Lucknow received the first heavy downpour of this year’s
monsoon on Monday 30th July. Just little over 100 mm of rainfall in 24 hours
wrecked havoc in the city! The railing over the Gomti riverfront over Kukrail
drain (it is actually a river – tributary of Gomti) broke due to excessive
flows of water. The low lying areas experienced up to the neck flooding with
their drawing rooms converted into a temporary swimming pool – only with filthy
and smelly water.
Several colonies like Lalplace, Gomti Nagar, Sector 8 and
Sector 14 of Indira Nagar, Model House, Mahanagar, Nishatganj, Aliganj,
Lalbagh, Aashyiana witnessed waterlogging and flooding. The road from
Engineering College crossing to Jankipuram Extension was under two-feet water.
Roads caved in several foot, developed cracks and were converted into cesspools
exposing the use of substandard materials and poor engineering. Many cars were
stuck midway on roads in areas like Aashiyana, Alambagh, Daliganj, Lalbagh and Jankipuram
due to severe water logging.
Haider Canal : Victim of Encroachment :
The three major drainage of Lucknow are Gomti River, Kukrail
River and Haider Canal – all of them are under great development onslaught.
While the floodplains of Gomti were encroached and huge diaphragm walls were erected reducing
the water carrying capacity of the river. Yesterday even the water was spilling
over the wall, indicating how vulnerable are the areas across the river. Haider
canal was actually a link canal, the most
ambitious project of Ghaziuddin Haider which was excavated to connect the river
Ganga in Kanpur with the river Gomti in Lucknow. The canal was constructed
across the heart of the city, but later had to be abandoned due to defective
slope, beating the purpose for which it was intended. However, it became a
major arterial drain of Lucknow running through several settlements and falling
into Gomti River.
Over the years, several colonies came up and they connected
their drains to this canal emptying their sewage and solid wastes into it.
Britishers were so thrilled with this canal that they shifted cantonment to
this area from Madiyaon – the earlier settlements in the north of Lucknow, and
Charbagh railway station also came up. Now the Haider canal lost its glory due
to its stinking water, slums infested banksides and several unauthorized
buildings right over it. Even a flyover choked a major portion of this canal
along the back of Mall Avenue before the
Raj Bhawan. Due to loss of carrying
capacity and encroachment it no longer drains sufficient water leading to
waterlogging. There are two underground pipes at Charbagh, one of which is
connected to Haider Canal. It takes the rainwater to Gomti River. However, the
pipeline is chocked and the canal is ailing, resulting in waterlogging at
Charbagh. The outfall of the canal was further tapped during the construction
of Ambedkar Park, thus a major portion of the canal was lost to a concrete
park. As if this was not enough, during
the construction of riverfront, massive diaphragm walls on both the sides of
the river promised tapping of the canal and drains to an underground
interceptor drain, whose design hasalready been proved wrong. The flooding will
become a perennial problem in days to come – thanks to our planners! In a drive
to beautify the riverbank, we stole the very land where excessive water used to
recharge our groundwater and save our colonies from flooding. These mistakes
will always make the city flooded during heavy rainfall.
Kukrail Drain : Dying tributary of Gomti :
Another blunder was closing the mouth of Kukrail drain and
converting it into a filthy nala. Once it said to be a major natural drainage system and lifeline for Gomti river, also it used to drain a major portion of Lucknow
right up to Jankipuram having a length of about 24 kilometers and covering
several colonies. After the plan to connect it to Bharwara STP through pumping
station opposite Bhainsakund and pumping water through heavy pumps, the natural
drainage was severely affected. Most of
the time, one or the other pump remains dysfunctional and takes months to get
repaired.
It's high time to restore these natural drains :
Year after year we encroached upon ponds, lakes, taals and
jheels of Lucknow that numbered around 1200 five decades back. Now hardly three
hundred of them exist bearing heavy trauma of urban wastes. They used to store
water and were excellent natural draining systems – storing water and
recharging groundwater at the same time.
Now we get flooded during rains, and our aquifers go down during summer.
The solution lies in restoring these water bodies and restoring our natural
drains and canals. The basic idea behind restoring these natural bodies lies in proper rehabilitation. The municipal corporation needs to remove all unauthorized structures on drains with regular cleaning to improve their natural flow capacity and avoid silting. Rainwater harvesting tactics can also be used for the better recharge in Ground water table.
