DNA/PUNE/14th Mar. ‘09: The Ghole Road ward office of the Pune Municipal Corporation (PMC) has set a fuel-saving example. A bio-gas plant, which runs on the waste collected from hotels and restaurants located on the Fergusson College (FC) and Jungli Maharaj (JM) roads, has been set up on its premises.

The biogas plant is used by the employees of the ward office to make tea that is served to the staff and visitors. Initiated by the ward medical officer Dr Sanjeev Wavare, the biogas plant also helps the staff save money. “We no longer pay for chai. Instead we make it here,” said a ward official.

Wavare said the biogas plant can treat 15 kg of waste everyday. “The staff of the ward office collects the waste (left over food, vegetables) from the hotels and restaurants and then puts it straightaway in the funnel of the plant,” he said. An equal quantity of water is then added to the waste. “The output of 15 kg of waste is around 250 gm of biogas, which is sufficient for a family of five to prepare tea, breakfast and lunch,” said Wavare.

There are around 275 hotels and restaurants located on the FC and JM roads. “These hotels generate around 16 tonnes of waste every day,” he said, adding that the ward office has now been propagating others to set up biogas plants and use this waste to generate gas. “This initiative at the ward office was aimed at treating the waste at source,” he said.

On a daily basis, the ward office collects around 80 to 90 kg of hotel waste and with addition of vermiculture to the waste, manure is produced in eight days.  The design and specification of the biogas plant has been approved by the Bhabha Atomic Research Centre, Mumbai. “This is a small plant and the cost is just around Rs15,000,” he said.

After this successful venture, the ward office has also suggested the idea to city colleges. According to Wavare, the Shri Shivaji Preparatory Military School (SSPMS) has already set up a biogas plant with the help of the Pune Municipal Corporation (PMC). The cost of the one tonne capacity biogas plant is between Rs9 to Rs10 lakh, he said.

Similarly, the Symbiosis Institute on Senapati Bapat Road and Symbiosis Institute of Management at Vimannagar have set up biogas plants of one tonne each. The Dina Institute in Model Colony has set up a 50 kg biogas plant. “These institutes have large campuses and along with canteen/hotel wastes, they also generate biodegradable waste such as leaves and other waste material. This can produce quality manure,” he said.

A bio-gas plant of one tonne capacity can produce gas equivalent to nearly five domestic cylinders in a day. According to Wavare, there are around 37 biogas plants in the city.

Speaking to TOI, municipal commissioner Ashish Sharma said that a detailed project report on water recycling has already been prepared. This report will soon be submitted to the Union government so that the corporation can implement the project under the Jawaharlal Nehru National Urban Renewal Mission.

According to Sharma, the corporation is looking at providing 120 MLD treated sewage water for industrial use from its various sewage treatment plants including the one at Kasarwadi. “We will be able to provide water at competitive rates. The location of the STP at Kasarwadi is convenient for providing water in the industrial belt of Bhosari and Pimpri,” he said.

The PCMC is also looking at power generation from sewage treatment plants, though the plan is in the initial stage, Sharma said.

As part of the works to be completed under JNNURM, the PCMC has completed the work of construction of four sewage treatment plants at Pimpale Nilakh, Chinchwad, Ravet and Kasarwadi. At Kasarwadi, the corporation already has one plant of 40 MLD capacity which is functional. Another plant of the same capacity is being built there. The other STPs that are functional include Chinchwad (30 MLD), Pimpale Nilakh (20 MLD), and Chikhli (32 MLD). The PCMC proposes to start more STPs at Akurdi (30 MLD), Ravet (20 MLD), Chinchwad (30 MLD) and Charholi (21 MLD).

Incidentally, district guardian minister Ajit Pawar had asked the PCMC to undertake water recycling projects on a large scale. His suggestion had come at a function in May last year when he laid the foundation stone for the Rs 400-crore ambitious project of laying a direct pipeline from Pavana dam to Ravet to meet the water supply needs of the twin township. He had pointed out that the Pavana river, from where PCMC draws nearly 340 MLD water for drinking purposes, gets highly polluted from Chinchwad onwards, due to release of domestic and industrial effluents from the twin township.

Meanwhile, welcoming the increased allocation for JNNURM projects in the interim Union budget, Sharma said that the municipal corporation wants to focus on the Pavana river improvement project. Similarly, development of two temples along the Pavana river banks the Moraya Gosavi Samadhi temple in Chinchwadgaon and the Jhulelal temple in Pimpri, as heritage structures, is top priority. The PCMC also wants to start work on stormwater drainage and nullahs, he said.

Regarding works related to BRTS which are to be funded under JNNURM, Sharma said the PCMC has received sanction for four routes. The PCMC, he said, wants to complete the Nashik phata flyover on top priority. The work, which is funded under JNNURM, is estimated to incur an expenditure of over Rs 90 crore. The corporation has already floated tenders for the work, he added.
