The majority of water usage at this office <br />facility is domestic, estimated at 88 % of total water usage. Installation of flow restrictors <br />and faucet aerators appear to be a cost effective way to reduce water use at this facility, with <br />payback of costs occurring in about one year. It is recommended that these retrofits be <br />implemented. <br /> <br />6. <br />
