Decks cleared for STP at Autonagar
MBBR technology to be used for construction of the plant
A first of its kind Sewerage Treatment Plant (STP) will
come up at Autonagar in the city shortly. The Vijayawada Municipal
Corporation (VMC) has cleared decks for construction of the STP with
Moving Bed Biofilm Reactor (MBBR) technology.
The STP
is estimated to cost Rs.10 crore and will cater to the needs of 90,000
people in and around Autonagar. The corporation will invite tenders
shortly for construction of the STP with a capacity of 10 MLD. The
proposed STP is one of the treatment plants taken up under the
Jawaharlal Nehru National Urban Renewal Mission (JNNURM) programme in
the city.
Unlike other STPs where anaerobic process
is involved, the MBBR uses aerobic process. Hitherto, the VMC had
constructed the STPs with Upflow Anaerobic Sludge Blanket (UASB)
technology. The new method makes it possible to attain good efficiency
results of disposal with low energy consumption and the process is used
for the removal of organic substances.
The biological
oxygen demand has to be less than 30 to meet the national standards.
These standards could be met with the MBBR technology. The STP is
cost-effective, efficient, environment friendly and will bring down
expenditure on the power and maintenance, according to officials.
The
VMC will construct four STPs and six sump-cum-pump houses under the
JNNURM programme in the city. The corporation has planned to construct
two STPs at Jakkampudi and another two at Ajithsingh Nagar. The VMC
constructed a 40 MLD STP at Ajitsingh Nagar replacing a 27 MLD STP
constructed decades ago.
Another two STPs, each with a
capacity of 20 MLD, have been taken up under the JNNURM. A 20 MLD STP
at Ramalingeswara Nagar has already been completed, while an STP at
Jakkampudi is nearing completion, and remaining are in different stages.
The works have come to a grinding halt ever since the government froze
the release of funds.
