Briefing Note 1a - Life-cycle costs approach: costing sustainable services, November 2011

Estimating the true cost of extending sustainable WASH services to poor households is an on-going problem for WASH service providers. How can we achieve the most while spending the least? WASHCost addresses this challenge by developing and testing the life-cycle cost approach in rural and peri-urban areas of developing countries. Using the life-cycle cost approach enables service providers to consider a wider range of costs. The life-cycle cost approach compares effectively the different WASH delivery systems within a district, country or region. The approach can therefore be tailored to specific needs and critical issues in different countries.

Briefing Note 1b - Services are forever: The importance of capital maintenance in ensuring sustainable WASH services, August 2010

A dearth of data, methodologies and analyses to understand the full life-cycle costs of WASH maintenance is a major challenge faced by the water and sanitation sector. This briefing note introduces the concept of capital maintenance expenditure as a way forward to filling this gap. It is a valuable resource for policymakers, practitioners, donors and researchers working in this area.

Briefing Note 1b - Pour des services pérennes: Le rôle crucial des dépenses de renouvellement et de réhabilitation d’AEPHA (2010)

Cette note de synthèse a pour but de mettre en avant et de promouvoir un concept crucial pour garantir le fonctionnement continu des services d’approvisionnement en eau potable, d’hygiène et d’assainissement (AEPHA). Elle explique l’importance de la collecte, de l’analyse et de la budgétisation des dépenses de renouvellement et de réhabilitation, ainsi que leur relation avec les dépenses d’investissement et les dépenses de fonctionnement et d’entretien courant. La bonne compréhension et l’utilisation de ces notions a pour objectif d’attirer l’attention des planificateurs, des bailleurs de fonds, des gestionnaires de service, des régulateurs et des usagers sur l’ensemble des dépenses permettant d’assurer un service efficace et durable, sachant qu’en général, l’attention se focalise sur la construction de nouveaux équipements.

Briefing Note 1b - (em Português) Serviços para sempre: A importância da Manutenção do Capital (CapManEx) na garantia de serviços sustentávei...

A escassez de dados, metodologias e análises para compreender os custos do ciclo de vida dos custos de manutenção em ASH é o grande desafio enfrentado pelo setor de água e saneamento. Esta nota informativa introduz o conceito de despesas de manutenção como um caminho a seguir para o preenchimento desta lacuna. É um recurso valioso para os decisores políticos, profissionais, doadores e investigadores que trabalham nesta area.

Briefing Note 1c - The cost of capital: Costs of financing capital expenditure for water and sanitation, September 2011

This briefing note investigates the cost of financing capital expenditure, usually referred to as the cost of capital, and explains why it is one of the building blocks that make up the total costs of providing water and sanitation services that last. Highly subsidised costs of capital with very long repayment periods may not be recognised as a cost, particularly when the time frame falls beyond the scope or years of most planners’ and politicians’ involvement.

Briefing Note 2 - Decentralisation and the use of cost data in WASHCost project countries, June 2010

WASH services are often planned and delivered based on capital costs only. This briefing note looks at the WASHCost method of needing to include maintenance and indirect support costs or life-cycle costs.

It is invaluable help to authorities wanting to develop a life-cycle costs approach and includes a review of decentralisation in the WASHCost areas.

Briefing Note 3 - Applying the life-cycle costs approach to sanitation, December 2011

This briefing note presents an application of the life-cycle costs (LCCA) approach to sanitation in rural and peri-urban areas in four different countries— Andhra Pradesh (India), Burkina Faso, Ghana, and Mozambique. The document compares the differences between the financial costs of traditional and improved latrines, and the quality of service delivered to users.
