Drainage-as-a-Service · Lagos

Stop paying for callouts. Start paying for drainage that works.

FlowGuard manages your estate's drainage infrastructure on a fixed monthly contract — sensors, scheduled treatment, and a written response SLA. If the drain fails, we fix it. That's the agreement.

The model

Three layers. One managed service.

Monitoring triggers prevention. Prevention reduces intervention. When intervention is unavoidable, our own dispatch equipment is standing by.

01

The Sentinel Network

Solar-autonomous IoT nodes deploy across your drainage infrastructure. Real-time flow velocity and water level data with threshold alerts before anything reaches critical.

Monitoring layer
02

Bio-Treatment Dosing

Scheduled application of industrial-grade, non-corrosive enzyme formulations. Breaks down FOG at source and prevents the sludge accumulation that causes most blockages.

Prevention layer
03

Heavy-Plant Dispatch

When a blockage exceeds preventive treatment, we dispatch our own dedicated heavy-plant response unit — not a subcontractor's number. SLA-governed timeline. Every time.

Response layer
Service tiers

Built for different risk profiles

From monitoring-only to full risk transfer. All contracts start with a free site audit — no pricing is issued without one.

Audit-first policy Pricing is determined after a free diagnostic audit covering topography, baseline siltation levels, and infrastructure connectivity.

Where we operate

Deploying first across three Lagos corridors

We're onboarding our first pilot partners. If your estate is in these areas, we're ready to have a conversation.

Extreme flood risk

Lekki / Ajah Corridor

Lagos's fastest-growing residential density — and its worst-managed drainage. September 2025 alone saw multiple 7-hour traffic standstills.

High flood risk

Ikoyi / Victoria Island

High-value infrastructure, high-value consequences. The 2021 tidal compound event caused ₦380bn in damage in this corridor alone.

High flood risk

Ikeja GRA / Maryland

Commercial and residential overlap creates compounding risk. The Olatunji canal breach in September 2025 cut off Maryland from Mende.

Why we're building this

Nigeria's first drainage infrastructure operator

FlowGuard came out of a simple frustration: the existing model makes no economic sense. Estates call a contractor after something floods. The contractor shows up, clears the drain, invoices, and leaves. Six weeks later, same problem, same call.

The incentives are inverted — contractors earn more when things fail more often. We built FlowGuard to flip that. A monthly contract where our revenue depends entirely on your drainage working.

A Stratum Infrastructure Group company

Not reactive

Scheduled treatment and IoT monitoring prevent most incidents before they occur.

Not invoice-based

Fixed monthly contract — our revenue doesn't grow when your drains fail.

Not a promise

Written SLA with defined response times and consequences for missing them.

Pilot stage

We're accepting our first pilot partnerships now, and will grow around real results.

If your estate floods every wet season, we want to talk.
