Republic of Serbia – Wastewater Management

• 60% of the population or 52% of all households are

connected to the sewer system • 431 Mm3/a municipal wastewater produced in 2013

70% evacuated 10% treated (2% tertiary treatment) 8 optimal operating WWTP

• Danube river is the final recipient 41% over direct discharge, the rest over its drainage basin

• Percentage of industrial wastewater: ~ 20% 4% treated

Ref:, SORSc,2013; GRS, 2011; GRS 2014; JCI, 2011

Summary of Main Challenges

• No reliable data • Institutional capacity not optimum • Where applied, treatment technology in use is outdated • Insufficient public awareness of sustainable water management

• Average drinking water consumption can go up to 350 l/(cap*day) • Water loss rate 30-80% • Insufficient water tariff structure, approx. 0,41 EUR/m3 • Scarce billing (50% of the generated wastewater is actually paid by the

consumers) • On the household level, only 0,1% of the available financial sources goes for

wastewater utilities

Biomass Potentials in Serbia

Agricultural Sector • 64% of the territory (5 Mio.ha) is

covered by the agricultural land 65% are arable (0,7 ha/capita) • One of the main contributor of the

Serbian GDP 17% • 58% crop fields & 42% livestock

production

Waste Management Sector • MSW: 2,6 Mio.t/a 50% OMSW • Ca. 70% MSW is collected • 164 Official landfill sites • OMSW at the moment not used for

energy production

Main Drivers of Action

• The main priority of the Republic of Serbia is becoming an

EU member state - since January 2014 Serbia is recognised as a candidate for membership

• The adoption of the EU Acquis • Wastewater management sector €3.3 Billion (GRS, 2011) • Waste management sector €2.8 Billion (GRS, 2011)

“How to generate a good quality effluent?”

“How to achieve good effluent quality while minimising energy demand for treatment and generating regional added value ?”

Wastewater as Energy Carrier

Source: Adopted from Cornel et al. 2011

Reclaimable at the source

Can be transporrted without losses

Potential Energy Epot= m*g*h 122 l/C*d, h=50m 6,1 kWh/(C*a)

Thermal Energy Ethm= cp*∆T*m 40 l/C*d, ∆T=15C 254 kWh/(C*a)

Chemical Energy CH4+2O2 = CO2 + 2H2O

COD = 120 g/C*d; 1 kg COD=350l CH4=3,48 kWh COD (1 mol CH4) = 64 g V = 22,4 l/mol (S.R.T)

152 kWh/(C*a)

Total Energy out of Wastewater 412 kWh/(C*a)

Energy content of wastewater as potential, thermal and chemically bounded energy

Scenarios Postulation

• Scenario 1 - wastewater is evacuated to one central WWTP • Scenario 2 - one central WWTP and additional decentralised

units For the Scenarios development following was considered:

• Stagnant population number, but increase in sewer network coverage to 95% in the municipality of Stara Pazova and to 65% in the municipality of Indjija (as foreseen by the responsible PUCs)

• Intensified industrial production.
