→Cross subsidies/Differential tariff systems
Differential tariffs in sewered systems charging below cost to poor users and above cost to others
Good approach in relation to differences in income provided total system cost are recovered which at present is often not the case. Also, it is difficult to ensure that subsidies reach the poorest groups (http://web.mit.edu/urbanupgrading/waterandsanitation/funding/estab-price-policy.html ; http://www.sanicon.net/themes/intro.php3?theme=3). High potential for connecting more people but costly and may reduce interest for dry alternatives
