Still, this significant increase in public spending for the water sector has not solved all the challenges. For instance, properly operating and maintaining water infrastructures is less costly than rebuilding them, due to decay, once the community can no longer access the service. Furthermore, closing unlicensed wells is usually more effective than mitigating the consequences of illegal water use, and technification of irrigation systems is also costly, but fails to contribute to water policy objectives if the water saved is used to irrigate additional surfaces.
