The firm EDE International SA, has developed for over 15 years a strong competence in communication and awareness for the water and sanitation sector, in urban and rural areas, in Senegal and in other countries of the world. 'West, Central and East Africa.                   
                   The main tasks related to social marketing and IEC, including the design and implementation of communication / awareness campaigns as well as the management of sanitation demand as well as the design of promotional materials, are among the main activities of the EDE firm.                 


Our team is involved in the implementation of several pricing studies, based on a pricing structure model that allows quantitative testing of four efficiency criteria with any form of pricing of water consumption for households: flat rate fee, fee fixed plus uniform tariff with or without subsidy, progressive tariffs by consumption band, modification of band thresholds, etc.                   
                  This model makes it possible to assess the impact of the price of the service on household consumption and to optimize this consumption under the fourfold constraint on turnover to be achieved, possible cross-subsidies from professional subscribers (depending on the tariff tested), the tariff structure tested and the ability to pay of households.                   
                  Household consumption is assessed on the basis of the distribution of billed volumes (consumption file per subscriber to supply) and that of household income.                   
                  To measure the impact of pricing on consumer behavior, it is necessary to have their consumption and income curve at this level.                 

Information Education Communication

IEC et Marketing Social - SERVICES:


The marketing and communication strategy is the defining part of a project.                   
                   EDE specializes in water and sanitation promotion programs, has developed relevant campaign methodologies adapted to different social contexts.                   
                   Through the diagnosis, segmentation, targeting, positioning and definition of the 4 Ps, EDE International largely integrates sanitation marketing in the progress of its various projects.                 


                  Hygiene awareness remains a concern of donors and governments in order to reduce the mortality rate of young children and the rate of diseases linked to faecal hazard.                   
                  EDE International, had to design and run during these missions, awareness campaigns on good hygiene practices and maintenance of sanitation facilities.                   
                  The training and deployment of information relays from the heart of the target, makes it possible to effectively sensitize the populations through didactic and interactive communication tools as well as community sharing sessions.                   
                  It’s like this:                   
                  . Establish direct and interactive contact with target populations and other beneficiaries actors and vector communication groups through informal networks                   . Create the conditions for a change in behavior through an IEC approach thanks to the recurrence of contacts, exchanges, education sessions, training and replication of messages, good practices, and good perception of opportunities of the project.                   . Improve knowledge, understanding and development of good practices in sanitation, health hygiene, environmental management.


Any IEC, social marketing and communication project cannot achieve its objectives and target without the appropriate communication media ticket.                   
                  EDE International designs and produces relevant and varied information tools according to the target and the objective. It therefore offers different types of tools:                   
                  . Informative supports , especially of proximity facilitate the assimilation and the comprehension of the audience, it is inter alia, aids and teaching aids or audio / scripto / visual tools (roll- up, institutional brochure, flyer, poster, radio or TV program, leaflet, etc.)                   
. Teaching aids are used for educational and educational purposes, just like informational aids, they facilitate the assimilation and understanding of the audience. These are the training manual, the user guide, the model, the picture box, the sign, etc.)                   
. Promotional materials aim to promote, among other things, good hygiene practices and popularize sanitation works and connection to the drinking water network. The tools used for this type of support are the notebook, the t-shirt, the cap, the radio spot, the film, the catalog, etc.)                 


                  Whether in improved toilets or in water connection, EDE International has solid experience in handling demand in communication and IEC projects.                   
                  Generating demand is a decisive step in a project. The request must not be generated too early or too late and for this a meticulous organization adapted to the environment must be put in place.                   
                  The firm offers optimal management of demand so that the deadlines for generating and satisfying demand are respected.                   
                  The organization and management of demand is a key point of this type of project and intends to implement it through a relevant strategy adapted to the targeted area and the specifics of the project. Indeed, certain data, such as the conditions of access to the connection, the socioeconomic condition of the households, the adhesion of the representatives of the population to the project through targeted meetings, are essential to define an effective management plan for the request.                   

                  At EDE International, organizing demand has three stages:                   
                  . Generation, stimulating demand                   
                  . Management, processing of the request                   
                  . Monitoring and satisfaction of demand                   
                  At the end of these different stages, the Firm has a large household database that can be used by the client in the future for similar projects.                 


