Case study


The participants had to solve a case study at the end of the workshop:

A Nepali community, 20 km from  Kathmandu
1000 houses
5000 people
80 % farmers:
  • arable land
  • 40 farms with totally 200 cows
  • a dairy
Top View Hotel, close to the dairy, 30 beds, flush toilets
Stormwater system - well designed, but needs maintenance
"Shitting fields" of "first category"
Sewer system only for hotel and dairy, discharges on the river
Drinking water
  • enough wells
  • quality below standards

Case

Try to give solutions:
  • short term: what can you do your self
  • long term: what needs careful planning and project support

The participants had 45 min to give an overview of the solutions:


1. Participants from Kusunti

Short term solutions

Minimise water use in toilet. Do not mix black and grey water. Waste from the toilet should be collected in a septic tank. Liquid portion should be drained out of the septic tank and sludge should be used as manure after mixing with cattle dung and other agricultural wastes.

Local people should be educated and motivated to discontinue the use of open toilets and make public toilets and wastes from the toilets should be used as manure. Rainwater should be collected in a big pond and due to evaporation and infiltration water in wells and springs will be increased.

In order to improve personal hygiene and awareness various activities should be launched. While doing aforesaid activities public should be involved in order to solve technical and financial problems.

Long term solutions


2. Participants from Thimi

Short term Solutions

- polluter pays

- waste is our valuable manure

- money does not stink

Long term solutions


3. Participants from Panga

This is a very beautiful place. Shitting fields are the main problems of this community. Open toilet has badly affected this community because there is a Top View Hotel where tourists stay. Community should be kept neat and clean in order to impress tourists. Since most of the people are farmers they badly need manure. Another problem of this place is the need of repair of drainage of rainwater.

First thing that we need to do to solve the problem of this community is to bring awareness in local people. People should be educated about grey water and black water and that this should be kept separate. People should be educated about the importance of appropriate toilets and the black water which can be used as manure and fertiliser so that black water and grey water do not mix with each other. Grey water can be treated by making two ponds and planting reed. In this village stormwater drainage should be properly maintained. People can also collect donation and maintain. For solving the problem of dairy factory effluent local people should be united and raise tax from the factory. As a result, wastewater generation will be less.

Polluter pays system can be implemented. Since there are sources of water and several wells ponds should be cleaned and water should be collected so that water does not dry in the wells.

Regarding large scale solutions: due to the lack of private toilets, public toilets should be constructed in different places. A manure enterprise can be developed here. Since this community has a population of 5000 and 80% of them are farmers the people will benefit from the manure industry. Raw materials needed for the industry can be obtained from wastes generated in the community. This helps in keeping the village clean and people will be affected too. For tourism also this place should be cleaned.

* Our guess is that the community is Dakshinkali (wrong, but could be a good example. It was just an imaginary village, well applicable to the four villages, Ruud Kampf).).


4. Participants from Sidhipur

The village is 20 km far to the East. It has got a population of 5000 and 1000 households. 80% of the people are farmers. There is a Top View Hotel with 30 beds and flush toilets. There is a lot of arable land and people have 200 cows and there is also a dairy factory. People do not have latrines.

The problems of the village can be solved in two ways.

Short term solutions

Long term solutions


Final remarks

Some remarks from the organisers. We were very impressed by the oral presentations. It was not possible to distinguish easily between the quality of the solutions. We decided to give the first price in the case study to the participants of Thimi however, leaving second prices to the other participants.
