AEROSAN HUB_BUDDHAPARK

Key Features of Hub

1.     Neo Infrastructure

This Hub has two male cubicles for defecation and 5 units of the urinal for the male. One wheelchair-accessible cubicle for disabled users (it's free). The female block is comprised of 2 cubicles. The cubicles and urinals are equipped with a sensor-based auto flush system to maintain cleanliness after each use. The water in the flush comes from wastewater recycling. 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. All the cubicles are cross-ventilated. The cubicles have an award-winning uniquely designed Squatease Pan that was helpful in a comfortable squatting experience during defecation and further promotes toilet training. All the cubicles have hooks to hang the user's coat, bag, and purse.

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 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 a 612 sq ft catchment area for rainwater collection with 12000 liters of the storage tank. Annually 783,360 liters of rainwater is harvested. The rooftop rainwater is collected through the sky water filter that removes the debris and works as a first flush.

b.         Wastewater Treatment System: The hub utilizes the treated wastewater from the wash basin to flush the toilet. The design capacity of the wastewater treatment system is 1000 liters per day with a storage tank of 1200 liters. The wastewater treatment system is based on natural filtration by aerobic settling tanks and the reed bed. In a year around 3 lakh, 65 thousand liters of freshwater can be conserved utilizing the treated wastewater in the flush. This stops the wastewater from going into the natural river system contributing to the reduction of pollution of the river system and groundwater sources.

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 meter capacity and is generating biogas (methane) that is being used for cooking in its café. Bottom of Form
