God's own Country......Nature's own way (on floods in the city)

Nature (and mother earth)  is a miracle; it can tolerate exploitation to a great extent. It has it's own ways of balancing itself; but as is true with any other thing, there are limits. Flooding in Thiruvananthapuram city is one of the best examples of how nature (and system) responds when it's own ways of maintaining balance are challenged.

A brief history

We had an enviable system to drain waters off the city roads and to provide fresh water to city during the times of erstwhile royal rule.  The kochar (now not to be seen on a map), a channel/tributary from killiyar, brought in fresh water to the city . The Padmatheertham pond (which is luckily still there) had an excellent overflow control system, which was accomplished by the  pathrakkulam (now theerthapadamandapam). Flooding in Thampanoor region was controlled by manjalikkulam and (as learnt from a post in facebook by Sri Mohan Kumar) the nearby marsh too.  It is obvious that everything was there for a well defined purpose. How true is the saying "old is gold"!

The manjalikkulam was converted to a playground and the marsh to KSRTC garage (information courtesy: Mohan Kumar in facebook).  As stated by The Hindu : "The soil that was removed during the demolition of the hillock was used to fill the pond. Manjalikulam (or Vavanjalikulam) was then a decaying pond and breeding ground of mosquitoes and a headache for the residents nearby. During the effort that was started during the Gandhi Jayanthi (October 2) of 1975, 3,000 loads of sand and soil (mostly from Shanghumughom beach from the mandapam area, which, incidentally, left a hole on the beach for some time). Filling the pond was hailed by one and all. However, both the construction in farm land in 1919 and filling of the pond in 1975-77 today would have evoked protest due to evolved environmental awareness. It is to be suspected that the filling of this pond is very much a cause of flooding in Thampanoor area."

There were a number of other ponds too: "Indratheertham (Attakulam), Brihutheertham (Manacaud Sree Dharma Sastha temple pond), Agnitheertham (Agneeshwara temple pond), Varaha-theertham (Sree Varaham temple pond), Dakshina Ganga (Thekkanamkara canal), Agasthya -kundam (Mithranandapuram temple pond), Kanvatheertham (Chettikulam), Varuna theertham (Karippukoikkal pond), Rudratheertham (Chirakkulam), Somatheertham (Manjalikulam), Ramatheertham (Vaniyankulam), Ananthatheertham (Padmatheertham), Eshana theertham (old Nandavanam pond)" as per Ananthapuravarnanam (courtesy: a 12th-13th century work, cited by sharatsunderrajeev.blogspot.in), most of which by now have vanished. Thus a well visioned, well planned and well designed storm water drainage system plunged in to history. The famous quote attributed to Cherston by John F. Kennedy: “Don’t ever take a fence down until you know the reason why it was put up” was violated many times, in many ways here.

The canals and other ponds

Flood waters were carried by pazhavangadi thodu, kannammoola thodu and ulloor thodu (getting leaner and shallower day by day thanks to the sediments, both natural and contributed by humans), the thekkanamkara canal and the parvathy puthanar (once a navigable waterway, connected to lakes and finally varkala tunnel; now the largest sewage and solid waste carrier) and the network of small drains.

Gone are the days of the royal rule, now it is new democracy: "encroachment of the people, for the people and by the people!". The recent operation anantha discovered many buildings constructed over and in to existing drains. The famous, still working thekkanamkara canal passes under huge building complexes in the fort area, and that would always remain a roadblock in the development of storm water drainage system in the city. 

Blocked drains

In old days there were no sewerage lines as houses had septic tanks. Water happily flowed unobstructed through the roadside drains. But when the sewerage system was introduced, people started cutting across these drains to lay their sewage pipes and water lines in order to get connected with the street water supply/ sewer line. The result: dams across roadside drains. 

At places where houses located near the old storm water drainage system, residents found it convenient to simply open their drainage pipes in to these channels, and later into rivers too! If the water was not contaminated, many of those innocent kids would not have lost their lives or suffered later, when the school vans plunged in to parvathy puthanar (It is not to be forgotten that the dredging of sand from these channels had made them dangerous for navigation too and that made rescue operations even tougher). They made these channels their garbage bins. Although the government resorted to construction of fences, the people somehow found ways to put garbage in, even by throwing it over the fence. The fences started vanishing over time too.

Vanishing paddy fields

Paddy fields and marshes are getting converted to real estate and everyone is building compound walls abutting streets around these converted lands. Whenever they needed an access to the property they simply did fill the drains that passed alongside the property; why spend on slabs? No body would want water to enter or stay inside their premises, so they raised their ground, and covered the land with cement concrete. The outcome is obvious: water flowing in to and collecting on street, damaging the roads in no time. 

