Running a car wash in Tamale and the north: one rainy season, dust and water

Seven months. From roughly November to May, Tamale sees almost no rain, the Harmattan comes down from the Sahel, and every vehicle in the city is the same colour by lunchtime. For a car wash in Tamale that is the whole year's business compressed into one long season, and the washes that do well are the ones that have water when everybody else is queuing at the standpipe.

The north is not Accra with less rain. The customers are mostly on two and three wheels, the water costs more and comes from further away, and the single rainy season means one long peak and one quiet stretch.

Seven dry months: when the demand comes

From the first Harmattan haze in November until the rains settle in around May or June, dust is constant. A motorbike washed on Monday is brown by Wednesday, and anyone with a wedding, a funeral or a Friday prayer wants the vehicle clean. December, with Christmas, the harvest money and people home from the south, is the busiest month, and the weeks around Eid fill up too.

The business is volume, not price. A wash near the Central Mosque, along the Bolgatanga road or by the main station at Aboabo can wash sixty or more motorbikes on a good dry-season Saturday. Prepare for it the way an Accra wash prepares for Harmattan, with more towels, more water and a drying line; the checklist is in Harmattan is car wash season.

Water in Tamale: the real cost per car

Water is the constraint on everything. GWCL supply from the Nawuni plant on the White Volta is rationed across the city, and in the dry months many areas see it for a few hours a week or not at all. Tankers fill the gap, and in the dry season a load commonly costs GH₵300 to GH₵700 in 2026, more than Accra, climbing in March and April when the river is low. Prices vary a great deal by area and distance.

Boreholes are the answer where the water is reachable, but the ground around Tamale is harder and the water table deeper than in the forest zone, so drilling costs more and the dry-season yield can drop. Get a survey before paying a driller, and plan storage of 10,000 litres or more. The one advantage is that motorbikes and tricycles use far less water than cars, roughly 20 to 40 litres each, so the per-vehicle cost is bearable even when the tanker price is not. The full comparison of supply options is in water supply for car washes in Ghana.

Motorbikes and Pragya are the main customers

In Tamale the motorbike is the family car. Everyone rides, and the yellow Pragya tricycles carry most of the city's passengers. The money is in doing a motorbike well in ten minutes for GH₵5 to GH₵12 and a Pragya in twenty for GH₵10 to GH₵20, with chain lubrication and a seat wipe as standard. Riders bargain hard.

The cars that do come are the Land Cruisers and pickups of NGOs and government offices, the private cars of the city's business families, and long-distance drivers passing through to Bolgatanga and Burkina Faso. Fleet work is worth chasing, because the organisations keep vehicles clean on a schedule and pay by invoice. Lay the bay out with a motorbike line on one side and two car spaces on the other, so the two trades do not block each other. The process and the pricing for bikes is in washing motorbikes, okada and Pragya.

The TaMA permit and the Sagnarigu line

Tamale Metropolitan Assembly issues the business operating permit for the city, with a yearly fee set by its own schedule. Much of what people call Tamale falls under the Sagnarigu Municipal Assembly, which has its own office and fees. Check which side of the line your plot is on before you go.

The sequence is the usual one: ORC, GRA for the TIN, the EPA's Northern regional office if your Assembly asks for it, then the Assembly. Fees differ between the two Assemblies and change each year, so confirm at the revenue office. The EPA in the north is attentive to where wash water goes, because in the dry season it does not soak away and in the wet season it runs into open drains.

Pricing a car wash in Tamale

Everything is cheaper than Accra and the customers expect it. A saloon body wash is commonly GH₵15 to GH₵30 in 2026, a pickup or Land Cruiser GH₵25 to GH₵50, a full wash with interior GH₵35 to GH₵70, a motorbike GH₵5 to GH₵12 and a tricycle GH₵10 to GH₵20. Prices rise a little in December and around festivals and fall in the rains. Post them on a board, because the board ends the bargaining faster than any argument.

The margin is made on volume and on water discipline. A washer who uses a bucket and a cloth on a motorbike and saves the pressure washer for the wheels uses half the water of one who hoses everything, and in April that difference is the profit.

When the rains come

The single rainy season runs roughly from May or June to September or October, and in August the bay can be too wet to work for days at a time. Demand falls and water gets cheaper, which is the time to drill, repair and clean the tanks. Sell mud washes to the pickups coming off the Yendi and Salaga roads and interior cleaning for the damp. Then stock up on towels and chemicals in October, because when the Harmattan haze arrives the queue of motorbikes arrives with it. This month, count how many bikes pass your plot on a Saturday morning, and price a borehole survey before the river is low.
