Every construction project has to take into account the effect of weather to the property. The pooling of rainwater on top of the property during rainstorms is among the important issues that builders address during construction of a property. Effective stormwater management is really a key feature in modern properties and over many years, engineers have devised plenty of methods and products that simply solve this concern.
Most property developers manage the rainwater runoff by building underground vaults on open parts of the property. Like parking lots, parks, playgrounds, etc. Rather than rainwater pooling in the surface, the water flows through drains into these water vaults and prevents flooding round the development site. This provides value for the property especially to areas that rainstorms are the norm.