The ultimate result

Mahatma Gandhi had once said "The earth has enough for everyone's  need, but not enough for everyone's greed".  In their haste to improve their own life, humans have forgotten the tolerance of nature and the need of future generations too.  Nature has put a question: now that you have plugged all the outlets, where will all this rain water go?  The equation is simple: more open land converted to concrete surfaces+more compound walls+ more water and wastes +clogged drains + vanishing ponds+rain = floods.

A  few words on Operation "anantha"

The government is now surely doing a good job with as of now a ten crore package, as the flooding has at least reduced during the recent rains. But opposition from many encroaching persons have put difficulties before the team involved in the job (manjalikkulam issue) .  It is ironical to note that people won't afford to lose a play ground, but they are ready to wade/swim through water mixed with sewage during every rain! More disgusting thing is that the same people who cause these floods by their actions blame the authorities for having a defective drainage system. It was shocking to see a huge heap (almost one storey high) of waste and debris excavated from the drainage canal just outside the fort area. Hope it will open the eyes of people and make them hesitate before throwing the next piece of garbage in to these channels.

Another achievement of the operation: a better and wider culvert across drain on Attakulangara Eanchakkal by-pass, which would be a boon for water and road traffic alike.

But there is a debate going on the effectiveness of the operation. As per Deccan Chronicle:"According to reports, a full-fledged drainage network  runs beneath commercial complexes." There is an allegation that the operation was  waste of money and manpower.  "The government has spent around Rs 172 crore  to solve  the flooding at East Fort and Thampanoor in the past two decades. The demolition drive which is going on is avoidable. Without retrieving  Pathrakulam, it is pointless to spend crores. They should have focused on cleaning up the Kannamoola and Akkulam stretch which is extensively encroached and clogged” 

Deccan Chromicle continues: "A senior official associated with the drive said that eviction notices would be served after finalising the plan.  The archaeology department has identified widespread encroachment of significant heritage property.  ‘Pathrakulam’-once a pond - was encroached long back.  However,  ‘Operation Anantha’ has failed to evict the encroacher which is one of the main reasons for flooding at East Fort region". Further, the operation is not to be considered as an eviction drive, but recovery of drainage network, including thekkanamkara canal and ensuring proper flow in the system (names of persons have not been mentioned here, as allegations remain allegations unless proved).

With no good inlets and feeder drains, cleaning up the middle or outlet portions of a drainage canal alone would yield no satisfactory results and hence the recovery drive in the city is justified. While it is true that restoration of the old drainage system would not be complete without retrieving Pathrakkulam, interestingly there is no  report on overflow observed at Padmatheertham during the rains. As noted earlier, Pathrakkulam was meant for collecting and diverting the spill-over from Padmatheertham.

The Future

No matter whatever drainage systems the authorities would introduce they would be proved futile if a few things like the following are not done by public: 

1. stop encroaching the drains and canals, 

2. stop dumping wastes especially non biodegradable stuff and domestic sewage,

3. say no to plastic, or at least reduce, reuse and recycle, especially plastic,

4. switch over to no flooring or interlocking block flooring in the compound

5. implement rain water harvesting.

6. commercial establishments which had come up over the old thekkanamkara canal and associated drains need to take initiative to ensure smooth flow through the system.

7. remember during every action that our future generation would have to pay for our deeds (sustainable thinking).

These steps, coupled with repairs to the old system and introduction of new systems would surely hep in realising a flood-free city. Restoration of the old system would be an ultimate solution, but considering the vastness of the issue the immediate focus on draining of  flood waters is justifiable as a short term measure.

update: article on the restoration drive in mathrubhumi: link

Update: 22/07/2015: Just like any good initiative from people who wish to do something good for the state, this too is facing hurdles now, thanks to the thoughtless acts of a few officials and allegations of corruption. Hope the project would overcome all hurdles and realise the dream of a flood free city....lets hope the project would not lose direction  and continue endlessly groping in darkness as its name.....anantha. link


Update: 26/12/2015: Recent attempts to clean up parvathy puthanar has met with setbacks from humans as well as nature......it is hard to work against nature, but humans? When will we improve?

Fig: Article from mathrubhumi nagaram (25th december 2015) on how parvathy puthanar revival drive faces setbacks.

Bridges shall no longer be places to have a feel of natural beauty, if this trend of fencing continues. We have to fence around the human tendency to dump wastes and violate rules. If someone wants to dump wastes, he/she will do it: either through, under or over the fence, as had occurred in the case of pazhavangadi thodu... Do we need another chennai episode here to learn?
