Start-ups are investing money in making water services more efficient. But, asks Bob Cervi, where is the funding coming from and who will profit?

In a world where water is becoming increasingly scarce, venture capital (VC) investors are beginning to sit up and take notice. They are putting their money into technologies that promise to increase the efficiency of water services, thereby cutting costs, reducing energy consumption and offering potentially strong returns on their investments.

According to analysts Global Water Intelligence (GWI), around $237 million (£146 million) of venture capital funding was invested globally in water technology companies in January to August this year. Levels of investment ranged from £160,000 to £37 million – with companies developing membrane filtration to treat wastewater at both ends of the scale. While funding is focused on Europe and North America, there are also signs that Asia is becoming a growing water technology market. GWI notes that industrial corporations, such as BASF and ABB, are increasingly investing in water technologies. Extractive industries (oil, gas and mining) are also showing an interest in water, says the London Environmental Investment Forum. It estimates that these heavy water users are responsible for more than £246 million of funding for water technology companies over the past five years.

Why this upsurge? For a start, investors recognise that, all over the world, water is becoming a scarce resource. At the same time, there is growing publicity surrounding waste from leaking pipes, prompting consumers to question why they should restrict their use, and shifting the spotlight to inadequate infrastructure. Helge Daebel of Switzerland-based Emerald Technology Ventures, a VC that invests in water-industry start-ups, also remarks that more start-ups are coming forward now than when he started taking an interest in water around six years ago. He believes this growth has been largely driven by the availability of know-how and talent from other industries, such as IT. Software developers have realised that automated control systems that can be applied to water networks and make even leaky pipelines more efficient. Many specialist software solutions for managing water networks are spin-offs from IT companies or university research departments. One successful start-up, TaKaDu, was set up by experts in the IT and telecoms sectors who had not previously worked in the water sector [see box].

But is the flow of money sufficient to fix the problem, and are VCs the best source? Jacob Tompkins, Managing Director of WaterWise, an independent body that promotes efficiency, affirms that the water market offers great returns for investors. But he feels that the involvement of only a few specialist VCs (such as Aqua Resources, Emerald, Ombu, Pictet and Swarraton) pursuing short-term returns means the sector is still a long way from unlocking the full potential of efficiencies and savings that can be made.

Big investment firms have the means to pour a great deal more cash into the sector, says Tompkins, but they won't do this because of their short-termism: "Investment in water supply and other services can make huge amounts of money but the problem is that the big investment funds aren't doing this because it would mean a payback period of 20 to 30 years. But we do need big investments from these funds, for the long term, if new technologies are to make a real difference in delivering significant sustainable innovation."

Tompkins argues that, in the UK, a government-backed, public-private 'water fund' would help to generate the big investment needed to significantly improve water infrastructure. But there is no sign of support from the Government for such a fund yet.

Nevertheless, VC-backed water start-ups have helped utility companies cut waste and increase the efficiency of their networks, and have now taken their technologies to other continents [see box]. Some utilities are also spotting the potential of working alongside start-ups.

For example, Anglian Water has set up the Water Innovation Network (WIN) to spot potential solutions among the newcomers as well as the more established supply chain companies. WIN manager Vaibhav Tyagi says that about 150 submissions from start-ups have been considered to date, with around four or five of these going on to trial/exploitation stage.

One start-up that Anglian is already with working with is i2O Water [see box]  Adam Kingdon, its co-founder, believes that water companies are getting better at identifying and responding to innovations from new organisations. He says i2O has doubled its sales figures in each of the past three years, with annual revenues now around £5 million.

Given the structure of the utility sector in the UK, water companies can't do all the research and development that a commercial business might undertake. To stay ahead of the game, they need creative partnerships with more nimble companies. WIN is now helping such companies to see their solutions rapidly implemented by utilities, thanks to new fast-track frameworks.

"Anglian Water has an innovation department, which collaborates with other utility companies as well as the supply chain companies, and there are industry-wide initiatives for this", Tyagi explains. Enough change to herald a new wave of collaborative innovation? Watch this space.

From start-up to global operator

i2O Water
In 2006, i2O's founders received funding from angel investors (individuals or groups looking to fund start-ups). It later won backing from a consortium of VCs led by Swarraton Partners. Its smart water grid technology was initially taken up in the UK by Severn Trent Water and Yorkshire, and is now in use by 14 other UK water companies. There are also over 900 installations in 20 countries outside the UK.

i2O offers IT systems to monitor and automatically adjust pressure in water networks in response to fluctuating demand. The process is claimed to reduce system leakage by an average of 20%, and pipe bursting by 30-50%, while customer minimum pressure requirements for water flow are met "99% of the time". Water companies using the process save energy too, as less is needed to pump water around the system.

Bluewater Bio
Bluewater Bio's patented biological treatment system, HYBACS (hybrid bacillus activated sludge), won backing from VC groups Aqua Resources in 2010 and Ombu in 2012. It was first applied to a sewerage treatment plant in South Africa in 2009. A $20 million contract to upgrade and expand a plant in Bahrain followed, and was completed in 2011. In January 2012, Severn Trent Water became the first customer in the UK.

HYBACS offers biological treatment of wastewater from domestic, agricultural and industrial sources. Effluent produced from the system is claimed to be less harmful to the environment than other treatments and can be used to irrigate agricultural land, provide material for landscaping, and reclaim desert land. HYBACS is said to reduce energy use and cut capital investment and operational costs.

Bluewater Bio also acquired start-up firm Water Innovate, a spin-off from Cranfield University School of Water Sciences.

TaKaDu was founded in 2008 by Amir Peleg, an Israel-based entrepreneur who used advanced mathematics and software to increase the efficiency of water networks. With support from VCs including Emerald Technology Ventures and ABB, it now has installations across the world, including one with Thames Water in the UK.

It offers real-time monitoring and reporting of problems arising in water networks – leaks, bursts, flow and consumption anomalies, meter faults and maintenance needs. Water companies can accurately pinpoint and react quickly to such issues as they arise. According to TaKaDu, studies conducted by its customers show a 250-400% return on the costs of the technology, taking into account only measurable direct benefits, such as savings in water or labour costs. Additional benefits include efficiency, better maintenance and meeting regulatory targets.
