Urban Environment Improvement Project
As part of the 12th Five Year Plan Government have approved the Urban Environment Improvement Project as a one time ACA during the financial year 2013-14 with an outlay of Rs. 1005 lakh.
During 2014-15, an amount of Rs. 800 lakh and Rs. 500 lakhs during 2015-16 is set apart for the project.
During 2016-17, an amount of Rs. 500 lakh is proposed in the budget.
Objectives of the project are:
1. Preserve and restore green and open spaces sustainably and thereby reduce carbon emission
2. Rejuvenate the urban ponds for managing water scarcity and keeping the aesthetic values including biodiversity conservation
3. Effective management of household organic waste by converting the waste into energy through biogas plants
4. Terrace Cultivation – Cultivate safe to eat vegetables utilizing household organic waste/ slurry from biogas plant as manure and manage house hold organic waste in urban households.
5. Promoting Rain Water Harvesting.
Project presently has:
2656 beneficiaries registered for the basic package
ie terrace cultivation with organic inputs and supported with timer fixed drip irrigation scheme,
1515 beneficiaries opting for bio gas plants,
395 beneficiaries opting for poultry,
220 beneficiaries opting for fishes in fiber glass tanks.
The benefits from the Project to the State are:
Out of 2656 beneficiaries 71% of the beneficiaries, that is 1885 number of households, were cultivating in the last severe summer season.
This is because of the steady supply of assured irrigation to the plants through the timer supported drip irrigation system.
Along with this there is substantial savings in the water that is used for irrigation. While a grow bag consumes nearly 4 litres of water during a summer day, it is limited to an average of 1.75 litres with timer supported drip irrigation. Hence for 1885 beneficiaries with 25 grow bags the savings in water amounts to 1,06,000 litres per day. With this water saved, another set of 60,500 grow bags with seedlings can be brought under timer controlled drip irrigation ie. Almost all the present beneficiaries can opt for an addition of 25 grow bags with seedlings on their terrace with an additional investment of less than three thousand rupees on growbags and drip system.
The beneficiaries are getting on an average 0.75 kg of vegetables of different varieties like tomato, ladies finger, amaranths, green chilly, cluster bean, cowpea, curry leaf, ginger etc per day from their terrace cultivation and this amounts to nearly 1.40 tones of organic vegetables per day. At an average Rs. 50.00 per 0.75 kg of vegetables produced from an household the city under UEIP generates organic vegetables at a total cost of Rs. 94,000.00 per day which amounts to nearly Rs. 3.25 crores worth of organic vegetables in a year.
The benefits from the Project to the State are:
WASTE TO ENERGY – BIO GAS
Domestic bio gas units ranging from 0.50m3 to 1.50m3 has been provided to 1515 nos of beneficiaries with a subsidy of 70%.
The Total waste processed in kg per day in these 1515 nos of bio gas plants is 9938 kg.
Hence the solid waste processed in these 1515 numbers of biogas plants (9.938 tonnes) is equivalent to one by ninth of the daily capacity of Vilappilsala ie 90 tones as reported by PCB.
In addition a bio gas plant generates gas suitable for cooking to the extent of an average 400 gm per day (300 gm to 500 gm).
Hence the cooking gas generated per year per biogas plant amounts to 146 kg (400 gm x 365 days) which is almost equivalent to 10 cylinders of LPG of 14.2 kg. At the nonsubsidized rate of Rs. 607.00 per 14.2 kg LPG cylinder at Trivandrum the savings for one biogas plant for one year is Rs. 6070.00 (Rs. 607.00 x 10 cylinders). Hence the savings for 1515 biogas plants per annum is Rs. 91,96,050.00 (Rs. 6070.00 x 1515 numbers of biogas plants).
Further the slurry generated from the plant is diluted and used as fertilizer for the plants.
RESTORATION OF PONDS
The 32 ponds, which are already completed, averaging a water spread of 1600 sq. m can attain an additional storage capacity of 61.44 MLD of water with an effective additional depth of 1.20 m after renovation. This results in substantial rise in ground water level of the nearby areas as well as a source of water for irrigation and drinking purpose.
The additional storage of 19.20 lakh litre per pond at an average expenditure of Rs. 15.00 lakh indicates the achievement of the additional storage at 78 paise per litre.
In addition to this the rearing of an average of 40 nos of fishes like grass carp, cutla, rohu, mrigal etc per cent in these ponds will be generating an average of 80 kg of fishes valued at Rs. 250.00 / kg thus generating a revenue of Rs. 20,000/- per cent.
Thus the revenue generated from 32 ponds measuring an average of 40 cents per pond will be Rs. 2,56,00,000.00.
219 beneficiaries have opted for fishes in fibre glass tanks and they are presently rearing 12 nos of Karimean or 25 nos of Gift thilapia.
The karimean will grow up to 500 gm in one year and will be fetching Rs. 3,600.00 per tank at the rate of Rs. 600.00 per kg.
At the same time gift thilapea will grow up to 800 gms in 6 months thus yielding 16,000.00 in a year at Rs. 400.00 / kg.
Hence with 69 beneficiaries opting for karimeen and the rest for gift thelapia, the total out from the 219 beneficiaries in a year is Rs. 22,52,000.00.
27 nos of beneficiaries have opted for ferro cement tanks of 5 m3 and above capacity.
15 nos of the fish variety Pangassius is reared per 1 m3 in this type of tank and this will grow up to 800 gms in one year and will fetch Rs. 250.00 kg.
Hence with 27 beneficiaries averaging 5 m3 capacity of tank will produce fish worth Rs. 4,05,000.00 per annum.
416 beneficiaries have opted for poultry with cage and 5 chicks.
Each chick will be producing eggs at the rate of one egg for 300 days in a year and hence the total output for a cage with 5 chicks is 1500 eggs is Rs. 7,500.oo per year at Rs. 5.00 Per egg. Hence with 416 beneficiaries the total output in a year will be Rs. 31,20,000.00.
There is a total accrual of indirect monetary benefit of Rs. 730.73 lakhs per year
Savings on water with which a possible addition of 25 grow bags with seedlings on the beneficiary’s terrace with an additional investment of less than three thousand rupees on growbags and drip system
Solid waste processed in the 1515 numbers of biogas plants (9.938 tonnes) is equivalent to one by ninth of the daily capacity of Vilappilsala ie 90 tones as reported by PCB,
Additional storage of 19.20 lakh litre per pond at an average expenditure of Rs. 15.00 lakh indicates the achievement of the additional storage at 78 paise per litre to the State.
