Ecosystem Services

Provisioning

  • Provisioning Services are ecosystem services that describe the material or energy outputs from ecosystems. They include food, water and other resources.

Regulating

  • Regulating Services are the services that ecosystems provide by acting as regulators eg. regulating the quality of air and soil or by providing flood and disease control.

Habitat / Supporting

  • Ecosystem services "that are necessary for the production of all other ecosystem services". These include services such as nutrient recycling, primary production and soil formation.

Cultural

  • Cultural Services corresponds nonmaterial benefits people obtain from ecosystems through spiritual enrichment, cognitive development, reflection, recreation, and aesthetic experiences.

EH Engineering Solutions

Different species of biodegradable plants and algae

Different species of biodegradable plants and algae has been functioning in the wetland to the treatment of 4000 liters sewage/wastewater collects per day from the buildings of PCRWR.

Wetlands 748 sq ft, 0.50 acre office

Wetlands 748 sq ft, 0.50 acre office construction and 1.25 acre catchment area are the Ecohydrological infrastructure of PCRWR. However, the different varieties of Hydrophytes, submerged plants, algae and fruit plants were produced by bio-technique to increase the wetland wastewater treatment efficiency and the increase production of fruits per acre.

Project Activities

  • The sewage treatment and production of bio-engineered plants, restoration of wildlife (birds) species and development of recreational site for the employees are the key activities of the titled wetland.

Expected Outcomes

Wastewater/sewage disposal has stopped into the fresh water bodies. | Conserve freshwater that had used for plantation and nursery on daily basis. | Healthy growth of plants and fruits production. | Wildlife restoration.

Project Objectives
  • Culture, Sociologically the recreation site creation and biomass has improved health of employees & citizens. Education, Through capacity building the wetland development technical knowledge has started to share with water sector Stakeholders, Academia and Private Sector as well. Law, PCRWR with the treatment of wastewater has started to implement/follow the fresh water protection Acts/Laws of the Local Government/Environmental Protection Agency/City Development Authorities/Municipal Agencies with true letter and spirit. Policy, Under the framework of Pakistan National water policy 2018, Climate change policy 2021 and National Sanitation Policy 2006, the wastewater treatment model of wetland has developed by PCRWR for addressing the climate change and water resources challenges in country like Pakistan. Governance, PCRWR is an organization of the Federal Government of Pakistan working under Ministry of Water Resources and has a mandate to conduct research on all aspects of water resources and main focusing on the achievement of national water policy targets and Pakistan International Commitments/Sustainable development goals 2023. Recently, PCRWR has drafted National Water Conservation Strategy compliance to same, PCRWR has constructed a wetland and started the treatment of wastewater generated on daily basis in office premises. PCRWR has started to sensitize and replication of this model with other public & private sector departments for reducing and reusing the wastewater and also, conservation of fresh water resources across the country.
