The unit is functioning smoothly for the last 34 months. As it was due for desludging, Sri. V. C. Sudhakar, President, and Sri Balasubramanian, Executive Officer of MSGTP, were informed of the necessity. Though they were initially reluctant to bear the cost, the advantages (savings from frequent desludging of septic tanks in the past) and exposure gained by MSGTP through this DEWATS unit was explained to them.  On mutual consent, cost estimation was worked out. To mark the uniqueness of the activity, it was decided to take it up on the 19th November 2009 - World Toilet Day.

A series of discussions and planning discussions with the officials of the Town Panchayat were held to organise the required equipment, manpower and other logistics.

MSGTP deputed 8 skilled sanitary workers to understand, execute and get trained through this ‘Hands-on Training exercise’. The Programme staff of ExNoRa International elaborated on the activities to be carried out in each module. The Sanitary workers were divided into three groups and given charge of one DEWATS module each.

In planted gravel filter, the overgrown plants were trimmed to a height of 1 foot and then uprooted for replanting. The filter material was back washed and floating impurities removed. The inlet and collection pipe ports were thoroughly cleaned.  The operation ended after planting 32 canna indica and 32 reeds in the prescribed manner.
