The Laguna Lake Development Authority (LLDA), one of the attached agencies of the Department of Environment and Natural Resources (DENR), is responsible for the preservation, development, and sustainability of the Laguna de Bay and its 21 major tributary rivers.

The Laguna Lake Development Authority was created by virtue of Republic Act No. 4850 (as amended by Presidential Decree 813), entitled: AN ACT CREATING THE LAGUNA LAKE DEVELOPMENT AUTHORITY, PRESCRIBING ITS POWERS, FUNCTIONS AND DUTIES, PROVIDING FUNDS THEREOF, AND FOR OTHER PURPOSES.

Since 1993, LLDA is attached to the Department of Environment and Natural Resources (DENR) pursuant to EO 149, for administrative supervision and policy alignment.


The Laguna Lake Development Authority (LLDA) was created by the virtue of Republic Act No. 4850 (as amended by Presidential Decree 813), entitled AN ACT CREATING THE LAGUNA LAKE DEVELOPMENT AUTHORITY, PRESCRIBING ITS POWERS, FUNCTIONS AND DUTIES, PROVIDING FUNDS THEREOF, AND FOR OTHER PURPOSES, on 1969.

The Authority leads, promotes, and accelerates sustainable development in the Laguna de Bay Region through the enforcement of laws and provisions on environmental management, with provisions on water quality monitoring, conservation of natural resources, and community-based natural resources management.

Showcasing the symbiosis of man and nature through the utilization of the Integrated Water Resource Management in Laguna Lake Region, LLDA aims to preserve the ecological integrity and to promote economic growth with equitable access to resources.

As stated in the Chapter 1 of Section 1 in the RA 4850: "It is hereby declared to be the national policy to promote, and accelerate the development and balanced growth of the Laguna Lake area and the surrounding provinces, cities and towns hereinafter referred to as the region, within the context of the national and regional plans and policies for social and economic development and to carry out the development of the Laguna Lake region with due regard and adequate provisions for environmental management and control, preservation of the quality of human life and ecological systems, and the prevention of undue ecological disturbances, deterioration and pollution."

The Laguna Lake Development Authority (LLDA) was established in 1966 as a quasi-government agency that leads, promotes, and accelerates sustainable development in the Laguna de Bay Region.[1] Regulatory and law-enforcement functions are carried out with provisions on environmental management, particularly on water quality monitoring, conservation of natural resources, and community-based natural resource management.[2]

Its mission is to catalyze Integrated Water Resource Management in the Laguna de Bay Region, showcasing the symbiosis of man and nature for sustainability, with focus on preserving ecological integrity and promoting economic growth with equitable access to resources.

While water levels in Angat and La Mesa reservoirs remain at alert level, Laguna de Bay boasts of its abundant water that is now tapped by Maynilad Water Services, Inc. to supply the water needs of the communities in Muntinlupa, Las Pinas and nearby areas.

The LLDA, as early as August 7, 2009, approved the water permit application of Maynilad to allow the West Zone concessionaire to abstract 100 million liters per day of lake water to be made available for domestic consumption. Maynilad started the production of 50 MLD last June 2010 and expects to produce 100 MLD in September this year using surface raw water from Laguna de Bay.[3]

Environmental Management Program[edit]

LLDA puts into action systems and programs such as Environmental User Fee System (EUFS), Public Disclosure Program (PDP), the Appropriation and Utilization of Surface Waters (Surface Waters) for the management of the lake waters and tributaries that flow into the Lake, to ensure their proper use and maintenance for the sustainability of the ecosystem.

The Environmental User Fee System[edit]

To realize the objectives of the creation of LLDA, the agency implemented policies to curb the possibility of stressing the lake’s assimilative capacity. The most recent policy was the Environmental User Fee System (EUFS). The EUFS was implemented by virtue of LLDA Board Resolution 22 in 1996. The objective of the policy was to “…(reduce) the pollution loading in to the Laguna de Bay by enjoining all discharges of liquid wastes to internalize the cost of environmental degradation…”. Formally, the said board resolution aptly defined the EUFS as a “market–based” policy instrument aimed at reducing the pollution loading in the lake. As such, companies found to have unusually high concentration of pollutants in their emissions, need to pay fines or lake “user–fees”.

