An effective technique consists of separating or diverting clean stormwater as much as possible to minimize the amount of stormwater that needs to be infiltrated or treated making your system much more efficient. One example would be a series of channels and/or pipes that captures runoff above an urban area thereby diverting that 'clean' stormwater into a low area such as a wetland, marsh or other type water body making sure of course that the receiving body can effectively manage those new inflows.
Green Infrastructure (GI) technique Once in the project, we combined the use of permeable pavements, green roofs and rain gardens to manage stormwater effectively. This resulted in a 75% reduction in surface runoff. Our strategy involved: Transforming rooftops into lush gardens, we reduced stormwater runoff and controlled water accumulation across terrains. Replacing traditional pavements with permeable ones assisted in replenishing underground- water levels. This eco-friendly approach reduced stormwater management costs and the potency of the urban heat island effect. Additionally, permeable pavements downsized the amount of pollutants entering waterways by filtering out impurities. With the above strategy, we were able to manage stormwater runoff while enhancing the aesthetics and biodiversity at the project location.
As the founder of Glow Path Pavers, I have experience in stormwater management and sustainable landscape design. For a recent commercial project, we implemented an innovative stormwater harvesting system that captured and stored rainwater for irrigation. By installing underground storage tanks and a network of pipes to redirect water from rooftops and paved areas, we were able to harvest over 200,000 liters of rainwater annually. Compared to using potable water for irrigation, this system reduced water usage by 80% and decreased municipal water bills. We used pervious concrete for pathways to allow water to infiltrate into the ground, reducing runoff. Permeable materials and rain gardens also filtered pollutants before water entered the storm sewer system. Overall, taking a holistic approach to stormwater management through harvesting, infiltration, and filtration created a sustainable solution.
