The costs as shown in table 2 (above) are based on the provision of a basic level of water service, as defined by [[#WASHCost|WASHCost]]. A basic service implies that the following criteria have been realised by the majority of the population in the service area: People access a minimum of 20 litres per person per day, of acceptable quality (judged by user perception and country standards) from an improved source which functions at least 350 days a year without a serious breakdown, spending no more than 30 minutes per day per round trip (including waiting time).
The minimum expenditure on direct support required to provide a basic level of sanitation service ranges from US$ 0.5 to just over US$ 1.5 per person (2011 prices) (see table 3).

The costs as shown in table 3 (above) are based on the provision of a basic level of sanitation service, as defined by [[#WASHCost|WASHCost]]. A basic sanitation service implies that all the following criteria have been realised by the majority of the population in the service area: At least some members of the household use a latrine with an impermeable slab at the house, in the compound or shared with neighbours. The latrine is clean even if it may require high user eff ort for pit emptying and other long term maintenance. The disposal of sludge is safe and the use of the latrine does not result in problematic environmental impact.
When using these benchmarks (see table 2 and 3) local factors must be taken into account. For example, the lower cost ranges were generally, but not always found in India, while cost data from Latin America tends to be higher than the maximum ranges, but usually relates to higher service levels.
For both water and sanitation:
* If expenditure is lower than the minimum range, then there is higher risk of reduced service levels or long-term failure. A reduced service level means that one or more service criteria (e.g. access, quantity, use, quality and reliability) are not achieved. Service criteria can vary according to country context and norms.
* In the [[#WASHCost|WASHCost]] research, use of latrines and reliability of services tend to be lower when recurrent expenditure on things such as operation and maintenance is low.
* If expenditure is higher than the maximum range, an affordability check (for both users and providers) might be required to ensure long-term sustainability.
* If a basic level of service is being delivered and expenditure is outside the cost benchmarks, then there may be context-specific explanations; such as the service is in a densely-populated area with economies of scale, or, conversely, the area is difficult or remote to reach.
====Expenditure on direct support in Mozambique between 2008 –2011====
In 2008 a new approach for direct support aimed at supporting communities to improve their capacities to manage water supply and hygiene and sanitation conditions, called PEC zonal, was introduced in Mozambique in 18 districts. The PEC Zonal approach entails that a single (non-profit) organization or consultant is contracted by government to carry out all promotion of participation and education of the community in a district during a whole year (Zita and Naafs, 2011). The approach was scaled up country-wide in Mozambique from 2011.
The [[#WASHCost|WASHCost]] Mozambique project examined 94 PEC zonal contracts signed between 2008– 2011. Based on Zita and Naafs (2011, 1) the average cost of PEC zonal activities is 3,025,000 meticais (US$ 103,000) or 33 meticais (US$ 1.10) per person per year. No correlation was found between the cost of PEC zonal and variables such as district population, size of the district (km2), population density and water coverage in a district (see figure 2). The height of expenditure on direct support is therefore not directly related to these factors.

The benchmarks have been derived from the WASHCost project dataset and the best available cost data from other organisations all over the world. The benchmarks are useful for planning, assessing sustainability from a cost perspective and for monitoring value for money.

* WASHCost was five-year action research programme, running from 2008 to 2012. The WASHCost team gathered information related to the costs of providing water, sanitation, and hygiene services for an entire life-cycle of a service - from implementation all the way to post-construction. The WASHCost programme was led by IRC International Water and Sanitation Centre with several partners to collect data in the rural and peri-urban areas of Burkina Faso, Ghana, India, and Mozambique. For more information see www.washcost.info
* The Costing Sustainable Services online course was developed to assist governments, NGOs, donors and individuals to plan and budget for sustainable and equitable WASH services, using a life-cycle cost approach. The Life-cycle cost approach is a methodology for costing sustainable water, sanitation and hygiene service delivery and comparing the costs to the level of service received by users.

* Triple-S (Sustainable Services at Scale) is a six-year, multi-country learning initiative to improve water supply to the rural poor. It is led by IRC International Water and Sanitation Centre. The initiative is currently operating in Ghana and Uganda. Lessons learned from work in countries feeds up to the international level where Triple-S is promoting a re-appraisal of how development assistance to the rural water supply sector is designed and implemented.
