An energy audit by the German government has revealed that insufficient and inconsistent water supply can be attributed to high energy costs which take up to 35 percent of the revenue streams threatening their viability. The audit carried out on 29 water companies shows that the annual cost for the companies to produce a total output of 108 million cubic meters of water is 964.7 million shillings. Items found to make the cost soar so high include old pumping machinery as well costly lighting systems used by the water companies. With the recommendations from the audit, water companies can save up to 103.8 million per year over an average two year pay-back period. This would directly impact on the end users through lower water charges.
