K&M is advising WEB Aruba, the utility responsible for providing water and electricity in Aruba, on evaluating options for the development of a seawater reverse osmosis plant. K&M is investigating whether the least cost option would be for WEB to extend its current water supply contract with Suez or build a new water treatment facility. K&M gathered data and reviewed information, including water demand and production data, water purchase agreements, and WEB’s preexisting internal analysis of water supply options. K&M developed an options evaluation model that includes seasonally adjusted demand and production and calculations of the least cost of water (LCOW).
