WATER & UTILITIES / SITE DRAINAGE
Overflow pit and bund monitoring
Nothing is pumping here, so nothing raises an alarm
Sites are full of places that hold water without any machinery attached: storage and overflow pits, bunded areas around tanks, basements, cable pits, transformer bunds, cellars and simple low-lying corners of a yard. Because nothing is running, nothing can fail, so there is no fault signal, no control panel and no alarm of any kind. Water gets in through rainfall, groundwater, a burst or a leaking bund, and the first anyone knows is a flooded cable pit, a bund holding rainwater that has consumed the containment volume it was built for, or damaged stock in a basement. Where a pumped station at least has a panel that can complain, these locations have nothing.

Overflow pit monitoring: what changes the day it goes live

- Water presence detected at floor or threshold level in places that have no pump, no panel and therefore no alarm today
- Bund capacity protected, because a bund full of rainwater is not available for the containment duty it exists to perform
- Cable pits, transformer bunds, basements and substations covered by the same battery sensors, with no power or cabling at each location
- Escalation out of hours, which is when a slow ingress turns into a flooded asset

The full stack, applied here
All five layers, one accountable system
Every Indiott build runs all five layers as one accountable system. Follow a single live signal from the sensor that catches it to the report that proves it.
Turnkey LoRaWAN and industrial sensors read the physical world at the edge, on battery, without rewiring the site.
Hands a reading to CONNECT ↓
Gateways, industrial routers and serial device servers carry every reading back over LoRaWAN, 4G, 5G, Ethernet or satellite, so the far edge reports as reliably as the plant room.
Hands a signed stream to SECURE ↓
OT security by design: managed switching, VPN and firewall routers, protocol gateways and hardware data diodes keep the network segmented and the data tamper-evident to IEC 62443.
Hands a trusted stream to CONTROL ↓
When you want the system to act, remote IO, wireless valves and the bespoke Indiott Engineering line close the loop, dose, switch, isolate or interlock, with no human in the middle.
Hands an action to MANAGE ↓
The software layer turns it into decisions: live dashboards, mapping, alarming and analytics, with one-tap reports and clean feeds into your SCADA, BMS or existing platform.

How teams start
From a single pilot to the whole portfolio
You do not boil the ocean. Nearly every rollout runs the same four moves, and you own a working, evidenced result at the end of the first one.
Scope & risk map
We walk the sites, list the assets and pin the one constraint that matters, then agree what a good result looks like before a single sensor is bought.
Pilot on one site
A focused set of sensors goes onto one site or asset group, live on our telemetry and dashboards, wired to the people who need the alert.
Validate & standardise
We tune thresholds, kill false positives, confirm the integration into your SCADA, BMS or CAFM, and write the standard design down so it repeats.
Scale the portfolio
The proven design rolls out across the estate, reusing the same hardware standards and data models so every site reads the same way.

Why Indiott
A specialist stack, not a box-shifter
Brand-agnostic by design
We pick the best of each brand for the layer and the environment, not one vendor catalogue. Milesight, AquaIoT, Atop, Browan, SpecSens and Urban.io, chosen on merit.
The whole stack, one supplier
Sensing, connectivity, OT security, control and the dashboard come from one accountable team, so there is no finger-pointing when something needs to talk to something else.
Specified and supported in Britain
UK-based engineers scope the site, quote the kit and stand behind it, with compliance mapped to the regimes your auditors actually cite.
Honest kit, honest pricing
Prices are shown where we can, quoted fast where we cannot, and you get a straight answer and a bill of materials within one working day.
DEPLOYED IN THE FIELD
Compliance this answers to
| Standard | What it requires |
|---|---|
| Control of Pollution (Oil Storage) Regulations 2001 | secondary containment must be available and fit for purpose, which a bund full of rainwater is not |
| Environmental Permitting Regulations 2016 | preventing uncontrolled discharge from site drainage and containment |
| Flood and Water Management Act 2010 | drainage asset duties for local authorities and risk-management authorities |
| DSEAR 1998 | water ingress into pits and chambers in classified areas forms part of the risk assessment |
What it costs, roughly
A monitored pit or bund is a single moisture sensor plus a share of the site gateway, making this the lowest-cost point on this page. Sites usually instrument a dozen locations for less than the cost of one flooded cable pit. Where a pit is pumped, see pump station monitoring instead, which covers the pump and panel as well.
Overflow pit monitoring: asked before buying
How is this different from your pump station monitoring page?
Pump station monitoring is for locations with a pump and a control panel, where most of the value is knowing that the pump or panel has failed. This page is for locations with no machinery at all, where there is nothing to fail and therefore nothing that can raise an alarm. If your pit has a pump, start with the pump station page; the two are complementary and often deployed on the same site.
Does it measure depth or just presence?
The moisture sensor reports presence, which for a bund or a cable pit is the answer that matters, since any water at all is the exception. Where you genuinely need depth, a level transmitter and the loop sensor give a real trend, and we will quote that where the application justifies it rather than by default.
Will it false-alarm on condensation or a damp floor?
Placement is what determines this. Mounted at a defined trigger height rather than flat on a damp slab, it reports meaningful ingress rather than ambient damp. We would rather set that height with you during scoping than have you lose trust in an alarm that cries wolf, because an ignored alarm is worse than no alarm.
