Drip Irrigation Case Study – Follow up

Following our case study Article and Video – Drip Irrigation in the City, we received expert response from a Ranchi, India based Civil Engineer, with almost 40 years’ experience.

Based on this discussion, and feedback, this week’s article outlines possible issues that may arise with use of this technology in Residential colonies.

In Case study 1 (original Case Study -Residence A), the Balcony A in question lies adjacent to a plumbing Shaft A, containing supply water pipes to the house. Thus, the plumber can easily provide a water connection (Source for the Drip Irrigation System) from this shaft to the balcony.

However, in Case Study 2 (Alternative Scenario – Residence B), the positioning of shafts is different. The Shaft B in the house (Residence B) is placed far from the Balcony. This makes it difficult to provide a water source for the Drip System.

The Shaft C, which offers a more direct route to Balcony B, contains water supply pipes belonging to another flat (Residence C). Thus, the plumber would be unable to draw a connection from this shaft.


Solution:

Such technology could be Integrated at earlier Design stages in future Residential constructions. Thus, shaft and water supply lines could be planned accordingly, for convenience to Residents and to save Water.


We look forward to more such expert opinions, feedback,
comments. These help us move towards further Sustainable Solutions, for our evolving Built and Urban Environments.

‘Drip Irrigation in the City’ | A Case Study

An Efficient technique largely used in Greenhouses and Agriculture, could be ‘Adapted’ to serve ‘Emerging’ City Needs – Assist Aging Populations and Address Water Shortages.
Looking at a City Case Study, Details, Pros and Cons.

This week we document Drip Irrigation used for balcony garden irrigation. The Case study is a 1000 sqft. flat dwelling, housing 2 aging persons. Having a large ground garden, while living in a metro city is a luxury most cannot afford. So, many people nurture beautiful balcony gardens. Often aging parents or grandparents may be living alone and looking after these spaces. They may or may not have access to domestic help for daily watering of plants. New developments are often also plagued with water shortages. Tiled balconies can become messy and slippery with pipe or bucket watering, thus posing a danger to aged people living alone.

We thus explore this technology, used in our case study, that may be able to address the above issues. It could remove unnecessary risk and make life a little more convenient for aged people.


The Nuts and Bolts

Looking at 3 main details

1) Origin – Tap, Tap Connector, Elbow Connector, Main Pipe

2) Route – Main Pipe, Elbow/ Tee/ Straight Connectors

3) Destination – Main Pipe, Feeder Pipe, Stake/Anchor to hold Feeder Pipes in the soil of pots, Drip Emitter

Some advanced kits also include automatic timers for scheduling the watering cycle.


Cost

The whole kit could cost between ₹ 300 to above ₹ 7000 (around $4 – $100 depending on company, number of plants)


Pros and Cons

The Pros and Cons are based on feedback for the technology by the owners. 


Note: The products utilized by the owners in the Case Study are by a company called CINAGRO™.  We are spreading information about the ‘adaptive’ use of this technology to solve important city issues. We however, are NOT endorsing the products/ company in question. You could search for Drip Irrigation Garden online. There are various companies that sell/ install such products.


Hope these details help you make decisions for your homes and the homes of other aging people with similar requirements.

Have you used a similar technology in your projects? Tell us about your experience. Did you face any other issues than the ones described above?

Do you think this ‘Adaptation’ can help address Emerging city needs?

Let us know!

Part 5/5: The Red System (Energy), Singapore

This is part of a series of posts based on scripts, written for class presentations during our Masters in Integrated Sustainable Design at National University of Singapore.
The class had to analyse various complex systems in Singapore, as a precursor to the Design problem in Studio. The systems included are – Red (energy), Blue (Water), Green I (Biodiversity), Green II (Food) and Grey (Public Space).
The following posts elaborate on the Red System.

Part 5/5: How can energy be restructured to improve self sufficiency and reduce emissions?

The 4 parts of the series till now outline the existing Energy system of Singapore – its timeline, characteristics, issues. We saw a Sankey diagram in Part 3/5 detailing existing flows and exchanges, while Part 4/5 elaborated on the System Structure at 3 scales.

This final part talks of an ‘After‘ Scenario where we propose a ‘Restructuring‘ to address issues and gaps – to improve self sufficiency and reduce emissions. Continue reading “Part 5/5: The Red System (Energy), Singapore”

Part 4/5: System Structure

Welcome to Part 4/5 of our series on the Energy System of Singapore. Part 1/5 established that the system has a gap at the neighborhood scale, that it is highly centralized and the largest demand sectors are Industrial and Commercial. Part 2/5 analysed the timeline of the system from the 1800s to present day, and looked on to the future – with a focus on important policies and events, and their corresponding effects.

Part 3/5: System Flows and Exchanges

Welcome to Part 3/5 of our series on the Energy System of Singapore. Part 1/5 established the objective and boundary condition of the system. It then identified the Elements, and Flows & Exchanges between them, to set relevant scales of study and understand critical functions. We found that the system has a gap at the neighborhood scale, it is highly centralized and the largest demand sectors are Industrial and Commercial. Part 2/5 went deeper into the analysis by looking at the timeline of the system from the 1800s to present day, and looking to the future. The timeline reflected important policies and events, and their corresponding effects using maps at Regional and Island scales.

Moving on from the above base, this post delves deeper into the System Flows and Exchanges. The Analysis is divided into 3 sections – Generation, Transmission, Distribution & Consumption.

Part 2/5: System in Time

Welcome to part 2/5 of our ongoing series, on the Energy system of Singapore. The last post established the objective of the system. We then started analysis by first establishing a boundary condition and later identifying the system’s Elements, and the Flows & Exchanges between them. This was done to set relevant scales of study and understand critical functions such as generation, transmission, consumption. We gathered that there is a global scale and 3 local scales for this system – Island, 10 km X 10 km and building. There is a gap at the neighborhood scale. We also found out that the system is highly centralized with high demand from various sectors, the largest being Industrial and Commercial.

Keeping this base work in mind, we move deeper into the analysis and understand the timeline of the system starting all the way from the 1800s to present day. We also look at future aims and targets to address present issues.

The following posts elaborate on the Red System.

Part 1/5: What are the Objective, Boundaries, Elements, Flows & Exchanges of the Red System in Singapore?

The ‘objective‘ is established keeping in mind short and long term goals. The short term concern would be to create a resilience to Supply – Demand Balance. For the long term, development needs to be Sustainable and the System should address Environmental Issues.

For the analysis we explore the Systems Thinking approach. For this, we first establish the ‘Boundary‘ conditions for the system. This helps identify Scales and to find Gaps. If the system is reliant on factors outside the country, then there would be a Global scale. Within Singapore, we assume 4 local scales – Island, 10 km X 10 km, Neighborhood and Building.

Next, we break the system into its constituent ‘Elements‘ to understand the ‘Flows & Exchanges‘ between them. This critical understanding helps us find flaws, shortcomings, and even opportunities at every stage. These can then be addressed or exploited to bring about improvements.
