Water is also a rights issue. As the global population grows, there is an increasing need to reconcile competing commercial demands on water resources, so that communities have enough to meet their needs. It is worth noting that women and girls must have access to clean, sanitation facilities that respect their privacy, in order to manage menstruation and for them to have a dignified and safe maternity.
Human development requires water and sanitation systems to be carried out separately.  Both are vital for reducing the number of diseases and for improving the health, education and economic productivity of populations.
