Two trucks were converted to tank truck, have the head of the environment Department Rosemarie Holy (Green) and Bernd Roser, head of the Department of the green entertainment at the parks and recreation Department, on Friday presented. You should help for the Watering of young trees in the urban area of less drinking water must be used.
For the supply of approximately 10,000 young trees have been consumed in the past two years, according to the parks Department, respectively, between 22.5 and 25 million liters of drinking water. “We have been mainly from the bird mountain circle often criticized,” says Holy. The irrigation of young trees makes up only about 0.05 percent of the total drinking water consumption of the city. About a third of the water, with the the city the trees watering, also, according to Roser from industrial water abstraction points. The preliminary goal is to increase the proportion to two-thirds. From now on, also the main is below the water. “When the barrels are filled, the vehicles are usually in Central locations in the city,” says Roser. There is a smaller tank be filled with cars going from tree to tree. 100 to 150 litres to get a tree per week, so Roser. With a full tank of the two vehicles up to 60 trees can be poured.
“basically, it is shameful”
Up to five years after planting, urban trees have to be watered according to the parks Department usually in extreme locations, even to the tenth year. In a joint statement, four environmental groups had criticized in October last year, the city of Frankfurt for a “ruthless drinking water is a waste”. Each year, 40 to 45 million cubic meters from the bird mountain circle be headed to Frankfurt – more than a third of the total needs of the city. And, although the low damage to ground water levels in the Central mountains of the nature. Was one of the signatories of the Declaration, the protective Association of bird mountain. The scientific Advisor to Hans-Otto Wack, not been able to gain the new tanker much. “You can leave it as a Demonstration of good will to go through,” he says on Friday afternoon on the phone. Anything needed to make the city Yes. “But basically, it is a shame that the city didn’t come 25 years after the first plans for a water system, especially when you consider the promises of the last four years.”
800,000 litres of drinking water to replace the new tank cars per year. The amount of Drinking water that was consumed in the past two years for the tree irrigation are the three to four percent, which can be saved immediately. “So you won’t get far,” says Wack. He calls, from the Main water pipes and cisterns, dig, where more hot water is kept can be. Even if a new tank is between 20,000 and 40,000 euros could cost: “That would be an investment for generations and would pay for itself over time.”
