Sustainable technologies emphasizes two things, that a system be a right fit for the community and of a high enough quality to last long-term. It is wise to strengthen the capacity of key stakeholders in a project, to make informed technology choices; and strengthen the production, construction and maintenance capacities of local providers as to be capable to respond to demands, opportunities and ideas from consumers and investors.
<font size="3">Technologies should be locally appropriate and context-specific, affordable, durable and demand-driven.</font>
There is a twofold approach:
'''1. Adapt the WASH technologies to the context where they are being used'''
*Preference for the use of locally made/available designs and materials
*The technology should not exceed the levels of complexity that match the expertise levels of people involved (users, mechanics, implementers)
*Use of options that are already available on the market, supply chains and service chains in place; and replicable
*Adhere to local rules, regulations, standards
*The technology should be in compliance with the need
*The selected technology should be affordable
'''2. Adapt the context to the technologies needed to deliver the WASH services'''
*Influence policy to include the technologies in use in local standards and regulations
*Involve local entrepreneurs in the establishment of the wash service
*Train local stakeholders (technical sustainability)
*Introduce sustainable means of financing of WASH in investments and O&M
*Introduce appropriate revenue systems
