Potential Locations
• Total number of locations 2866
• Total PE value 12.2 million
• Market size €4.5 billion (based on localities)
• Market size €5.4 billion
(based on estimate Romanian Government)

Competitiveness
• Decentralized vs. Centralized
– Centralized WWTP ’s domain of large players
– Dutch Water Sector : SME, niche products
– Small scale WWTP ‘s < 25.000 PE
– Area max. 5 to 7 km
– Low population density, mountainous terrain
– Total solution

Competitiveness
• Niche market; Membrane Bioreactor (MBR)
– Relatively more expensive
– High effluent quality
– Compact
– Future proof
– Modular
– Standardisation / reduction prices membranes

Competitiveness
• Product Strategy
– Decentralized WTTP ‘s
– Niche market, MBR
– Address all problems from planning to
financing to operating
– Partnership, partners are complimentary
– Continuous local presence

Affordability
