In a small suburban development on the far western outskirts of Sydney’s urban sprawl, the city’s first suburb-wide, privately owned decentralised wastewater reuse scheme is about to start construction. The development is Vermont, in Pitt Town.
The privately-run scheme will collect sewerage from 900 houses and deliver third-pipe recycled water back to the same homes for a slightly lower price than the state-owned utility currently provides drinking water. The scheme will operate under a new regulatory frame-work specifically designed to encourage new market entrants, and I would imagine that it could be highly profitable, given that they will be collecting sewerage rates on top of the price of the recycled water but only have to run one plant. I suspect that the cost of constructing and maintaining a third-pipe is not dramatically higher than maintaining two.
No doubt the recycled water will be plumbed directly into the toilets and gardens of the homes before purchase, so they have a captive market.
Small scale reuse schemes seem likely eat away at the market of major utilities by providing decentralised solutions to outlying suburbs and small communities. The major utilities are vulnerable in the locations where pumping distance and geography erode the efficiencies of large centralised plants.
If the population ever accepts recycled sewerage as potable water then the decentralised business model becomes dramatically more compelling. If you can bundle in stormwater harvesting then you are really talking.
It seems to me that if the major utility business are able to create divisions that specialise in operating and maintaining decentralised schemes, then there is no need for them to lose that market share to smaller players. For better or worse I think that they are unlikely to do this. Large utilities tend to be big, lumbering, heavily unionised beasts that are impossible to steer and which crush innovation.
A smart utility executive interested in entering a more lightly regulated market might see an opportunity to create a 100% owned subsidiary with a separate management structure to target these potentially highly profitable opportunities. It would require a far less hierarchical management approach and very lean and very smart operations. They will need to select executives and management who know water and sewer well, but who also have an entreprenurial mind-set and the ability to rapidly innovate.
If they don’t, then they can kiss that market share goodbye.
