Storm water tanks - reducing excess

摘要

Increasingly, cities and low-lying areas are at risk of sewer overflow from extreme rainfall. Stormwater tanks can help reduce the impact of extreme climatic events by holding back excess stormwater and contaminants. This protects the environment and makes possible the intelligent management of stormwater flows, resulting in savings on infrastructure investments. The concept of stormwater retention is to store temporarily, excess stormwater run-off. This is to avoid hydraulic overload of the sewer system, which could result in the flooding of roads and buildings with untreated wastewater or its release directly into the environment, causing pollution. When space is available in the sewer system, the retained water is released at a rate not exceeding the capacities of the sewer system, and the tank can then be cleaned ready for the next flush.
