STP water, or Sewage Treatment Plant water, is primarily intended for irrigation purposes in urban green spaces.
Recommended Uses of STP Water
According to the provided reference, STP water should be used for irrigation in urban green areas. This reclaimed water is a valuable resource for maintaining parks, gardens, and other green landscapes within cities.
Application Methods
There are specific ways recommended for applying STP water for irrigation:
- Flood Irrigation: This method involves flooding the area with water. It's mentioned that gardeners often prefer this method.
- Pressurized Irrigation System: This includes methods like drip irrigation, sprinklers, etc., which use pressure to distribute water more efficiently.
The reference notes that STP water should be used for irrigation in urban green areas by means of Flood Irrigation or by a pressurized irrigation system.
Practical Considerations & Gardener Observations
It has been observed that gardeners are hesitant of using STP water for spraying. Instead, they just do flood irrigation, which results in over-irrigation. This highlights a common practice that, while simple, can be inefficient and wasteful compared to more controlled methods like pressurized systems.
Using appropriate application methods helps conserve water, prevents waterlogging, and ensures plants receive the right amount of hydration. While flood irrigation is an option, pressurized systems generally offer better control and efficiency, mitigating the risk of over-irrigation noted with flood methods.
Here's a summary of the methods mentioned:
| Method | Description | Common Practice (Observed) | Potential Issue (Observed) |
|---|---|---|---|
| Flood Irrigation | Flooding the area with water | Preferred | Over-irrigation |
| Pressurized System | Using pressure (e.g., sprinklers, drip) | Less preferred for spraying | N/A |
In summary, the primary use for STP water is irrigation in urban green areas, utilizing either flood irrigation or a pressurized system, keeping in mind the tendency towards flood irrigation and its potential for leading to over-irrigation.
