Patna diary: Analysing its Urban systems

Patna diary: Analysing its Urban systems

Every city depends upon certain core systems to run smoothly and efficiently. Water, sewerage, solid waste management and drainage; without these urban systems, a city would simply collapse. And on these core systems are build the secondary systems that make a city living worthwhile; like public health and sanitation.

What is the status of these urban systems in the city of Patna? Has climate change added to their vulnerability? A quick look at the existing conditions in the capital of Bihar.

Waste galore!

The city generates about 1000 metric tonnes of solid waste per day, but only has the capacity to dispose 65 percent of the total generated solid waste. Which means that an equivalent of  more than 30 trucks of garbage are being thrown haphazardly, every single day on the streets of Patna.

The 870 waste collection centres inside the city are acutely insufficient for this populous city of 16.8 lakh people. And so, people simply chuck out all their garbage at any convenient dumping place, more so in open, unused land. Increase in temperature aids its decomposition, and this turns into a messy, soggy spot where the mosquitoes happily breed in.  And when it rains, areas get waterlogged, polluting the close by water bodies and the groundwater below.

Waste that is collected through tractors or other open vehicles, spills over into the roads during transportation. The roads remain dirty, smelly and unhygienic. Most of the waste is dumped on to a waste site, about 22 km away from the city, without any form of segregation or treatment. Families that live near this landfill have to deal with the stench, disease conducive environment that takes a toll on their health.

Drained Out…

The city has 460 km of pucca drain, 340 km of kuccha drain and 1200 km of underground drain, which prove inadequate, with the city regularly in the throes of waterlogging.  The eastern zone, the old city area is riddled with narrow lanes, a major hindrance in setting up of an effective drainage system. The western zone is dotted with pumping stations which the municipal corporation has installed as a counter measure against the acute waterlogging faced on a regular basis. And many areas in the southern zone are still without any drainage facility whatsoever.

People dump their garbage and debris directly into the drains, which tends to block the flow of water in them, and the filth laden water, simply overflows onto the open land. In many places, the cleaning of the drains is not carried out regularly or the drains being old and decrepit are unable to handle the water content.  Many houses have been constructed above these drains, thus obstructing the path of the drained water. Waterlogging, is thus on the rise.

Sewerage

The city has its own underground sewerage system, four sewerage treatment plants and a 24 km long sewer pipeline. But, only 20 percent of the houses in the entire city are connected to the underground sewer and nearly 80 percent of the families use a septic tank and a cost effective toilet which pollutes the underground water. More importantly, the water supply line and the sewerage lines follow the same path. With the passage of time, wear and tear of the pipelines has occurred and water from the sewerage line enters the water supply line, thereby polluting it.

With limited public toilets, increased slum population with inadequate toilet facilities and the migrant population that comes to the city, the present sewerage situation is definitely inadequate.

Drinking water

Patna city depends upon groundwater for its drinking water provisions. 98 tube wells, 190 km pipeline, 30000 public stand posts and around 23000 public hand pumps are there in the city. Inspite of this, water reaches only 60 percent of the house; the bereft 40 percent makes do with shallow pumps.

Besides this, there are other problems too. The water pipelines leak at several places, an invitation to pollution and also causing a loss of nearly 40 percent of a precious resource. Many of the pipes criss-cross the existing roads, and are thus difficult to maintain and repair, affecting their water carrying capacity. Other places they choke and burst, and the drain water pollutes the drinking water in the area.

The quality of the drinking water too is questionable. Every day Patna belches out 224 MLD of sewage, of which half enters the river Ganges, while the other half is left to pollute the groundwater. There are four sewage treatment plants with a capacity of 150 MLD, but only 50 MLD reaches them. Sanitation

Patna ranked at a lowly 746, in a cleanliness survey conducted by the Government of India in 2016. Of the total 1796.23 acres of unplanned land, nearly 12 percent is encroached with haphazard waste management and sewerage services. More than 436 slums in the city face problems of cleanliness facilities, water drainage system and solid waste disposal issues, and more than three lakh people depend on shared public toilets for their primary sanitation need, many of which are in a broken, dilapidated condition.

Presently, there are 105 public toilet complexes connected to the sewerage system, and only 15-20 per cent of the sewage system is covered. Even though sewage is disposed through septic tanks and soak pits in the city, it flows directly from the septic tanks into the open drains and into the rivers during monsoons.

Homes

An expanding Patna is trying to fit in the increased population and regular flow of migrants into the city, and the result is unplanned urbanization and even sabotaging of the flood plain areas and existing wetlands to make place for the increasing populace. Dense settlements, tight streets and cramped, badly ventilated homes are taking a toll on the health of the children. Safety in such packed environment is short-charged more so for the young adolescent girls here.

There are 107 slums in the city and nearly one fourth of the population resides here, most of which are ramshackle places, right next to the drains. Shivpuri, one of the sums is located on the railway land, and has no hand pump for water, and obviously no toilet too. There is no system for waste collection, which simply piles up near the houses here. When the drains are cleaned the muck from the drain is simply dumped in front of the houses, without any thought of health or hygiene.

Ecosystems loss

In the march to urbanization, Patna is fast losing its green cover and existing water bodies. Unchecked dumping of garbage or raw sewage in these water bodies is slowly killing them. As per Master Plan 2030, only one percent of the area is occupied by waterbodies. In Phulwari Sharif, located near the AIIMS in Patna, a 17 acres pond has reduced to mere 3-4 acres. Not only has the size been cut down drastically, but new colonies have sprung up all around this diminishing pond, and the sewage from here is directly flowing into this lost body.

