STI WORK FOR SDG WALK THE SANITATION TALK

• Did not meet the MDG

• What is the current status?

• 2,400 Million w/o access to safe sanitation

• Yet WHO states that Return on Investment is excellent:

1 € gives returns of at least 7 €

CURRENT SANITATION SCENARIO

014

• Governments building toilets and these are not being

used ..... or are used

• SDG 6 Financing • Goal 6 – supporting many other SDGs

• Average ODA sanitation costs of € 2.4/person (own data) or € 12 per

household

• € 5,760 Million ODA required

• Average costs sanitation system € 150;

• Household size is 5;

• Sanitation construction € 72,000 Million needed. This can be largely met

by money markets

• What can STI do in this context ?

SCIENCE

Limited scientific research considering .....

Social science: why are people not using sanitation

Technical: limited (treatment processes)

017

• CENTRALISED SYSTEMS • Households connected to a sewer line leading to central treatment plant,

some innovations in treatment technology (struvite, energy recovery, etc);

very few new technologies in water using sewer systems

• DECENTRALISED SYSTEMS

• Septic tanks, pits etc.; few innovations (UDDT, biogas, re-invent the toilet)

• Treatment of faecal sludge has been largely ignored

Most of € 72,000 Million market is in decentralised systems for the following

reasons:

1) Central sewer systems are waterborne – water scarcity

2) Very high capital expenditure, disruptive in construction

3) Reuse difficult

4) Usually excluding poor areas

TECHNOLOGY

018

• Starts with realisation that old approaches do not scale

• CLTS (answer to why people are not using sanitation)• Community based awareness generation and demand for sanitation

• PPPs

• International public private partnerships in sanitation

RESULTSConversion of human waste into saleable products works best if mixed with other waste

Pilot business: pay-per-use toilet, organic

waste, biogas and charcoal making

Household toilet linked biogas units mixing

cowdung with toilet waste; > 750 units

installed

Pilot businesses: Composting mix organic

waste and human waste (vermi & windrow)

• Financial inclusion

• Technical & business development

• Behavioural change

• Integrated soil fertility management

• Behavioural change

• Financial inclusion

• Capacity development

• More use of local inputs

• Partial replacement fertiliser

• Science: (1) Behavioural change / willingness to reuse

including research supporting corresponding policy changes;

(2) Bacterial research / nano-technology possible game

changers (not known yet)

• Technology: Transport, drying, treatment, conversion of

human waste

• Innovation: Innovative financing: (1) new business in reuse

are still in pilot phase; (2) local leveraging ODA funding
