Increasing economic (production and consumption) activity, in effect, would boost the generation of solid wastes in any given community. Based on the City’s Environmental Code (City Ordinance No.1720-2011), “Solid Wastes” refer to all discarded household, commercial wastes, non-hazardous institutional and industrial wastes, street sweepings, construction debris, agricultural wastes, and other non-hazardous/non-toxic solid wastes.
The findings of the WAC Study in 2004 on individual solid waste generation of 0.6kg/person in a day may not be relevant today due to increase economic activity of the people living in Santa Rosa. Also, the Census Office (NSO) already issued an actual population of 284,640 in 2010.
The table shows that projected waste generation per day of the City of Santa Rosa until the year 2017. The total solid waste generation of the city with estimated population of 310,258 (2010), is about 186 metric tons per day based on the average rate of 0.6kg/person/day (WACS, 2004). An estimated 53% of the total wastes generated are recyclable.

The entire city lacks wastewater treatment facilities. The city resorts to discharging wastes into surface waters like local rivers and creeks. Consequently, Santa Rosa contributes to the unfavourable Class C status of Laguna Lake.
