Patan Dhoka

Nestled right at the historic Patandhoka Gate- a prominent gateway to the UNESCO World Heritage site of Patan Durbar Square- this sanitation hub offers state-of-the-art, safe, and clean public toilet services to both national and international vistors. Bridging rich historical heritage with modern urban convenience, the facility is strategically located to serve the heavy foot traffic generated by the adjacent bus stand and nearby academic institutions. By providing reliable, high-standard sanitation to commuters, students, and tourists, this project ensures a comfortable, hygienic, and welcoming experience for everyone exploring the vibrant Patan community.

Key Features of Hub

 

1.     Neo Infrastructure

This Hub has two male cubicles for defecation and 4 units of the urinal for the male. One wheelchair-accessible cubicle for disabled users (it's free). The female block is comprised of 3 cubicles. The cubicles and urinals are equipped with a sensor-based auto flush system to maintain cleanliness after each use. The hub also consists of the sensor light and turbo ventilation fan for fresh air circulation. The handwash stations are also sensor-based supported by the liquid soap auto dispenser, sensor-based hand drier to promote a touchless handwashing experience and mitigate the contamination of germs like Covid 19. Signage in two languages, English and Nepali is present in the hub for the knowledge of these neo infrastructure to the hub users.

 

2.     Gender Friendly Public Toilet

The hub provides a gender-friendly environment to reduce the problem that women and girls are facing. Women feel difficult to use the public toilet since there are no light and water facilities at the public toilet. There are also cases of molestation in the dark public toilet and hence they feel insecure to visit the public toilet even they need it badly. But this public toilet is spacious with abundant light which makes the women feel comfortable and secure using the public toilet. Menstrual hygiene facilities like pad vending machines are placed where they can easily get sanitary pads inside the public toilet at a subsidized cost and the safety pad disposal machines are available. Users need not hide the pads above the doors or windows as there is a dustbin and also the pad vending machine. It also has hooks systems in the doors of a female toilet to hang their bags which has increased the safety among the girls. There is also a diaper changing area for the babies and also the breast-feeding station in the female compartment.

 

3.     Environment-Friendly Systems:

 

a.         Rainwater Harvesting System: Rainwater is the purest form of water. But the proper utilization of rainwater is very little. The hub consists of rainwater harvesting system for the better utilization of the water at the hub. The hub consists of a 600 sq ft catchment area for rainwater collection with 12000 liters of the storage tank. The rooftop rainwater is collected through the sky water filter that removes the debris and works as a first flush.

 

c.         Biogas Digestor: Fecal waste management is a major problem in the cities like Kathmandu Valley. Most of the septic tanks are connected to the river system and those which are not connected are collected by tankers and then finally disposed to the water systems. But the Aerosan Hub has developed a bio gas digestor of 10 cubic meters.
