In climate change, having a second water tank can prove advantageous. With the increasing frequency of extreme weather events, including droughts and unpredictable rainfall patterns, a second water tank provides an additional storage capacity to collect and store rainwater during abundant rainfall.

Amplify Your Rainwater Resilience: Climate Change Calls for a Second Water Tank
Climate change makes extreme weather more extreme.
Extreme weather has always existed: heavy rain, heat waves, floods, and droughts. Nowadays, these extreme weather events are directly linked to climate change. However, an international team of researchers has published a study in the journal “Science Advances” on the extent to which climate change is responsible and what scenarios are possible for the future. According to the study, the world will probably have to prepare for more unstable climatic conditions and extreme weather events. Two-thirds of the world’s mainland will face wetter and more changeable and unpredictable weather. Some regions, on the other hand, will have to reckon with longer-lasting droughts.
Warning Signs: Auckland floods herald future challenges.
In New Zealand, we are already looking back on a few extreme weather events in 2023. At the end of January, torrential rainfall had caused landslides and flooding in the region around Auckland. At that time, rainfall amounts usually measured in the entire summer had fallen within a few hours, according to the National Research Institute NIWA. Authorities called it the “wettest day” since records began.
Two weeks later, Cyclone Gabrielle battered northern New Zealand with heavy rainfall. In some places, three times the usual monthly rain fell in one night. Flooding and power cuts resulted, and a state of emergency was declared. The torrential rains in New Zealand triggered by Cyclone Gabrielle mainly affected Auckland and the regions of Northland, Tairawhiti, Bay of Plenty, Waikato and Hawke’s Bay.
Cyclone Gabrielle also had severe consequences because many grounds in northern New Zealand had already been softened by record rainfall a fortnight ago. Disaster researcher Christine Kenney of Massey University warned that New Zealand had entered an era of “cascading natural disasters”. Climate scientist Daithi Stone explained that “Gabrielle” was so intense because of the current particularly warm sea surfaces, which are due to the climate phenomenon La Niña and global warming.
Prevention is better than cure! Top up your Water tank capacity by installing another rainwater tank
While Australia has been struggling with new natural disasters and extreme weather due to climate change for a long time, such severe weather events have been the exception in Aotearoa. However, in 2023, natural disasters in New Zealand have become more frequent. At present, the North Island is repeatedly hit by days of continuous rain. Floodwater stands on the meadows, the rivers carry muddy water, and the water tanks are filled to the brim. Right now, it is hard to believe that next summer might hold a drought in store.
But what if next summer is one of the hottest and driest in New Zealand? What if it doesn’t rain for several weeks or even months, as is currently the case in Europe? In 2017, a prolonged drought in Northland parched the soil and depleted many water tanks. In April 2022, the Cosseys dam in the Hunua Ranges was at about 50% capacity during a drought in the Auckland region.
In the past, local regions like Mangawhai, Mangawhai Heads and surroundings have already suffered from less rainfall during the warmer months. Water shortage has led many households to get water from water carriers. An additional water tank increases your water capacity and helps to avoid extra costs while being more independent.
Climate change challenges ahead: Stay independent with a rainwater harvesting system
Having a rainwater harvesting system in times of climate change makes sense for several reasons:
1.Water Conservation: Climate change can lead to unpredictable weather patterns, including droughts and water scarcity in certain regions. A water tank allows you to collect and store rainwater during rainfall, ensuring a reliable water supply during dry spells. It promotes water conservation by reducing reliance on traditional water sources and alleviating the strain on local water systems.
2. Resilience and Self-Sufficiency: Climate change can bring extreme weather events like storms or floods, disrupting regular water supply systems. By having a water tank, you create a backup water source that can sustain you and your household during such disruptions. It enhances your resilience and self-sufficiency, ensuring access to clean water even during challenging times.
3. Sustainable Water Use: Climate change often emphasises the need for sustainable practices. With a water tank, you can harvest and utilise rainwater, a natural and renewable resource. This promotes sustainable water use by reducing reliance on treated or potable water for non-potable purposes like irrigation, gardening, or cleaning. It helps conserve valuable drinking water resources for essential uses.
Environmental Impact: Water tanks contribute to reducing the overall environmental impact of water consumption. By relying on rainwater, you lessen the need for water extraction from rivers, lakes, or underground sources, which can adversely affect ecosystems and biodiversity. Using rainwater also decreases energy consumption associated with water treatment and distribution, mitigating environmental impact.
Climate change looms, act now: Double your rainwater storage for resilience
Getting a second water tank for your rainwater collections system in the light of climate change can provide several advantages:
Increased Water Storage Capacity by adding another rainwater tank
We are experiencing more unpredictable weather patterns due to climate change, including extended dry periods or extreme rainfall events. Having a second rainwater tank allows you to increase your overall water storage capacity, enabling you to collect and store more rainwater during periods of heavy rainfall. The additional storage ensures a greater reserve during dry spells, providing a more reliable water supply.
Enhanced Resilience with a second water tank
Climate change can lead to more frequent and severe droughts and disruptions in regular water supply systems. Adding a second rainwater tank to your system improves your resilience to these challenges. The increased water storage capacity offers an extended buffer against water scarcity, ensuring you have a sufficient supply during extended periods without rainfall or when traditional water sources are compromised.
Flexibility in Water Use
With a second rainwater tank, you have greater flexibility in water use. You can allocate one tank for specific purposes such as indoor use (e.g., flushing toilets, laundry) while dedicating the second tank for outdoor use (e.g., watering gardens, washing cars). This segregation allows for more efficient water management and optimised use of rainwater based on your needs and priorities.
Redundancy and Backup with a second rainwater tank
A second rainwater tank provides redundancy and a backup system. If there is a malfunction or maintenance requirement in one tank, you can rely on the other tank to continue collecting and storing rainwater. This redundancy ensures that your rainwater harvesting system remains operational, even if one tank is temporarily out of service, maintaining your water supply continuity.
Water Conservation and Sustainability in times of Climate Change
Climate change necessitates a greater focus on water conservation and sustainable practices. Adding a second rainwater tank contributes to conserving water resources by maximising rainwater collection. This reduces reliance on traditional water sources and promotes sustainable water use. Additionally, utilising rainwater for various purposes helps minimise the strain on local water systems and supports overall water sustainability efforts.
Choosing the right water tank for your home can be tricky. There are various things to consider, especially when topping up your existing rainwater harvesting system capacity. And from our long-term experience, we know that installing a water tank can hold unpleasant surprises in store. Therefore, play it safe from the start and partner with Aqua Works!
