For the countries that provided complete information on sector investments it is interesting to note an increase in the ratio of external contribution to the total investments in the country. These figures vary from 21% in Panama to 97% in Haiti, with an average of approximately 45% in comparison to 30% reported in the previous decade.

The investments in sewerage and sanitation continue to lag behind those made for water supply. The available information indicate that the sewerage and sanitation investments approximate 50% of the water supply investments during the period whereas to meet the demand in a 20 year time they should be 200% of the water investments.

Table 5.27 shows the projected investments by the countries for the period 1996-2000. Information on sewage costs and tariffs are shown in Tables 5.28 and 5.29.
