Rain water harvesting pits was dug in 125 parishes during the monsoon season in 2004. The slogan is ‘Not to waste rain water falling in our Church land’. The diocese is encouraging members to construct fibrocement tanks to harvest rain water in all houses so that there won’t be any scarcity for water during the summer time. The church is promoting rain water harvesting to all the members of the parish so that they also won’t suffer due to water scarcity in summer time. It will help the soil to be filled with water. It will be good for the people who are cultivating in their home properties. The Diocese is providing the service of technical experts to those who need it. Rain water harvesting was implemented in CMS LP School, Muhamma, CMS HS Mundakayam and CMS LP School Mallappally.
