How Much Does Water Tank Cleaning Cost in Lagos?
Indicative price ranges for overhead, underground and reservoir tanks, and the factors that decide where your quote lands.
This guide covers services we actually offer in Lagos. It separates cleaning and visual checks from specialist diagnosis, explains where a site assessment is needed, and links technical references where they materially support the advice. It is general maintenance guidance, not an engineering or water-safety certificate.
The figures below are broad budgeting examples, not a market survey, fixed Blink price list or binding quote. They can change with access, scope, logistics and parts. The only current price for your job is the written quote confirmed before work starts. Replacement parts, major repairs and new installations are quoted separately.
The short answer
There's no single fixed price for cleaning a water tank in Lagos, and you should be cautious of anyone who quotes one before seeing your setup. What you pay depends mostly on the size and type of tank, how easy it is to access, and how much sediment and sludge has built up since the last cleaning.
As a planning guide, most homes fall between ₦15,000 and ₦70,000 depending on how many tanks they have and where those tanks sit. Underground tanks, concrete reservoirs and estate-scale jobs run higher.
Typical price ranges in Lagos
Single overhead tank
One standard plastic (poly) overhead tank, easy roof or stand access.
Standard home (multi-tank)
Storage + booster setup, two or more tanks, typical access.
Underground / reservoir / estate
Underground tanks, concrete reservoirs or multiple units. Quoted on site.
These are indicative ranges for planning, not a quote. Your actual figure is confirmed after we understand your tanks and access.
What affects the price
Six things move a tank-cleaning quote up or down:
- Tank size & capacitya 1,000L poly tank is quick; a 10,000L+ reservoir is a much bigger job.
- Tank typeoverhead plastic is simplest; steel, underground and concrete reservoirs take more time, tools and safety steps.
- Number of tanksmany homes have a storage tank plus a booster/overhead tank. More tanks, more work.
- Accessa tank on an easy roof or stand is cheaper than one that's awkward, high or tightly enclosed.
- Sediment levela tank cleaned every few months needs far less effort than one untouched for years.
- Location & logisticsdistance and site conditions can affect the quote.
Cost by tank type
| Tank type | Typical range | Notes |
|---|---|---|
| Small overhead poly (≤1,000L) | ₦15,000–₦25,000 | Common single home tank; quick when accessible. |
| Larger overhead / multiple tanks | ₦30,000–₦70,000 | Storage + booster or 2–3 tanks. |
| Underground tank / sump | ₦60,000–₦150,000 | Confined-space care, pumping out, more time. |
| Concrete reservoir | ₦80,000–₦200,000+ | Large volume; estate and facility scale. |
| Estate / multi-unit | Custom quote | Priced per site; best on a maintenance plan. |
How to keep the cost down
- Inspect on a schedule. A recorded review cycle catches sediment before it becomes a larger job. Clean according to condition; see how often to inspect and clean a tank.
- Bundle services. Combining tank cleaning with a pump check in one visit is usually better value.
- Go on a plan. A recurring maintenance plan can work out cheaper per visit and prevents costly emergencies.
- Fix the cover. A sealing tank cover slows down how fast dirt returns.

Frequently Asked Questions
Indicatively, about ₦15,000–₦30,000 for a single small overhead tank, ₦30,000–₦70,000 for a standard multi-tank home, and ₦70,000–₦200,000+ for underground tanks, reservoirs or estates. Pricing is quote-based.
Because tank size, type, access and sediment level vary widely. A single fixed figure would be misleading. We confirm your price after understanding your setup.
Often yes. Regular cleaning means less sediment per visit, and plans can reduce the per-visit cost while preventing expensive emergencies.
