Water Management Model

Project background

Executive summary

Bangalore’ in the process of becoming ‘World Class’ city by implementing the mega Infrastructure project involves land use change from agricultural rural areas in the periphery being converted to urban land uses. In the process, landscape surrounding the lake and the village appears to have transformed from a wetland-lake ecosystem which acted as a village commons to polluted sewage pool. The lakes in Bangalore region are now inadequately maintained, polluted with sewage and solid waste and with depleting water quality and quantity.

Aim of this research project is to conservation of Lakes and other water bodies In peri-urban areas in Bangalore Metropolitan Region in an ecologically viable and socially sensitive manner on cost -effective and economically viable technologies to enhance livelihood opportunities of various water users and promoting traditional water management practices in a sustainable manner.

This project involves

Identify the traditional management practices of various lakes users

Identify the various water users such as farmers, fishermen, dhobi, cattle owners, fodder collectors, women who use water for domestic purposes, who earn livelihood from the lakes and identify measures to sustain and increase their livelihood

To identify potential threats to these lake users and disturbances to lake eco-system

To propose appropriate measures for protection of lake users and lake territory and its watershed

To promote ecologically wise-methods to enhance the bio-diversity by usig a new process is used to treat waste water by using an innovative diatom algae nano-technology. The growth of diatom algae is very rapid in waste water and it absorb nutrients & CO2 , thus clean up the lake

 

Please provide a description of the project background and include answers to all of the following questions:

a) What is the demonstrated need for the project

b) How does the project support the national government’s policy and/or stated targets on sustainable access to safe water and improved sanitation in the country where the project is to take place

c) How does the project meet regulatory or other legal compliance requirements in the location(s) where it will be carried out

d) How does it set a high benchmark for innovation

Most of our rivers, lakes, ponds and other water bodies are highly. The recent Comptroller and Auditor General of India (CAG) Report of 2010, says that, the rivers and other water bodies are severely polluted. A CAG report on Bangalore says that- 100 million litres of untreated sewage is let into the rivers, lakes. In turn, this river water is used by farmers in downstream for growing crops and we eat such food grown by using this polluted water. CAG report blames Bangalore Water Supply and Sewerage Board ( BWSSB) in Bengaluru to take moral responsibility of handling sewage and to treat them before letting into river, lakes etc. But sewage treatment is very costly, sewage is spread out. So should we allow or rivers, lakes and other water bodies to be polluted??

Objective of this project – Polluted water is a serious health hazard and it is desirable to clean up rivers, lakes and all water bodies from the water borne organic wastes generated from the pollutants and sewage in an ecologically viable and socially sensitive manner by involving local community people in participatory planning process so that waste is converted to wealth. This uses an environmentally friendly technology and enhances livelihood opportunities by increasing the per capita income of various water users such as farmers, fishermen etc and promoting traditional water management practices in a sustainable manner.

Government agencies must involve traditional community-based users such as fodder collectors and fishermen etc, in planning process to bring in participatory planning. As per the provisions of the Karnataka Town and Country Planning (T&CP) Act, 1961, provides for public consultation in planning and implementation of any project.

No sewage or effluents should at all be let into the water bodies, and in any case they must be discharged after appropriate treatment in accordance with the Water (Prevention and Control of Pollution) Act, 1974

The Government-Bangalore Urban local body, Bangalore Water supply &sewerage board, Gram Panchayat have agreed to implement this new innovative solution for restoration of water bodies. They will make the investment as we have already demonstrated the technology for its cost effectiveness. It saves them more than 75% of the costs and thus Government is willing to take this project on large scale.

The innovation is that, it is a patented idea. It helps growth of diatom algae in any water – saline, fresh water, polluted water, sewage water etc & is used to clean and reuse the waste water. The growth of diatoms is very fast and happens within 5 minutes & continues till the nutrients lasts. Growing diatoms absorb CO2 & release O2 at micro plant level. The O2 helps aerobic bacteria breakdown organics into its constituents and thus cleans up the waste water. Suspended solids break down into nutrients, gases & sludge

Model for In-situ development of lake considering social, ecological, livelihood, traditional management practices of lake management

Assessment of morphology of lake

Review of historical , spatial, socio-economic dimensions of the lake and its users

Review of the existing status of lakes based on identity issues and challenges

Task identified for maintaining the traditional lake management practices, ecological and socio-economic functions of lake

Protect lake systems while developing new layouts, industries and infrastructure projects.

Local Rights to be recognised for better use of lakes- while lake restoration special provisions in the lake have to be made to protect those whose livelihoods depend on lakes. Any lake management plan has to integrate the interests of local communities

 

Participation of women, young people in lake management- Particularly, in rural and peri-urban areas where portable water supply is not adequate, women play the most vital role of obtaining the daily needs of potable water sully for their homes. Hence participation of women is very essential for lake management

Moving away from Civil Engineer’s model for lake restoration, but using social engineering method. The civil engineering model does desilting of the lake & then utilises this mud for in situ development of ringed-elevated-wide jogging tracks so as to cut costs involved in transporting mud elsewhere. This ringed-elevated-wide is unnecessary within lake area. Such desilting practice of this model leads to swift destruction of natural structure of the lake. All lakes in Bangalore have a pattern that, the deepest zone is close to the bund and the depth gradually increases towards the foreshore. Present design model indecisively deepens the lakes, frequently contributing to the collection of polluted waters resulting in extensive pollution of ground water aquifers.

Innovative Island Design

Live fencing of Lakes instead of stone wall or mesh fencing- If the lake is situated in dense urban areas, this method ‘live fencing’ is used. In this method, tree of specific species are planted all around the lake instead of fencing. This method will not restrict the entry of local community from entering, but it will help check encroachment on the lake bed. This would also save hundreds of crores of public money from needless construction of stone walls. This live fencing with specific species of trees would help build bio-diversity of lake & would also be a minor forest produce for local community.

As an alternative to the current practices of ringed elevated jogging tracks, a packed-mud or stone can be made all around the lake. This will be on the ground-level & it would not obstruct the water from the surrounding catchment area from entering the lake.

In the open lake area that spreads above this mud and stone walkway, around the perimeter of the lake, several select trees that are beneficial to birds, butterflies & other biota can be planted.

New process of Sewage treatment in a decentralised manner using a di-atom algae in a environmentally friendly and cost effective way. In water, growing algae has the capacity to consume nutrients and absorb CO2 and release oxygen by photosynthesis.Growth of diatom algae in any water – saline, fresh water, polluted water, sewage water etc is used to clean waste water and this is very fast & happens within 5 minutes. The growing diatoms absorb CO2 & release O2 at micro plant level. The O2 helps aerobic bacteria breakdown organics into its constituents and thus cleans up the waste water. The diatom algae produce food by photosynthesis & this becomes food for zooplankton which is eaten by fish.
