City officials will have to wait before they can test a new evaporation suppressor on Lake Arrowhead.
Shipments of the WaterSavr product have not made it to Wichita Falls as of Monday morning.
Last week city council agreed to spend over $350,000 to do a 70 day test of the product. According to city officials, WaterSavr can slow down evaporation by as much as 30-percent. Public Works Director Russell Schreiber said if the product cuts down evaporation by 10-percent, the city can save as much as 4-million galls of water a day.
