Water Business<\/strong><\/span><\/em><\/p>\n

800 billion USD \u2013 this is the market size of water infrastructure-related business\u00a0globally [1]. I believe water business has both scale and\u00a0social impact. In this traditional, relatively conservative industry, digital transformation has potential to offer a solution to one of the most important issues in the\u00a0industry \u2013 aged water networks.<\/p>\n

When I heard of \u201cwater business\u201d for the first time, I imaged a fancy water treatment plant, such as a huge-scale desalination plant.<\/p>\n

\"desalination-plant-image\"<\/a>\u00a0[2: Al Jubail, Phase II in Saudi Arabia]<\/p>\n

However, surprisingly, water network, which is invisible in most cases because they are buried underground, shares more than half of total water CapEx market (i.e. many a little makes a mickle\u2026). Water network looks less fancy, but is arguably as important as water treatment plant.<\/p>\n

Underground Water Network Market<\/strong><\/span><\/em><\/p>\n

So, what is water network market like?<\/p>\n

Intuitively, I thought at first water network market would be about emerging economies where water infrastructure has not been sufficiently installed. However, statistics shows counter-intuitive fact: although emerging economies share a certain share in this market, the majority of business is in developed economies (note: China\u2019s water coverage rate (83.9%) is as high as other developed economies [5]).<\/p>\n

\"network-market-by-geography_2016\"<\/a>[6]<\/p>\n

In fact, water network in developed economies is facing ageing infrastructure under severe constraints on capital at municipality level. Much of the existing pipe network across Europe and North America was laid in the early 1900s in response to population and urbanization at that time.<\/p>\n

After 100 years, it is estimated that US needs to invest for water network refurbishment about $247.5 billion (!)<\/strong><\/span> (of total $384.2 billion in overall water infrastructure) between 2011 and 2030 [7].<\/p>\n

Tragedy from Ageing Water Network<\/strong><\/span><\/em><\/p>\n

Ageing water network reminds me a couple of incidents which happened in the US during a past few years: water main burst in Los Angels (where 93-year old water main burst), as well as Flint contamination (although there are multi-faceted aspects in this incident, one of the important technical aspects was ageing water network which is vulnerable for lower-quality raw water). Those two incidents tell us how important it would be to take care of ageing infrastructure in the US (and in other developed economies), too.<\/p>\n

Maintenance & Rehabilitation of Water Network<\/strong><\/span><\/em><\/p>\n

Traditionally, water network maintenance has been done manually (see a photo below for typical detection work). Employees looked for water leakage using detection equipment without much clue about where the leakage is, often only after a major water disturbance occurred. However well-trained technicians could be, locating leakage point is tough (imagine yourself trying to find an inch-sized leakage point in Spangler Lawn).<\/p>\n

NEC, Japanese IT Company, Goes to Water Market<\/strong><\/span><\/em><\/p>\n

NEC found this inefficiency could be solved by introducing a combination of sensor, wireless base station, and cloud system which is equipped with a unique leakage analysis engine and a leakage-fixing service application.<\/p>\n

1) Leakage analysis engine:<\/strong> Conduct correlation analysis among multiple nearby sensors to locate the leakage point with precision with +- 1m error.<\/p>\n

2) Leakage-fixing service application:<\/strong> Based on the information from leakage analysis engine, provide leakage detection technicians with locations of sensors on Google Maps with leakage points colored based on their \u201cleakage score\u201d (probability of leakage occurrence). This app also supports technicians by providing historical maintenance record for each point, and helps to write their daily report. [11]<\/p>\n

In addition to leakage maintenance, NEC is working on further development of this cloud system to accurately estimate water pipes\u2019 condition based on the information from sensors, geological conditions, material specification of pipes, and the number of years since their installment.\u00a0[12] This estimation will be extremely valuable for water utility companies to prioritize its capital expenditure programs.<\/p>\n

US Market – Largest Potential<\/strong><\/span><\/em><\/p>\n

Aware of US\u2019s huge market potential, NEC started its sales activity in 2015. The first client has been the City of Arlington, Texas. NEC installed a series of 33 sensors at 2 main sites in Arlington water system, finding and fixing 3 leakages during 4-month trial. [14]<\/p>\n

My Recommendations<\/strong><\/span><\/em><\/p>\n

So, where can NEC go from here? It seems to me that technologies and ideas are working; so, the question is how to build a viable business model. In this regard, my recommendations are as follows:<\/p>\n

1) Revenue sharing business model<\/strong>\u00a0– NEC should propose a fee structure with initial payment to (partly) recoup its sensor cost, and a profit-sharing model based on pre-agreed metrics.<\/p>\n

2) Partnership<\/strong> – Tie-up with local water engineering companies which have strong relationship with utility companies.<\/p>\n

3) Local involvement<\/strong> – Standardize sensor manufacturing procedure so that local manufactures could also play a role\u00a0of supply chain. In my previous experiences, water network industry is highly localized; many utility companies prefer to use local companies for political reasons. Since preventing leakage\u00a0could potentially lose local contractors\u2019 job to fix it, NEC should consider providing opportunity for local contractors to enjoy some benefits.<\/p>\n
