Co-operation has always been a characteristic of traditional societies like that of Kohlu. Although people do co-operate in agricultural tasks and other communal activities, any formal type of co-operation is non-existent in Kohlu. At the time of a marriage friends and relatives of the groom’s family contribute some money for the marriage expenses which is called mana mokh. The relatives and friends also contribute in case the fellow tribesman has been fined or in case he has to pay some compensation money.

A newly introduced form of induced co-operation is management of water supply schemes by the community. The schemes are completed by the Public Health Engineering Department and afterwards they are handed over to community committees, called Water Management Associations. These associations fix a tariff for the water consumers, operate and manage the schemes, and arrange for minor repairs up to 10 thousand rupees, if needed.
