Standards, technology and sustainability

There are many examples in the developing countries (DCs) of environmental standards being set at high levels that cannot possibly be met in the prevailing economic conditions. Such standards are counter-productive; responsible operators who would work towards reasonable standards are turned off and evade the standards. This situation arises because the selected standards tend to be copies of existing standards from industrialized countries where most of the work of developing standards has taken place. The standards they copy are the current high standards that are affordable in the West, but are not affordable in the DCs. A similar situation exists with respect to technology. Designs that work well in the West tend to be copied but do not function well in the DCs because the level of expertise needed to ensure proper performance does not exist, and cannot be recruited and retained at the low wage levels that most authorities are able to pay. The remedy in both cases is to ensure that standards are appropriate and that the constructed facilities will be appropriate and sustainable. They can be sustainable only if adequate funds are assured for a sound program of operation and maintenance. With the ever increasing competition for the use of scarce water resources, all control agencies have a duty to maximize the use of the water they are allocated. For urban water supply systems this means ensuring tight control of UFW. Privatization of UFW control may offer significant benefits for the DCs and merits serious consideration.
