Quels sont les moyens les plus efficaces d’améliorer la qualité de l’eau sur les chantiers de construction ?

Effective ways to improve water quality on construction sites include implementing erosion and sediment control measures, using sediment basins and practicing proper waste disposal to prevent soil and pollutants from entering water bodies.

Plan ahead. Before construction begins, develop a plan for how you will manage stormwater runoff and prevent erosion. This plan should include identifying potential sources of pollution, such as sediment, chemicals, and wastewater, and selecting appropriate best management practices (BMPs) to control them.

O consumo consciente, creio ser o melhor cenário. Alertar a todos no canteiro de obras, sobre a necessidade de se consumir esse recurso de forma, que seja adequado a tarefa a ser realizada, assim, como, conscientizar a todos, que este não é um recurso infinito. Pra isso, necessários se faz, um planejamento das tarefas, afim de que se possa dar conta, e tentar prever o consumo de água, para que possamos observar, orientar e agir, sabendo-se de como as tarefas serão executadas, teríamos a possibilidade de prever técnicas e meios, para reduzir o consumo.

Regularly inspect and maintain sediment control systems to ensure their efficacy during the construction phase. Reduce disturbed regions by phasing construction operations and employing interim stabilisation solutions. To increase awareness and compliance, train construction personnel in proper sediment and erosion management practices. Use environmentally friendly construction materials and techniques to limit the risk of water pollution from chemical runoff. Install stormwater management technologies, such as sediment traps and sediment ponds, to absorb and treat runoff before it enters waterways.

Implement BMPs. BMPs are a variety of techniques that can be used to reduce pollution from construction sites. Some common BMPs include sediment fences, silt traps, erosion control blankets, and vegetated swales. The specific BMPs you need will vary depending on the size and type of your project, as well as the local environmental conditions.

Stormwater management: Constructing stormwater management systems like detention ponds or rain gardens to capture and treat runoff water. This helps in removing pollutants and sediments from the water before it is discharged.

Monitor and maintain. Once your BMPs are in place, it is important to monitor them regularly to ensure that they are working properly. You should also make repairs as needed to maintain their effectiveness.

Restore and revegetate. After construction is complete, disturbed areas should be restored and revegetated. This will help to stabilize the soil and prevent erosion.

Seek feedback and improvement. Continuously seek feedback from workers, inspectors, and the community to identify areas where you can improve your water quality management practices.

In addition to these general tips, there are a number of other things you can do to improve water quality on your construction site. For example, you can use water-efficient landscaping, recycle water whenever possible, and properly dispose of construction waste.
