SelTank: Supporting Spill Reduction
Through Smart Temporary Storage
SelTank is Selwood’s smart, modular storage
solution designed to help manage excess
wastewater flows during storm and high-risk
events. Using a Programmable Logic Controller
(PLC) system with live monitoring, telemetry and
reporting, it automatically stores excess flow when
a site is under pressure and returns it safely when
capacity becomes available again.
The solution was developed in response to growing
pressure on water companies to reduce storm
overflows, protect rivers and bathing waters, and
improve environmental performance. SelTank gives
operators a practical way to reduce spill risk while
longer-term capital solutions are developed and
delivered. It also provides valuable operational data
to help customers better understand site behaviour,
support planning and identify wider optimisation
opportunities.

As well as helping reduce spill frequency and
pollutant load, SelTank supports compliance,
resilience and faster intervention at high-risk
sites. Its modular design means it can be deployed
quickly, scaled to suit site requirements and used
for both short-term and long-term scenarios.