In projects with strong social connotations, advocacy plays an important role in the mobilization of the most influential actors and the social validation of the project. In short, it is a question of harnessing the power of influence of opinion leaders and other opinion leaders to draw the rest of the population into a sort of diagonal of good practices. An advocacy campaign mainly targets these objectives:                   
                  . Involve influential target groups in the credibility of the project                   
                  . Mobilize financial support from donors and other patrons to support household efforts in expanding access to basic social services                   
                  . Highlight the messages of good practice carried by individuals or socially recognized groups capable of generating a mimetic effect, a start or a revival of dynamism.                   
                  EDE takes place according to the context and the objectives of the projects, different types of advocacy:                   
                  . Institutional advocacy mainly targeting the members of the steering committee and the technical committee                   
                  . Social advocacy targeting social actors (NGOs, GPF, ASC, religious and traditional leaders, emblematic figures of sport and culture)                   
                  . Professional advocacy aimed exclusively at entrepreneurs and private companies located in the project intervention area                   
                  . Community advocacy (neighborhood or neighborhood groups) targeting opinion leaders and neighborhood leaders                   
                  . Media advocacy consisting of broadcasting mobilization messages and good practices on television and radio                   
School advocacy involving RNs, IDENs, etc.

Pricing studies

Optimal pricing for drinking water - Services


An optimal pricing structure is obtained by successive approximations by simulating consumers' responses to different pricing options. These responses are assessed in relation to the following efficiency requirements:                   
                  1- financial: correspond to the financial balance of services;                   
                  2- economic: meet demand for water and sanitation services;                   
                  3- equity: maximize consumer solidarity with the poorest households;                   
                  4- readability: make it easier for consumers to understand;                   
                  5- implementation: minimize the cost of invoicing;                   
                  6- environmental: preserve the resource and encourage responsible consumption.                   

                  These requirements are most often contradictory and the optimal pricing structure is one that optimizes all the criteria with equivalent or different weights depending on the desired directions.                   
                  Progressive block pricing offers the following advantages:                   
                  . Encourage water saving, which contributes to a more sustainable use of the resource and an optimization of production investments;                   
                  . Adjust to marginal cost, which contributes to rational behavior, with the highest tariff approaching marginal cost and the average tariff covering the average cost of operations and capital;                   
                  . Facilitate access for the poorest households, which contributes to positive externalities (public health).                   
                  However, it presents a set of constraints to be taken into account, in order to mitigate them as far as possible:                   
                  . its application is not very flexible. For example, the first tranche is often determined on the basis of the basic needs (30 l / d / inhabitant) of a medium-sized household. However, this standard is not suitable for households whose size differs from the average. It is the same, in the case of collective meters or sharing of a connection by several households (case of rentals). Poorer households can therefore pay a higher average rate than wealthy households with individual connections;                   
                  . if the tariff for the upper bracket is higher than the marginal cost, it can lead to a reduction in economies of scale and cross-subsidization, large consumers preferring, as far as possible, to self-supply by direct withdrawals from water resources;                   
                  . positive externalities are not measurable and can compensate for negative externalities, such as pollution of the resource or the prevalence of diseases from contaminated water.


Generally, the policy of enrolling users is implemented through programs of access by special connection which aim at a rapid integration of households into the fabric and urban society, and to reinforce the financial viability of the service through densification. of the service.                   
                  The experience of incentive programs for specific connections in many countries shows that it is not possible to discriminate between households, since the eligibility criteria applied (areas with lots, title of occupation required) often tend to favor "settled" households, which can at least partially pay for their connection.                   
                  The help of the particular connection must therefore apply regardless of the area (allotment or not lot), the characteristics of the habitat, the occupation status or the household income.                   
                  The definition of exclusion criteria is an essential result of surveys on the ability and willingness to pay of households with the aim of improving the effectiveness of public aid and preventing the poorest households from being excluded.                   
                  Serving the poorest households involves the implementation of collective and temporary water supply systems, such as standpipes, mini-grids, prepayment kiosks, collective distribution points, course connections, etc.                   
                  These are permanent or temporary systems pending the possibility of financing a particular connection, or combined spontaneous neighborhood structuring programs (water, electricity, liquid and solid sanitation).                   
                  This type of program aims to fight against the poverty of populations not connected by special connections, which are supplied with drinking water by resellers of water at high prices.                   
                  These collective service programs are sometimes difficult to combine with a connection subsidy mechanism, because the latter can reduce their effectiveness: decrease in the income of fountains and dealers, increase in the number of inactive standpipes with the intensification of individual connections. .
