On the ground<\/h2>\n\n\n\n

The discharge of hospital wastewater that needs treatment is very high, and its open runoff into communities is a significant risk to people’s health.<\/p>\n\n\n\n

The District Government Hospital & Medical College is a 1,300 bed facility and provides free healthcare to communities mostly to low income groups. The hospital has 2 blocks for Comprehensive Emergency Obstetric and New Born Care (CEMONC) with inpatients, and 2 women\u2019s hostels for women students and in house staff.<\/p>\n\n\n\n

All waste water from these buildings are not collected or treated in sanitation systems and instead let our into the open behind the hospital campus. The constant flow of waste untreated water is a high risk factor for groundwater contamination and health hazard to the community around.<\/p>\n\n\n\n

In detail<\/h2>\n\n\n\n

DEWATS is a biological wastewater treatment system which functions through natural and biological degradation of organics by anaerobic microorganisms. DEWATS technology is based on the principles of \u201cnature based\u201d, \u201clow operation and maintenance cost\u201d, \u201cconstructed using locally available\u201d and functions \u201cwithout or less external energy inputs or mechanical devices\u201d. DEWATS modules are based on sedimentation, anaerobic digestion in suspension and in fixed beds, aerobic digestions and polishing treatments.<\/p>\n\n\n\n

This Project will undertake the installation of a waste water treatment system through the DEWATS approach for one CEMONC building. This would include setting up of a facility involving either prefabricated or concrete waste treatment chambers to treat the water.<\/p>\n\n\n\n

Preliminary needs identification visits have been held with the Hospital\u2019s Dean, Administrative Head, Senior Heads of Departments, and the Public Works Department of the District\u2019s Municipal Corporation. The process of DEWATS and its benefits have been briefed in detail to the Hospital. The Hospital has given full support for the project in writing. The Public Works Department has issued a no-objection for undertaking this project.<\/p>\n\n\n\n

The project will include necessary assessments and water quality checks before and after implementation. The completed project will be inaugurated and handed over to the Government authorities for necessary operation and maintenance. Required training to the Government staff for sustainability will be given through the project.<\/p>\n\n\n\n

The project also plans to engage with the students of the hospital, the Student\u2019s Green Club and the Group D grade of maintenance staff and train them on the DEWATStechnology. Adequate training and handholding for operation & maintenance will be provided through the project.<\/p>\n\n\n\n

Perspectives of sustainability<\/strong><\/h3>\n\n\n\n

The DEWATs functions with nature based waste water treatment methods. The operation cost to the facility is very negligible compared to conventional sewage treatment plants as there is no machinery involved. Maintenance would mostly include removal of accumulated sludge once or twice a year and routine checking the tanks for potential clogging due to sanitation products like napkins etc wrongly disposed by the hospital\u2019s inmates.<\/p>\n\n\n\n

This maintenance can be easily done by one assigned existing staff of the hospital. A maintenance schedule can be maintained by the hospital\u2019s administration department for routine cleaning of the sludge from the chambers and tanks.<\/p>\n\n\n\n

The hospital senior staff and maintenance staff will be adequately trained with technical expertise at the time of commissioning the project.<\/p>\n\n\n\n
