At present, all the waste water from the toilets, sinks etc. from the hospital is collected at a central place near the vehicle entrance of the hospital and disposed of down a gulley. This water mixes with the waste water from the small village and during the monsoon the discharge of black water from the hospital mixes with the flow of water from the pavement near the entrance of the hospital, creating a small river down the hill. The water from the washing area of the hospital goes through a separate system and is disposed of at another place outside the hospital compound.
The compound housing and guesthouse each has a septic tank and in some cases a sink pit. The effluent from these systems is mainly disposed of over the cliff. The drawing on page 13 gives an insight into how the waste water from the hospital compound is disposed of. It is unknown how well or poorly the septic tanks function. If bleach is used, the septic tank has hardly any effect on the quality of the water.
The use of water by the hospital and compound buildings give an indication of the total waste water produced by the hospital. The discharges are:
Compound – 13 m3 water per day
Laundry – 7 m3 water per day
Hospital – 30 m3 water per day
Around the hospital Bhusaldada village has come into existence where people who have relatives in the hospital can stay and where also food for hospital patients is prepared. These houses don’t have running water in the houses. Water needed is collected in jars and carried inside. The municipality gave the following statistics about the houses/population in that village:
Total no. houses 115,
total number of population 659
septic tanks 10
open drains 3
Attached to the sewerage system of the hospital – all
Hotel number 46
