PUNE: The Pimpri Chinchwad Municipal Corporation (PCMC) has decided to sell treated water from its sewage treatment plants to other organizations for non-potable use.
Sanjay Kulkarni, executive engineer of environment department in the civic body, said, "It is for the first time that the civic body will sell the treated water to other organizations instead of utilizing it for watering civic gardens or releasing it into the river. PCMC will provide 10 million litre per day (MLD) treated sewage water to College of Military Engineering (CME) at Dapodi at no-profit no-loss basis, at the rate of around Rs 3,000 to Rs 4,000 per MLD."
He said the CME will utilize this water for filling up the rowing channel in their premises which is used for practicing boating skills. The civic body had signed an agreement with a German company around four years back for selling the treated water from the sewage treatment plants at Kasarwadi to industries for non-potable use. However, this project failed to take off due to poor response from the industries.
There are three treatment plants at Kasarwadi where around 74 to 80 MLD sewage is treated on a daily basis. The budgetary estimate for the work is Rs 2.48 crore. CME, through a letter on July 25, has conveyed its readiness to deposit the amount needed for this work and also pay the monthly maintenance charges. They have also demanded that the work be completed soon.
According to the proposal, to be tabled before the civic committees, there was no budgetary provision for this work in the annual budget of 2013-14. But, as the CME has agreed to pay the estimated expenditure, the civic body can carry on with the implementation of the project. The environment department has sought administrative approval for the work.
"CME wants the work to be completed before the start of summer season. However, the civic body will have to invite bids to allot the contract which will require around two months. It will also take around six to eight months to complete the work after the contract is allotted", said Kulkarni.

BWSSB to generate power using sewage water

Deccan Herald 24.08.2013 BWSSB to generate power using sewage water
For the first time in the State, sewage water
will be used for power generation at the Koramangala and Chalaghatta
valley in the City.
The ambitious project taken up by
the Bangalore Water Supply and Sewerage Board (BWSSB) is expected to
generate 1.05 kilo watt (kW) of power that will be used to run the 60
mld (million litres of water per day) sewage treatment plant (STP) at
the same location.
The project taken up under the Japan
International Cooperation Agency (JICA) at a cost of Rs 222 crores,
including operation and maintenance, is expected to be ready by June
2015.
Using unique technology, the activated sludge process will be generating power by the methane gas generated by sewage.
Though the STP will be a secondary treatment plant,
the technology will include Biological Nutrient Removal (BNR), a process
where nitrogen and phosphorus is removed from the waste water before it
is discharged.
According to a BWSSB official, the BNR is a
good enough for all non-potable purposes and the Board intends to supply
the treated water to the near by industries in future.
The STP
technology will also have the provisions of treating the water at
tertiary level in case the water is required for further use, the
official added.
New pipelines
The sewage
for the proposed STP is expected to be drawn from Sarakki (20 mld) and
Agaram (60 mld) where the pipelines will be integrated with the
Karnataka Municipal Reforms Project (KMRP) where in the sanitary
pipelines are being laid for the first time at many locations.
Waste
water from nearly 40,000 houses on Bannerghatta Road will be directed
to Sarakki Intermediate Sewerage Pumping Stations (ISPS) from where the
water will be pumped through 700 mm dia pipeline for nearly three
kilometers. Later, with the existing KMRP 2000 mm dia pipeline running
four kilometers will reach Agaram.
From Agaram ISPS, 60 mld will
be sent to Koramangala and Chalaghatta (K&C) valley and another 60
mld to the proposed STP at Bellandur Amanikere passing through 5.3 kms.
The
BWSSB will have to lay fresh 1000 mm diameter pipelines in the Defence
property near intermediate ring road for nearly three kilometers from
Agaram ISPS to K&C valley.
The BWSSB had pursued to generate
power through sewage water in 1990s, but they were not able to succeed
as they did not have the technology to hold methane gas for generation
of power.
However, by 2000, sophisticated technology with
advance components in STP plants had enabled the Board to take up the
power generation project.
K&C valley already has 248 mld
capacity STP plant which is one of the biggest and treats one-third of
waste water generated in the City.
However, at present the STP
is treating just around 215 mld per day and treated water is being let
out to into the Bellandur Lake.
Mundamveli sewage plant awaits govt nod

The Times of India 22.08.2013 Mundamveli sewage plant awaits govt nod
KOCHI: The Kochi corporation is awaiting the nod from the empowered committee, headed by urban affairs minister Manajalamkuzhy Ali, to start work on the Rs 95-crore sewage treatment plant proposed at Mundamveli.
"The work of laying sewer lines will start after we get the nod. All procedures prior to awarding tenders have been completed. We expect to complete the tender for the project by next month," said corporation health standing committee chairman T K Asharaf.
The proposed plant will have a capacity to treat 100 million litres a day (MLD) of sewage. Once the project gets rolling, sewage from houses, shops and commercial establishments in Fort Kochi and Mattancherry will be sent to the plant through sewer lines.
For this, a 20km-long high density polyethylene (HDPE) pipeline has to be laid. "Besides five pumping stations, we have to construct sumps every 30 metres in the middle of roads. As per the schedule, the work can be completed in two years," said Kerala Sustainable Urban Development Project ( KSUDP) project manager Abdul Jaleel.
Earlier, the corporation's efforts to construct the plant at Mundamveli had faced a setback following objections raised by the Kerala Coastal Zone Management Authority (KCZMA) and pollution control board. Work was suspended after complaints that the project violated Coastal Regulation Zone (CRZ) norms.
"Now we have received clearances from KCZMA and PCB. Efforts are on to vacate the stay secured by a citizen against carrying out the work," Jaleel said.
As of now, the 4 MLD treatment plant at Elamkulam is the only sewage treatment plant under Kochi corporation limits. The plant, constructed over four decades ago, is also not functioning properly.
