Sanitation — Soak Away Pit During the daily operation of medical activities, mass immunization campaigns and even in emergency situations, good health care waste management (HCWM) is crucial to prevent the exposure of health-care workers, patients, waste handlers and the community to infections, toxic effects and injuries. Poor management of health-care waste may also damage the environment. (WHO, 2007). In developing countries, HCWM is still poor. Approximate % of waste type per total Often, accurate materials, knowledge, and skills of how proper HCWM can be implemented is waste in primary health care centers: lacking. In addition to the waste types mentioned Non-infectious waste: in the chart to the right, wastewater, especially Pathological waste and infectious waste: laboratory wastewater, is also important to con- Chemical or pharmaceutical waste: sider. Most of the chemicals used for cleaning Sharps waste: materials, sterilizing, disinfecting products and Pressurized cylinders, broken therpermuted substances, etc. are mixed with the mometers, etc… wastewater from the laboratory and ultimately discharged in public drainages, land fields, etc (WHO, 2007).

In Rwanda, laboratory wastewater at the Health Center level has to be drained to a soak away pit for filtration before it is discharged underground. This is to minimize health risks that may be associated with poor handling of laboratory wastewater (Ministry of Health, 2007). Bisate Health Center has the advantage of being located in area where there is a high percolation and a deep aquifer (estimated to be at 750 m deep). These geological characteristics favor evacuation and filtration. The installment of the soak away pit helps to ensure proper health facility hygiene and safety of the health care staff and the local community.

Cost of Soak-Away Pit Soak Away Pit Design - General Quick Steps: 1. Dig the soak pit 500 Fired Bricks 15,000 2. If the soak pit area is very sandy, the hole may need to be lined with bricks 5 Rebar 12mm 30,000 for additional wall support. 2 Steel Wire 2,400 3. Lay a 4 cm layer of sand on the bottom of the pit. 1 Truck Sand 50,000 4. Lay a 4 cm layer of gravel over the sand layer. 4 PVC Pipes 110mm 40,000 5. Fill the hole with rocks up to the height of the end of the pipe from the 4 PVC Coude 110mm 10,000 wash area. 1 Te PVC 2,500 6. Under the end of the pipe (which should reach the radius/center of the top 47,500 view), place a good, flat rock in order to encourage the spread of the out- 5 Sacs Cement Labor 39,000 flow of the pipe throughout the rocks in the soak pit. 236,400 7. Leave an empty space around the flat rock and end of pipe, creating a “hole” surrounded by rocks. 236,400 RWF @545 = $433.00 8. Continue to completely fill the rest of the soak pit with rocks. Place rocks over the pipe, but not touching, to protect it from upper pressure and cover your middle “hole” with a top rock as well. 9. Cover soak pit with sticks, rice sack or plastic, and mud. Make sure mud area is compacted and strong. Note: This is the “village,” cheap way. 10. If soak pit area is in a high traffic zone (i.e. cars, donkey carts, heavy items), you may need to cast a concrete slab with rebar to cover it, instead of sticks and mud.
