Storm water drainage solutions

Whether you are an operator of an industrial facility or a construction site, you are required by law to implement storm water drainage solutions that fully comply with NPDES regulations. The purpose of these regulations is to limit the effects of storm water runoffs. While the NPDES regulations were created to reduce the impact of storm water runoffs on the environment and the community, the importance of adopting an efficient drainage plan is undeniable. You can resort to specialized help such as for a quality SWPPP narration. Converting undeveloped areas to habitable land results in numerous environmental and health issues because the new impervious surfaces do not allow rain water to infiltrate in the ground and it gathers on the surface in large amounts. The resulted storm water can pick up pollutants and flow into water bodies. The effects of pollution are disastrous, because people use the water for drinking, swimming and fishing, which is a major issue for the whole community. Water runoffs can gather and carry sediments inhibiting plant growth, excess nutrients boosting the algae population, bacteria and pathogens putting the health of humans and animals at risk, debris and household hazardous wastes suffocating and poisoning aquatic life. Storm water drainage solutions are a set of preventive measures that can drastically reduce not only the chance of a storm water runoff, but also its negative effects. Here are the most common ways to dispose of rainwater: storm water sewers, storage tanks collectors and soakaways.


Storm water channels

In urban and densely built up areas, storm water sewers are absolutely mandatory, as they serve to take the drainage from buildings, paved areas and courtyards. When constructing a building, the drainage from any paved or enclosed area should be discharged into the storm water channels laid alongside the road. Connecting drains need to comply with requirements and NPDES regulations to ensure they are functional. If the drainage pipes connecting to the city system is not compliant and incorporated into the code of practice, it can obstruct the flow of the storm water and cause a disaster. For instance, the drain needs to have a self-cleansing gradient.



The use of soakaways is not mandatory, it depends on the nature of the soil and the expected intensity of the rain. They are basically holes that lead to the subsoil, which are filled with hard materials that will not soften or dissolve when wet such as broken concrete, stone and brick. In some cases, soakaways are not a relevant storm water drainage solution, because it needs to be clear of the foundation of the building to ensure it will not affect it, not to mention that some types of soils do not work well with soakaways.


Rainwater tanks

This is an ingenious solution for owners that wish to use rainwater. However, tanks that collect water for domestic use need to be constructed according to regulations from waterproof, insectproof and verminproof materials. What is more, the tanks need to be properly ventilated and offer easy access for regular cleaning and inspection. Collecting water from storms has its own risks, so regulations are harsh, but once these standards are met, the water tanks can serve multiple purposes.
