Of course, ideally the federal government could help producers install irrigation basins; it could better manage the coherence between municipal and agricultural water supplies.
In Laval, some producers are simply connected to the city's aqueduct network. The federal government could play a coordinating role in infrastructure to ensure that water system planning takes into account producers' access to water, or that infrastructure is planned so as not to affect groundwater quality.
This would be particularly necessary in the case of mines or other projects that take place on agricultural land. There are also a host of laws that could protect adjacent producers' access to groundwater.
