Summary

This e-learning session by the Water and Reliable Energy Learning Center (Jasatirta2) focuses on sustainable water management practices, addressing urban development's impact on water absorption. It introduces eco-drainage systems like infiltration wells (sumur resapan) and rainwater harvesting to reduce surface runoff, conserve water, and prevent flooding. These methods not only conserve water but also protect the environment, reduce land subsidence, and support climate adaptation. The session highlights the importance of education and community engagement in promoting these eco-friendly solutions to ensure widespread adoption and environmental awareness.

Takeaways

• 😀 The Learning Center Jasatirta2 focuses on water resource management, renewable energy, and environmental education.
• 😀 The e-learning materials are a collaboration between ITB's Water Resource Development Center (PPSDA) and the Water Enryu Able Energy Learning Center Jasatirta2.
• 😀 Urban housing and settlement development is rapidly increasing, resulting in more impervious land and reduced areas for rainwater infiltration.
• 😀 The old drainage management paradigm aimed to quickly direct water to the nearest drain, which led to issues like flooding, droughts, and ecosystem changes.
• 😀 The new, environmentally conscious drainage system paradigm aims to manage excess surface water by allowing it to infiltrate the soil.
• 😀 The integrated drainage system, known as eco-drainage, seeks to manage excess water by promoting natural infiltration into the ground without overloading drainage capacity.
• 😀 Infiltration wells (sumur resapan) are an example of eco-drainage, capturing rainwater to allow it to seep into the ground and recharge groundwater supplies.
• 😀 The application of eco-drainage techniques, such as infiltration wells, helps reduce surface runoff, which in turn decreases the risk of flooding.
• 😀 Rainwater harvesting systems (Sph) collect and store rainwater for everyday use, reducing the demand for municipal water and providing an alternative water source during dry seasons.
• 😀 Implementing eco-drainage and rainwater harvesting systems contributes to water conservation, reduces soil erosion, and mitigates the effects of climate change.

Q & A

What is the main goal of the Jasatirta2 Learning Center?

The main goal of the Jasatirta2 Learning Center is to provide education and training in water resource management, renewable energy, and environmental sustainability, focusing on preparing competent human resources in managing water from upstream to downstream.

How does urbanization affect water drainage systems?

Urbanization increases the area covered by impermeable surfaces, which reduces the ability of the ground to absorb rainwater. This leads to a higher volume of surface runoff, putting pressure on drainage systems and increasing the risk of flooding and waterlogging.

What was the traditional approach to water drainage systems?

The traditional approach to water drainage systems aimed to expel water as quickly as possible, directing it into the nearest drainage or water body. This method often contributed to issues like flooding, ecosystem disruption, and reduced water availability.

What is eco-drainage and how does it differ from traditional drainage systems?

Eco-drainage (also known as ekodrainase) focuses on controlling excess surface water by promoting its natural absorption into the ground, rather than quickly draining it away. This approach is environmentally friendly and helps prevent flooding, groundwater depletion, and ecosystem damage.

What is a 'sumur resapan' and how does it contribute to eco-drainage?

A 'sumur resapan' is an infiltration well, a hole in the ground designed to collect rainwater and allow it to seep into the soil, replenishing groundwater. It plays a crucial role in eco-drainage by reducing surface runoff and mitigating flood risks.

What benefits does implementing eco-drainage systems provide?

Implementing eco-drainage systems helps reduce surface runoff, decrease flood risks, improve groundwater levels, prevent land subsidence, reduce soil erosion, and protect coastal areas from saltwater intrusion.

What is rainwater harvesting (Sph) and what are its uses?

Rainwater harvesting (Sph) involves collecting rainwater from roofs, paved surfaces, or other areas to be stored and used for daily activities like watering plants, washing, and other non-potable uses. It helps reduce reliance on municipal water systems and provides an alternative during dry periods.

How does rainwater harvesting contribute to environmental conservation?

Rainwater harvesting helps reduce surface runoff, which can prevent flooding and erosion. It also decreases the demand on municipal water supplies, offering an alternative water source and contributing to sustainable water use.

What is the relationship between eco-drainage systems and climate change adaptation?

Eco-drainage systems contribute to climate change adaptation by managing excess water more effectively, reducing flood risks, and improving groundwater recharge. These systems help communities become more resilient to extreme weather events and changing precipitation patterns.

Why is community education important for the implementation of eco-drainage systems?

Community education is essential for the successful implementation of eco-drainage systems because it raises awareness about the benefits and encourages the adoption of sustainable water management practices. Collaboration between researchers, practitioners, and local stakeholders is key to ensuring widespread adoption and long-term success.
