Re-use of Treated water in Varanasi-Bhagwanpur STP
1.0 MLD from Bhagwanpur STP though 9.8 MLD is available for reuse. Reduction in
farming land has resulted in lesser use of treated effluent. Around 4.0 Acre land is
being irrigated.

India – sewage generation
Currently, India has the capacity to treat approximately 37% of
its wastewater, or 22,963 million liters per day (MLD), against a
daily sewage generation of approximately 61,754 MLD according to
the report of the Central Pollution Control Board.

1. Waste water treatment and use in humid reason of developed countries ( N.America , N. Europe and Japan ) are motivated by stringent effluent discharge
regulations and public preference regarding environment quality.
2. In arid and semi arid areas of developed countries ( Western N America , Australiaand S. Europe) treated waste water is used primarily for irrigation because of
increasing competition for water between agriculture and other sectors.
3. In Developing countries use of waste water in agriculture is because:
a) it is the only water source available for irrigation through out the year
b) waste water irrigation reduces the need for purchasing fertilizer.
C) waste water irrigation involves less energy cost.
d) waste water enable farmers in peri-urban areas to produce vegetables.
World wide treated water use

Issues
1.Cholera epidemic in Chili in 1991 due to agriculture use of
untreated waste water
2. Jordan export market impact in 1991 as fruit and
vegetable irrigated with inadequately treated waste water.

Planning
Plan & Design Sewerage
Treatment Infrastructure
for next 50 years
Implementation Phase 1
Phase 1: Treat all untreated
sewage with only preliminary
& primary treatment
Implementation Phase 2
Treat all primary treated sewage with
secondary treatment biological technologies
to meet 10/10 standards such that treated
wastewater can be used for irrigation &
industrial applications
Implementation Phase 3
Treat secondary treated
wastewater to meet tertiary
treatment standards for industrial
and other non-potable uses
Plans should be developed for complete development. Since it is challenging to accurately forecast and visualize all scenarios for a 50 year period the on ground development should be split into multiple stages. Since planning is not a costly activity, it should be taken up for a period of at least 50 years (equivalent to expected life of most civil assets) but the implementation should be done in phases to achieve highest return on investment and in the most timely manner.
High cost-benefit ratio. About 50 to 60% pollution reduction can be
reduced by adopting only preliminary and primary treatment along
with anaerobic digestion (where possible). Benefits:
• removal of plastics, rags, suspended solids (about 50%) d associated
organic pollution
•Low energy & low O&M costs (which is a big challenge)
High cost and difficult to select appropriate technology as it is dependent on various factors eg. Removal of plastics, rags, suspended solids (about 50%) and associated organic pollution
Very high cost and difficult to select appropriate technology as it is dependent on various factorseg. Without reuse potential, upgrading to high quality treated water would essentially lead to discharging high value treated wastewater into potentially polluted water bodies
