Dr Kurien Baby, District Collector of Trissur, Kerala, and Solution Exchange Water Community are organizing a regional meeting to discuss the effects of the Mazhapolima program. The dates are 16-17 June 2009, and it will be held in Trissur.

Background

Kerala has among the highest well densities in India, and 71% of the population depends on them for drinking water. The aggregate household investment in the state on wells is pegged at Rs 1800 crore and they have a combined yield potential of 6.6 million cu m per day. That works out to a water availability of 197 litres of water per capita per day (lpcd), well above the government's prescribed norm of 140 lpcd. These wells are threatened. Despite an annual rainfall of 3,000 mm, 70% go dry in summer. The surface runoff is heavy, and therefore groundwater levels in several blocks have fallen sharply, and coupled with saline intrusion at an accelerated pace, have led to water quality problems.

Some of the changes proposed are as follows –

• In section 4 of the principal Act, in sub-section (1), for clauses (a) and (b), the following clauses shall be substituted, namely:-
• the number of wells that were in existence in the scheduled area immediately before the date of commencement of this Act;
• the use of groundwater in the scheduled area for agricultural purposes immediately before the date of commencement of this Act;
• the number of wells from which water is extracted for domestic purposes;
• the number of wells from which water is extracted for industries, automobile service centres, multipurpose halls and other commercial centres;
• the number of water sources both public and private;
  • In sub-section (2), for item (vii), the following items shall be substituted namely:-
  • the details of the methods  adopted for groundwater conservation and rain water harvesting;
  • the quality of water with scientific evidence;
  • such other matter as may be prescribed.
