With the help of Church of God in Christ Manonnite, six Community Drinking Wells were dug earlier in six villages in the Chingleput area.

During 1986, one bore well including laying of pipe line was sunk at Mannameri village near Arkonam. This bore well was connected to the Panchayat water supply system with the approval of the village Panchayat. This water supply system was dedicated by Rev. John Duke of the Church of God in Christ Mannoite on the 11th February, 1987. The bore-well sunk by TNCC was the only source then from which the entire village population of over 2000 people got adequate drinking water.

The Church of God Christ (Mannonite) also came forward to provide support for one bore well for the Scavengers Colony near Kancheepuram since they had been suffering a great deal for want of drinking water in their colony.

With the support of CORAR, deepening of one community drinking water well was taken up at the premises of KERIETH in Yelasandra village, Bangarapet.
