Why your business needs a water continuity plan – and 4 ways to put one in place

THE world’s sources of water supply are under immense stress and the impact of water shortages are debilitating cities, organisations and communities every day. It is estimated by 2025, no fewer than 25 of the 48 countries that are expected to be facing water shortages will be African.
That’s according to Mannie Jnr. Ramos, CCO of Abeco Tanks, who said, “This means that around 230 Million Africans will be living in water scarce areas, with another 460 Million in water stressed areas”.
“One of the problems we face is that attitudes to water are vastly different; on the one side you have those who experience an endless supply and take water for granted – mostly living in urban areas - versus those in rural areas whose access to water is limited – they use water sparingly, often having to travel long distances on foot to get it.
He said the attitude of water as an endless commodity has to change.
“We cannot afford to wait for tomorrow or the next crisis. The biggest challenge is that by the time a water shortage hits, it is often too late. There is either no water to use, or limited water availability. This puts a massive drain on existing water supplies as people rush to buy and fill storage tanks. It is therefore imperative that everyone develop and implement a water continuity plan, or the impact will be disastrous, such as happened in Cape Town, South Africa in 2018.”
He outlines four strategies that need to be implemented to help businesses, industry, governments and communities plan for water continuity – educate, conserve, store and reuse.
Strategy 1: Educate
Educating your employees, stakeholders and community around water as a precious resource – like money or gold - is critical to the success of any continuity plan. Ensure staff are trained on water conservation, reuse and storage. Put up signage of water usage tips in areas where water is used. Have a water policy and include water conservation as an agenda point in meetings.
“If attitudes to the way water is used do not change, the long-term success of water conservation initiatives will fail. The only way we will get true behavior change is by shifting how people view and use water.”
Strategy 2: Store water in a water ‘bank’
Water storage in ‘banks’ - that is tanks – act like a savings account so that organisations have the water they need to keep running, in times of a water shortage. For example, a 20 000-litre tank can supply water for seven days, based on an average sized business and depending on consumption. The capacity of tanks varies from 20 000 litres up to 10 million litres, providing options for small to large facilities.
“With a storage tank, businesses, B&B’s, essential medical services such as Doctors and clinics – basically any facility that requires water to operate - can remain open for a period of time,” says Ramos. “Actively storing municipal water in a tank ahead of time and not waiting until there are shortages, assures continuity and does not place unnecessary stress on a city’s infrastructure at the time of a water shortage.”
Strategy 3: Implement systems to reuse water
Recycle natural water resources. Technology is advancing rapidly for desalination and wastewater recycling systems and should be investigated at Government level by every country in Africa. A country that has addressed the problem of water scarcity with innovative solutions is Israel: from hi-tech gadgetry that finds water leaks in pipes; desalination water production plants which in 2014, supplied about half of Israel’s drinking water; and the purifying of sewerage of which 85% gets reused for agriculture.
Install greywater recycling systems. Greywater is wastewater (excluding toilet wastewater) that is generated after using municipal water at an office building, manufacturing operation or warehouse; the greywater is recycled for use in toilet flushing, irrigation or landscaping.
Ramos said these systems are mainly practical for new buildings as most architects have not designed plumbing to accommodate recycling systems. Once the plumbing is in, one cannot reroute water easily which makes it expensive.
“It is worth doing the investigation to see if there is a possibility of recycling in some way, no matter how small or big: every litre saved counts.”
Recycle rainwater. Harvest rainwater from the roof of a building into a water tank for recycling to toilets, basins or irrigation.
Strategy 4: Institute water conservation initiatives
There are many ways one can conserve water in their place of employment – whether it is in an office building, manufacturing facility, farm, school or town – the methods are all tried-and-tested and will significantly reduce the amount of water used.
Check for leakages: Leaking taps, toilets and pipes are responsible for 60% of water wastage, so ensure leakages are constantly checked and fixed rapidly.
Check the consumption: If the water bill goes through the roof, there is something wrong.
Maintain the plumbing: Make sure toilets don’t run or that taps are not left open.
Install water efficient taps with flow restrictors like aerators. In the long term this saves up to 50% of water usage.
Replace single-flush toilets with dual-flush toilets. This saves up to 80% of water usage for flushing. Replace old toilets: Use lower volume cisterns to reduce the flush size.
