**4.6.3 Scenario three**

To be able to provide the per capita use of 67 l per capita per day at 2030 and be able to provide the same water services at the level of 135 l/capita/day of 2005, the following programs need to be implemented at the residential sector. These programs will save a total of 102,776,076 m3 which is the difference between the projected gross residential use of year 2005 of 105,379,575 m3 and the projected gross residential water use of 208,155,650 m3 if the

water use was increase to 135 litre/capita/day. Savings are mainly based on savings from end uses summed across the total population according to the following assumptions as shown in Table 10. The programs include: retrofitting 50 % of the toilets, retrofitting 50% of the showerheads, retrofitting 50 % of kitchen and bath faucets, finding and fixing leaks, installing efficient washing machines with a percent of 20%, turning 20% of the irrigation systems in gardens to drip irrigation systems, growing low water consuming landscapes or crops, installing greywater systems for outdoor use with 20% coverage, installing rainwater harvesting systems for outdoor use with 20% coverage, installing greywater systems for indoor use with 17 % coverage, installing rainwater harvesting systems for indoor use with 25 % coverage.
