Results of Wastewater Treatment Plant Audits April 2013 - October 2015 April 2013 – March 2014 April 2014 – October 2015 # of plants audited = 82 • # of plants audited = 47* Managing and protecting Jamaica's land, wood and water
Results of Wastewater Treatment Plant Audits April 2013 - October 2015 (cont’d) April 2013 to March 2014 April 2014 – October 2015 Parameters with highest incidence of non-compliance Total Nitrogen, Biochemical Oxygen Demand, Chemical Oxygen Demand, Faecal Coliform, Total Suspended Solids • Parameters with highest incidence of non-compliance • Total Nitrogen, Total Suspended Solids, Chemical Oxygen Demand Managing and protecting Jamaica's land, wood and water
Results of Wastewater Treatment Plant Audits April 2013 - October 2015 (cont’d) • Issues observed • Lack of flow measurement devices • Lack of standby power • Some components of plant not operated in accordance with best practice (to potentially save on energy costs) • Disinfection not practiced or not properly carried out Managing and protecting Jamaica's land, wood and water
Re-use of Wastewater • Existing licensed facilities re-use treated effluent for irrigation • Benefit from discount on discharge fees • Majority of facilities that re-use effluent are in the hotel sector Managing and protecting Jamaica's land, wood and water
Re-use of Wastewater (cont’d) • ISSUES: • How can we increase re-use? • Do we have the data to support the push for re-use in light of CECs? • Cannot re-use effluent that does not meet the standards • Buy in from general public Managing and protecting Jamaica's land, wood and water
Chemicals in Wastewater: Contaminants of Emerging Concern (CECs) • Chemicals that are being discovered in water that previously had not been detected or are being detected at levels that may be significantly different than expected. • Pose a risk to human health and the environment as a result of their presence, frequency of occurrence, or because their source may be unknown. Managing and protecting Jamaica's land, wood and water
Chemicals in Wastewater: Contaminants of Emerging Concern (CECs) (cont’d) Q: How do CECs get into wastewater? A: From the use of pharmaceuticals and personal care products (PCPs) Managing and protecting Jamaica's land, wood and water
Chemicals in Wastewater: Contaminants of Emerging Concern (CECs) (cont’d) • Examples of CECs • Polybrominateddiphenyl ethers (PBDEs) • Perfluorinatedcompounds (PFCs) • Widely distributed and persistent in the environment. • Both accumulate in human tissue or blood, and are associated with health effects including endocrine disruption. Managing and protecting Jamaica's land, wood and water
Chemicals in Wastewater: Contaminants of Emerging Concern (CECs) (cont’d) • WWSR promotes re-use (S. 45) • Re-use necessary to meet current and future demands • ISSUES: • What are the CECs in our wastewater? • What impact will these have on our environment and health with increased re-use? Managing and protecting Jamaica's land, wood and water
Economic Valuation in Wastewater Management • ISSUES • Currently not being done in Jamaica • In general, economic valuation usually not done because of inadequate property rights, presence of externalities and lack of perfect information (Hernandez-Sancho, et al , 2010) • What is needed to start carrying out economic valuation in Wastewater Management Reference: Hernandez-Sancho, F., Molinos-Senante, M. and Sala-Garrido (2010) Economic valuation of environmental benefits from wastewater treatment processes: An empirical approach for Spain. Science of the Total Environment, 402 (4) pp. 953-957 Managing and protecting Jamaica's land, wood and water
Financing Wastewater Management • ISSUES: • Funding for maintenance of plants - critical • Funding for capacity building (both regulated and regulator) • Inadequate resources available to give effective oversight (from the regulator standpoint) • Obligation of government to ensure a healthy environment for citizens. • Use of effluent discharge fees to augment. Timeline for when this will become feasible. Managing and protecting Jamaica's land, wood and water
