The Law issued by the Congress amended Article 111 of Law 99 of 1993, which had previously been modified by Law 1450 of 2011 and Decree-Law 870 of 2017.
 

This modification declares areas of strategic importance ("ASI") for the conservation of water resources that supply water systems as a matter of public interest. It establishes that territorial entities must allocate, as a mandatory investment, a percentage not less than one per cent (1%) of their current unrestricted revenues for the acquisition, restoration, rehabilitation, ecological recovery and conservation of water resources for municipal, district, and regional water supply systems.
 

It is important to emphasize that this Law incorporates into national legislation the requirement that investments must be made with a focus on Nature-Based Solutions ("NBS"), adaptation to climate change, ecological restoration, or to finance environmental services payment schemes ("ESPS").
 

Additionally, environmental, or administrative authorities must update the inventory of priority areas to be intervened and incorporate them into the Registry of Ecosystems and Environmental Areas.
 

Finally, the Ministry of Environment and Sustainable Development ("MADS") has a period of six (6) months to issue regulations specifying the scope of this Law.
