Incentivize people to build/restore wells. Make it easier for farmers to build water reservoirs, without allowing this to be used to build swimming pools in ODZ. Incentivize swimming pool owners to use salt water rather than chlorinated ground water. Come up with a strategy how to help the water table to be replenished. Some ideas how this can be done: fund the diversion of roof drain systems to the ground rather than to the streets or the drainage system; and build/restore small dams in valleys to allow the water to soak through the rock. Embellish public gardens and roundabouts with plants, shrubs and trees that do not require heavy watering.
