for weeks, dennis rhodes has not been taking any new orders to drill wells. he already has a two-year waiting list. the groundwater is being tapped deeper and deeper. the level continues to sink. more and more wells are drying up. >> it's probably been the worst on the private households because a lot of people cannot afford to drill deeper wells. there's basically too many straws in the ground and everybody's racing to get deeper so they can keep their crops growing and make some type of profit off of their farming operation. >> the authorities do deliver water to some affected but without the help of volunteers like donna johnson, it would be far too little for many families. some days, donna is on the road until late evening. the beltrans are one of the families she regularly supplies with fresh water. but ultimately help can come only from above, in the form of rain. they pray for it every night, like everyone in the valley. and that's all we have time for on this edition of global 3000. for more facts and analysis please check out our website. and rememb
