Designed in collaboration with the US Environmental Protection Agency (EPA), the project also included the construction of a new reclaimed water distribution network and the construction of Rapid Infiltration Basins for groundwater recharge. At a project cost of $US344 million, financed primarily through municipal bonds complemented by a grant from the US EPA, it succeeded in eliminating discharges to the lake thereby improving its water quality. It also reclaimed a total volume of 58 million m3 of water per year.
