It is the only outlet of the lake but serves also as an inlet whenever the lake level is lower than Manila Bay. Sources of surface recharge 21 Major Tributaries 14% Pagsanjan-Lumban River 7% Sta. Cruz River 79% 19 remaining tributary rivers Only Outlet Napindan Channel connects the lake to Manila Bay •The lake is life support system Laguna de Bay: multi-use resource to about 13 million people •3.5 million of whom live in 29 lakeshore municipalities and cities Fisheries 2 It is the major source of freshwater fish in Dominant use for fishery .

Is Laguna de Bay a safe source of water for This is characterized by: drinking? • Increasing trend in BOD primarily due to domestic (close to 80%) and industrial wastes (some 11.5%), and as a result of Pasig River backflow. Nevertheless, the Lake’s BOD concentration is still within the criterion. (Laguna de Bay Environment Monitor, 2005) • The Lake provides safe drinking water with appropriate treatment. (LLDA Case Study on • Seasonal fluctuations in nitrate and phosphate concentration. Lack of centralized or localized sewage treatment perpetuates inflow of nitrogen Drinking Water Supply with LdB as Raw & phosphorous which brings about eutrophication. (Millennium Philippine Sub-Global Assessment, 2005) Water Source; Netherlands funded Sustainable Development of LdB • There are some traces of heavy metals in Lake water and sediments, Environment Project, 2000-2003) although concentration is still within prescribed safe levels. (LLDA-UP NIGS Study on Sedimentation Pattern, 1999) • Decreased counts of aquatic plants. (LLDA Monitoring Sampling Data) • The Lake is undergoing rapid shoaling. Average depth is 2.5m in 2003 as compared to 2.78m in 1973. (LLDA-UP NIGS Study on Sedimentation Pattern, 1999; Sustainable Development of the LdB Environment Project, 2000-2003) 5 Current Situation… Laguna de Bay as an adequate source of bulk The Lake has become the repository of human and raw water for drinking industrial wastes from Metro Manila and other surrounding localities. • The Lake has an average volume of 2.25B m3 (SOGREAH Report, 1973) • 1000MLD* (400 MLD for water supply & current 600 MLD for irrigation & other uses) is projected to decrease water level by only 1.1 mm/day or 13.3 cm during dry months (Jan-April). This is only 9.5% of total annual average water inflow from tributaries. (Sustainable Development of the LdB Environment Project, 2000 -2003) • Different alternative engineering schemes have already been drawn where the Lake and Pagsanjan River are considered as probable raw water sources. (Study on Engineering Alternatives for the 300 MLD Bulk Water Supply Project, September 2000; Sustainable Development of the LdB Environment Project, 2000 -2003) • Existing MWSS water supply sources are insufficient to meet the requirements of its service areas. - In April, 2004 MWSS solicited proposals for the delivery of 400 MLD treated bulk water to its concessionaires, without limiting the source to LdB (MWSS Consolidated FS on 400 MLD Bulk Water Supply Project; NEDA Report). - MWSS is yet to await DOJ - OGCC opinion whether to proceed with the supply of 300 MLD thru BOT *Million Liters per Day Organic Waste Profile in the Lake 2005 Water Mondriaan’s Monthly Summary Assessments of the Laguna de (As of 2004) Bay’s Overall Water Quality Status* Agriculture Forest 9.8% 0.8% Industry 11.5% Domestic 77.9% 6 Critical Areas that need Intervention Sapang Baho River … On Indiscriminate Reclamation And Encroachment of Shoreland Areas MangangateRiver Tunasan River San Pedro River TCC – Total Coliform Count BOD-Biochemical Oxygen Demand DO – Dissolved Oxygen N Proclamation No. 704 • Issued by Pres.
