Workshop on establishment of effluent guidelines and standards in CARICOM/CEHI member states

As part of activities included in a CEHI/CARICOM/UNDP Regional Sewage Disposal Studies Project, two workshops on the Establishment of Effluent Guidelines and Standards in CARICOM/CEHI Member States were convened in Trinidad and Jamaica from December 3-5 and 7-9, 1992. These two workshops were a follow up to a two-day workshop on the Technological and Policy Implications of Effluent and Ambient Guidelines in the Caribbean, held in CEHI in St. Lucia from 5-6 June 1991. These workshops were convened to address four immediate objectives of the Project in a broad sense: 1) to develop technology based effluent standards and guidelines for sewage effluent disposed of in Caribbean waters; 2) to formulate technological options for sewage and sewage sludge collection, treatment and disposal; 3) to assist in the rehabilitation and improvement in the operation of treatment facilities; 4) to develop water quality standards for beaches

Status report on the sewerage sector in Grenada

Gives general background information on economic, health and environmental conditions in Grenada. In so far, as the sewerage sector is concerned, data indicates that approximately fifty (50) percent of households use pit latrines, six (6) percent are linked to the only sewerage system in St. George's and forty (40) per cent use septic tanks. Details of the operation, maintenance, technology and financing of the sector are outlined. Identifies a number of projects that should be given serious consideration for implementation , including a sewerage system for the Grand Anse area

Allows for the selection of an economically sound sewerage scheme which will make Rodney Bay a pollution free are for the polution induced by waste water

Developing alternative approaches to urban wastewater disposal in Latin America and the Caribbean

The explosive rate of urbanization and industrialization in Latin America and the Caribbean has aggravated serious wastewater disposal problems. To address those problems, sound pollution control programs are needed - programs that are founded on a firm legal base and supported by an institutional infrastructure suitable for their effective operation. Such programs should make a point of employing technologies that are appropriate for the climatic and economic conditions prevailing in the areas they serve. Promising methods for dealing with such problems include use of submarine outfalls with minimal pretreatment for cities along coasts and estuaries, maximum use of receiving waters' assimilative capacity (as determined through application of system management and water quality models), reuse of treated sewage effluent for irrigation, and the application of unconventional technology for urban slum sanitation. This article reviews those various approches and describes the ongoing collaboration between national governments and PAHO's Pan American Center for Sanitary Engineering and Environmental Sciences (CEPIS) in the areas of research, information exchange, human resources development, and institutional development for the purpose of establishing a viable strategy and framework through which these major problems can be confronted and perhaps ultimately over come.(AU)

Union sewage disposal biogas and waste recycling project

Three systems exist in sewage disposal with no provision for the utilization of the sewage as a potential energy service or as fertilizer. Production outputs consisting of 8,815 one hundred bags yearly. Outlines the projects four major areas-: collection system; digestive and gas holder; sludge treatment system (Au)

Effect of seasonal effluent chlorination on coliforms in Jamaica Bay

Quite frequently, the need for chlorinating effluents discharged to receiving waters not used for recreational purposes is questioned. A study was undertaken to demonstrate that chlorination of wastewater treatment plant effluents that, by volume, represented less than 0.5 percent of the receiving water volume, would significantly improve the bacteriological quality of Jamaica Bay. This estuary was an ideal site for such an investigation because more than 99 percent of the treated effluents being discharged to the Bay are chlorinated on a seasonal basis only- May 15 to September 30.
