Above 200 houses have been recently built unlawfully in Kinawataka that is one of the dangerous swamps, which filter waste water and control flooding in Kampala, a team of wetland inspectors have stated.
According to Joseph Ogwalo, a senior inspector in the wetlands management department, a team of environment experts marking the wetland limits ahead of the expulsion of encroachers, counted the houses. “We have come across many houses illegally built in the swamp. Most of them are permanent and must have cost a fortune to build while others are shacks,” he said.

At last month's Eco-build show at Earl's Court, a few stands were promoting ground-source heat pumps. Heralded as a planet-friendly way to heat homes, they work by harnessing heat energy under the ground.One metre below the surface, the temperature is a fairly constant 10C. In most cases, you end up putting in three units of electricity to get out three units of heat.For homes attached to the gas mains, the heat pumps are usually a waste of money. Most experts agree that if a large source of surplus renewable electricity is available from, say, a medium-sized wind turbine or a micro-hydro system, then they could make sense – but this would cost £10,000 to £20,000.
