Stormwater is often confused with rainwater. Rainwater is runoff from roofs, while stormwater is collected from drainage points. Unlike rainwater, stormwater requires a longer sanitizing process. The stages in stormwater utilization include harvesting, treating, storing, and reusing.
Successful harvesting of stormwater requires efficient drainage systems. Areas that receive heavy rains require wider and stronger drainage systems. The different types of drainage systems are:
Slot Drains
They are the newest trend in drainage technology. They are ideal for outdoors but are narrow and can flood easily in places that experience heavy rains. Hence, they are ideal for places that experience little rain. They can withstand pressure from car tires and footsteps.
Open Storm Drains
They are uncovered storm drains situated by roadsides or near the edges of properties. Open drains are expensive to install but cheaper to maintain. They require fencing since their open nature poses a threat to pedestrians and animals. Improper draining of the water causes a stench and can harbor mosquitoes. However, they are ideal for places that experience heavy rains and are easy to clean.
Closed Storm Drains
They are efficient and safe but are difficult to clean. They clog easily, especially if the drainage water originates from a place with garbage or thick soil. They do not impede land use as you can grow grass or flowers over it.
Water from drains expel into drainage collection points ideal for stormwater harvesting. They are treated and stored for use in flushing, irrigating, drinking, and industries.
