Overview
Detention tanks collect stormwater from a property before releasing it into the public system, helping to prevent problems for downstream drains and waterways. In Auckland, where council drainage systems are behind the growing number of houses, detention tanks are often a requirement for newer properties and are becoming increasingly common.
The Issue
Like other stormwater drainage systems, detention tanks will filter out natural debris such as leaves and silt, but these build up, particularly in areas with high amounts of foliage. If a detention tank hasn’t been cleaned in several years, its outlet will eventually block. The next time there is rain, water will flow back out of pipes and cesspits, eventually causing flooding on the property.
How We Fix The Problem
Drain Ninjas can easily fix a blocked detention tank by giving your detention tank a clearing and a clean with one of our vacuum trucks. Once the tank is cleared we will check the outlet line and confirm that the tank is in working order again. We also use the buildup of debris to advise on when your detention tank should next be cleared – generally, this is around once every 5 years.
Drain Ninjas are available for emergency callouts, but in general, we’d recommend having your detention tank cleared and checked before it starts to show signs of blockage, and during a period of low rainfall. Dried leaves and foliage are lighter and therefore cheaper to remove than when they are soaked and accompanied by large volumes of water. Where possible, arranging a detention tank clean in advance avoids possible flooding problems and costs less than an emergency clean.