Agricultural land around the city has been taken over by brick kilns. The biodiversity of the peri-urban areas is being affected and the livelihood of the marginal farmers is at stake here.

Patna diary: A city under stress

Patna diary: A city under stress

Patna, the capital of Bihar, is an expanding city, both in terms of area and population. Climate change impacts are being felt across this metropolis and it is the more vulnerable, the marginalised, who find it increasingly difficult to cope and respond to such climate change induced extreme events. The city faces the challenges of urban flooding, unplanned infrastructure development and seems to be already on the way to be stressed out.

The water effect

Waterlogging is already rampant, and its reach has increased vastly with more regions experiencing it. Destruction of water bodies and building over open spaces have reduced the water holding capacity of the city, and turned the city even more fragile.  And of course, it is the poor and the marginalised who face the brunt of this. They are the ones who usually live in these at risk areas, and their homes and lives are both disrupted when such events occur. Water easily enters their low-lying houses, especially in the slum areas. The men and women lose out on their daily wages, their source of income, as they run around trying to salvage their homes and belongings. For the children, it means missing out on school, even as the roads to these areas gets inundated. In other case, the schools themselves may shut down due to the heavy downpour, cutting short a child’s educational journey.

Patna not only has insufficient drains, but also an inadequate sewage system. Open drains dot the city and there is an absence of an effective waste management system. And so in the waterlogging prone areas, when heavy rains lash, the drains engorged with the heavy load, simply spill out all that right onto the streets.  There this contaminated water lies for days, seeping into the ground and contaminating the groundwater. For the mosquitoes, a convenient breeding ground is ready, but a major health issue for the inhabitants.

Rising heat

More heat and more cold, it is getting colder and warmer, both the extreme temperatures are on the rise. Use of air conditioners is on the rise as is the incidents of heat strokes. Homes are poorly ventilated dependent upon power based on fossil fuels; green areas are vanishing, land becoming concretised and water bodies disappearing fast.  All this is adding to the heat island effect in the city. For more days now, the duration of temperature regime that between 10-20 0C, a range conducive to mosquito breeding, has increased. Obviously, water-borne diseases too are on the rise.

Periods of extreme humidity have increased, and the interplay of increased temperature and humidity has created a more problematic and unhealthy environment.

Not my concern

A large floating population moves into the city every single day in search of daily wages. A feeling of responsibility and lack of ownership by the people adds to the vulnerability factor in the city. Encroachments, loss of blue-green spaces, lack of enforcements of Master Plan, poor governance mechanisms and administration of basic services; All these exacerbate an already frail condition.

The stress and the shocks that the community face, more so the marginalised communities, are on an upward swing. Urban floods, waterlogging, sun stroke and a sudden increase in diseases; all these add to the stress of the people living in the city. A shortage of toilets can thus have both sanitation and health ramifications. All this spills over in the form of physical, mental or financial duress for the community.

Stressed out in the city

All these factors enhance the climate risks in the city, giving rise to umpteen shocks and stresses that render people who are marginalized and live in the fragile settlements of the city, even more vulnerable. The impact is much more on the children, who are affected to a greater extent.

Patna diary: How a changing climate is making its presence felt

The climate is a-changing in Patna. For the last 30 years, rainfall pattern has shown a downward trend, and every passing year the city is experiencing lesser and lesser rain. Simultaneously, the number of days of very heavy rainfall has increased in the last twenty years. Winter season is warmer, even though both the minimum and maximum temperatures have risen significantly. Summer is longer, and has extended towards March. And there are more days with a temperature above 400 C, with the years 2005, 2010, 2012 and 2014 recording the highest number of days above 400 C temperature.

And that is today.

Looking ahead at the future projected changes expected in both temperature and rainfall across Patna, and a grim picture emerges. By 2050, a nearly 20C rise is expected in both the minimum and maximum temperatures. There may be upto a four times increase in extreme rainfall events and the city will have to brace up for more hot days, warm nights and heavier monsoons.

Add to this risk induced climate cocktail, the unplanned infrastructure booming in the city, and the vulnerability rises further. As it is the city Patna is already hazard-prone, what with being nestled in a low slope gradient, lying in a saucer shaped topography, close vicinity to three rivers and with a high groundwater table. A 60 mm rainfall in 24 hours and the city in its present state is unable to cope with it even today.  Imagine the city in the future, what havoc this climate change and unchecked urbanisation will bring forth?

And the children, more so those who live in impoverished conditions, the urban poor, will be affected the most. Mosquitoes breed and flourish in this conducive environment created by increased humidity content in the air and rising mean temperature. Rampant waterlogging, unhygienic sanitation and congested living areas will only make things worse. With more vector- borne diseases on the rise, there can only be more ill health for the young.

Erratic rain patterns affect the food growing capability of land, especially for the small and marginal farmers in the peri-urban areas of the city. Agricultural fields gobbled up by the fast paced urbanisation, directly impact both the food production and diversity in the area. Needless to say, the children health will be affected.

The total number of children in the range of 0-6 years in Patna city is 203,041 of which 5 per cent live in the slum areas (Census of India, 2011). A child’s immune system is underdeveloped; they are at a far greater risk to disease, ill health and stress. And with climate change upsetting an already precarious balance, children are compelled to face difficulties in accessing education, may develop psychological stress and witness nutritional challenges, even as their individual growth and development is under threat.
