceptance by the farmers and the end-consumer • No explicit national/governmental strategy on wastewater reuse • Storage: Continuous production but seasonal demand for treated ww; • Weak enforcement of existing legislation • Weak or non-existing organisation of the users of treated wastewater The main constraint is the poor water quality
  3. 3. direct negative impact The main constraint is the poor water quality (1) the introduction of modern irrigation techniques such as drip irrigation is difficult (2) frequent maintenance of equipment is required, which makes costly and cumbersome the irrigation activity.
  4. 4. success of irrigation projects with TWW Require: (1) the compliance of the TWW reuse standards for agriculture, (2) the irrigation perimeter shall be as close as possible to the wastewater treatment plan (3) the inter- seasonal storage should be possible (4) involvement of beneficiaries must be acquired.
  5. 5. Proposed actions As long term effect action, - Initiate a master plan for WWR - Rehabilitation of the public WWTP to meet the discharge standards in the natural environment As short term action; three pilot projects: a) monitoring of groundwater recharge, b) Implementation of a complementary treatment by sand filters before groundwater recharge to prevent clogging of infiltration basins and the need for periodic partial regeneration c) Improve tertiary treatment by sand infiltration followed by a maturation pond for direct reuse,
