Introduction to the WaterCompass
Origin and objective The decision-support Profile Intended users
Rationale for the WaterCompass Problem:
Low sustainability of implemented technologies Tool:
An interdisciplinary support tool for a broader and more objective (rational) technology selection process
Goal: More sustainable water methods in practice
Introduction to the WaterCompass
The WaterCompass profile Fast and reliable computer-aided
human decision-making Tool: decision-support, not -making Computerized pre-screening of
technologies Final selection by user Transparent & easy selection Multidisciplinary knowledge on
technologies Reliable source of technological
applicability
Water | Energy
Needs Assessments | Low-cost Product Design | Technical Training Supply Chain Design | Quality Control | Field Follow-up | Evaluation
Potential users and intended uses
Decision-makers in the water sector Allow identification of method group fitting a certain criterion Allow identification of a method group fitting a defined
project or area Project engineers and other stakeholders
Enable efficient multistakeholder processes by providing a common platform for discussion
Water management sutdents Educate on method characteristics and applicability

Description FIETS information ‘Relevance’ sentences External links
The information modulesHOUSEHOLD-LEVEL, SUCTION HANDPUMPS
DESCRIPTION
Cheap water lifting option for maximum 100 people. For areas with low groundwater tables (<7m). Easy in maintenance, since main features are located within pump-stand above ground. Particularly widespread in Asia. Examples: No.6 pump and traditional designs.
ENVIRONMENTAL CONSIDERATIONS
Low ecological footprint technology, it only pumps limited water volumes from shallow aquifers. Use of these suction pumps might cause contamination if unclean water is used for priming. During severe droughts water might be too deep for using suction handpumps.
FINANCIAL CONSIDERATIONS
A household level suction handpump may cost USD 30-100. Maintenance costs are low. Depending on installation depth and drilling method, a pump including a tube well might cost USD 100-200.
TECHNICAL CONSIDERATIONS
Priming (pouring water on plunger) is needed at the start of operation. Maintenance includes regular greasing and checking of pump-stand parts, replacement of washers, cupseals and bearings. Major repairs include the welding of broken rising mains and cracks.

INSTITUTIONAL AND MANAGEMENT CONSIDERATIONS
Installation and maintenance is simple, facilities can be managed locally, without external support. For major repairs, like cracked or broken parts, a metal workshop and related skilled labor should be available in the vicinity of the pump.
SOCIAL & HYGIENE CONSIDERATIONS
Users should be aware of using clean water for priming when starting operation. Well contamination needs treatment step and may require awareness raising programs for efficient tackling. Example: Arsenic contamination of shallow wells in Bangladesh causes a public health crisis.

FIETS Sustainability principlesFinancial Sustainability - Delivery of products and services related to water, sanitation and hygiene is assured, because the activities are locally financed (e.g. taxes, local fees, local financing) and do not depend on external (foreign) subsidies.
Institutional sustainability - Institutions, policies and procedures at the local level are functional and meet the demand of users of WASH services. Role of actors are clear and their functioning effective. Multi-stakeholder approach.
Environmental sustainability - WASH interventions are viewed in the wider context of the natural environment and implementing an approach of integrated and sustainable management of water and waste(-water) flows and resources.
Technical sustainability - when the technology or hardware for the services is maintained, repaired and replaced by local people and it is not depleting the (natural) resources on which it depends for it’s functioning.
Social sustainability - appropriate social conditions & prerequisites are realized and sustained so current and future society is able to create livable communities. Demand-driven, inclusive, gender equal, culturally sensitive and needs-based.

The decision-support protocol
The decision-support protocol Applicable technology: green, as the screening options
make it an eligible technology. Applicable technology but with restrictions: yellow,
option may be suitable, but the chosen screening options indicate a limited applicability.
Not-applicable technology: red, as one or more of the screening options eliminate its use in the planned scenario.
Not relevant technology: white, any method where the no active screening applies.
