One of the drawbacks with water storage is the risks of bacterial and algae growth. However, this condition occurs after several months of stagnation. A change in odour and taste of stored water in sealed tanks indicate poor water quality. In some regions of Australia, people store surplus rainwater in underground tanks and use them during dry seasons. Also, large underground reservoirs for water are used for irrigation and livestock farming. These are some benefits of storing your water in sub-surface tanks.
For Future Use
In drought-prone communities, governments use water reform and conservation laws to sustain human activities and sustain commercial activities. Usually, large water reservoirs are installed below the ground for many months during the period of low levels of rainfall. This proactive technique ensures that water doesn’t evaporate or face regular challenges like water loss in above-ground storage tanks. When cities store water in underground chambers; it helps farmers, and livestock owners to plan their operations.
Increases Water Security
In Australia, underground reservoir technology helps to enhance water security. Even in countries with desert terrains like Algeria and Saudi Arabia; these underground water-storage systems have been constructed from dunes. However, the earliest type of underground reservoir technology was used in Europe (the Netherlands and Belgium) many decades ago. Also, the idea of storing potable water in a chalk aquifer by the British government was explored after the infamous 2006 drought. Since water security is important, people are devising new applications of underground water-storage technology.
Prevention of Vandalism
Apart from humans, animals might vandalize plumbing fixtures in livestock farms and zoological gardens. Above-ground tanks and their pipelines could be affected by the movement of these animals. So, underground tanks are ideal in these environments because burying the tanks will prevent animals from damaging them. Also, when there’s civil unrest like riots or protests; it’s hard for people to vandalize or tamper with water tanks that have been stored underground.
Protects the Tank from Wild Fires and Hurricanes
Apart from encroachments in from animals and people; keeping water tanks below the ground protects them from fires. In Australia where bushfires occur annually, many smart homeowners that live in the countryside prefer to install underground water storage tanks. It reduces the risk of damages from wildfires and other natural disasters.
Promotes Water Conservation
Conserving water for household, office, agricultural, and wildlife use is a cost-effective option for everyone. When homeowners rely on regular municipal water supply, the pressure might fail to push water into overhead tanks. However, underground water storage tanks have low profiles that allow rainwater to be harvested easily.
To Recycle Wastewater
Water loss prevention with underground tanks can serve non-potable purposes like irrigation and greywater recycling. Usually, on-demand irrigation systems help to sustain crops and livestock. Since underground water tanks can be used to recycle wastewater, they can also store filtered water.
By controlling the distribution of non-potable water, both farmers and homeowners can optimize the use of recycled water. Generally, rainwater harvesting conserves water and prevents runoff that causes soil erosion. When you direct rainwater runoff into underground water storage tanks, it protects the ecosystems and wildlife from the effect of floods.
Water Collection and Reuse
Water loss prevention at home with underground tanks can increase storage capacity. Usually, air conditioners and HVAC system produce water from condensation. The contamination level of these runoffs is often low. So, smart homeowners can ask plumbers to connect hoses to underground tanks that can collect these runoffs for reuse. These runoffs can serve as non-drinking purposes like washing cars, landscaping, and flushing of toilets.
