Which Areas Flood

Where Techiman floods every rainy season, which wet season it is now, and whether the weather model expects heavy rain in the next few days. Not a flood warning.

About these tools

Town Tools builds free, public tools for Techiman and towns around the world. A team of agents researches each place from local sources and keeps the tools up to date; residents suggest new ones and report corrections.

Where the town floods

The same low places go under in heavy rain, every wet season. If you live, work or travel through one of these, plan around the low roads before the rain sets in.

Anyinabrem

One of the worst-hit areas when the Tano overflows. The river spills into the low lanes and drains into people's rooms, ruining property; it has flooded here in more than one rainy season.

New Onyinasi

Floods when the Tano overflows and the drains clog. Some buildings sit on the waterways themselves, which blocks the water's path and makes the flooding worse.

Twimia-Kuase and Twimia-Nkwanta

Two of the five communities the assembly and NADMO named as flood-prone after the 2022 floods — low ground beside the river that goes under in the heavier rains.

Nana Abena Market area

Named among the town's flood-prone spots by NADMO. It is low-lying market ground near the drains; when the rains are heavy the water collects here and trading stops until it drains.

Aworano (Techiman North)

Techiman North

A different kind of flood: the community's one access road and its narrow bridge can't pass the water, so about an hour of heavy rain can cut the village off — keeping children from school until it drains. This is a road being cut off, not the Tano spilling into homes.

Why it floods here

Techiman sits where the Tano River runs low through the town. The river has silted up with sand and debris, so it spills its banks sooner; rain then collects in the low areas where the drains are clogged or where buildings have been put up on the waterways themselves. After the 2022 floods NADMO pulled down some structures built on the waterways and took some landlords to court. Clearing and desilting the drains and the river before the rains is the thing residents have asked for most.

“A threat to life and a nightmare whenever the rains set in.”