The system encourages companies to invest in and operate pollution prevention and/or abatement systems in their establishment. Applying the "polluter pays principle", the system effects direct accountability for damage inflicted on the integrity of the Laguna de Bay region thereby encouraging individuals and business establishments to internalize into their decision-making process the environmental impacts of their day-to-day activities. The EUFS covers all enterprises in the administrative jurisdiction of LLDA that discharge wastewater in the Laguna de Bay system. These include commercial and industrial establishments; agro-based industries and establishments (such as swine farms and slaughterhouses); clustered dwellings (i.e., residential subdivisions); and domestic households[5]

Under the EUFS, a firm is required to secure a discharge permit which is renewed annually at the LLDA. The discharge permit effectively allows the firm to discharge its wastewater to the lake or through its main tributaries. The discharge permit gives the establishment a legal right to dispose their waste water in the Laguna de Bay region. Wastewater is basically sewage, storm water, and water used around the community, including firms.

Domestic wastewater includes black water, or wastewater from toilets, and gray water, which is wastewater from all sources except toilets. Black water and gray water have different characteristics, but both contain pollutants and disease-causing agents that require monitoring. Nondomestic wastewater is generated by offices, businesses, department stores, restaurants, schools, hospitals, farms, manufacturers, and other commercial, industrial, and institutional entities. Storm water is a nonresidential source and carries trash and other pollutants from streets, as well as pesticides and fertilizers from yards and fields.[6]

The EUF is paid for the amount of pollution that is discharged into the tributary rivers in the Laguna de Bay region. It is composed of a fixed fee and a variable fee. The fixed fee covers the administrative cost implementing the Environmental Users Fee System and is based on the volume of wastewater that is discharged.

According to LLDA Board Resolution 33, as amended, the fixed fee is different for those firms that discharge wastewater without or with heavy metals.

Wastewater without heavy metals:

Fee Volume of Wastewater Discharge
PhP 24,000 More than 150 m3 per day
PhP 16,000 Between 30 and 150 m3 per day
PhP 8,000 Less than 30 m3 per day

Wastewater with heavy metals:

Fee Volume of Wastewater Discharge
PhP 12,000 Less than 150 m3 per day
PhP 24,000 More than 150 m3 per day

The fixed fee also depends on the volume of wastewater discharged. For a firm that discharges wastewater without heavy metals, the fee is PhP 24,000 if the discharge is more than 150 m3 per day, PhP 16,000 if the discharge is between 30 and 150 m3 per day, and PhP 8,000 if the discharge volume is less than 30 m3 per day. Those firms that discharge wastewater with heavy metals pay higher fixed fees. The fee is PhP 12,000 for a firm that discharge less than 150 m3 of wastewater with heavy metals per day and PhP 24,000 if the discharge is more than 150 m3 per day.

The variable fee is calculated with the reference to the biochemical oxygen demand (BOD5) loading as well as to the volume and concentration of the wastewater being discharged. According to the same policy, the variable fees is PhP 30 per kilogram of total BOD5 when the BOD5 concentration is less than 50 milligrams per liter and PhP 30 per kilogram of total BOD5 when the BOD5 concentration is greater than 50 milligrams per liter.

Public Disclosure Program (PDP)[edit]

In addition to the EUFS, the LLDA under the PDP assesses the environmental performance of regulated establishments and Local Government Units (LGUs), and discloses the results thereof to the public. This mechanism is intended to motivate the industrial sector and LGUs to reduce their pollution.

Surface Waters Program[edit]

Under the Surface Waters program, Water Permitting, Registration, and Monitoring programs are established and operated for the extraction of waters that are naturally open to the atmospheres, such as rivers, lakes, and streams within the Laguna de Bay Region.

Watershed Management Program[edit]

To abate the further degradation of the Laguna de Bay Watershed, the LLDA instituted various programs and strategies for reforestation of the denuded watersheds. Part of these programs and strategies are the River Rehabilitation Program, and the Shoreland Management Program.

Laguna de bay Watershed Greening Program[edit]

The LLDA contributes to the NGP objectives, which include planting 1.5 billion seedlings in 1.5 million hectares of public lands nationwide, from 2011 to 2016. The NGP also aims to improve water quality in rivers and irrigation of farm lands, reduce flooding, absorb carbon dioxide from the atmosphere, and as support for the expansion of a wood-products economy. Using its own resources, the LLDA produces tree seedlings for distribution to LGUs and other beneficiaries for planting in their respective areas. Further, the Authority undertakes reforestation activities in denuded/designated areas in critical sub-watersheds. Rapid economic growth, continuing industrialization and unabated influx of informal settlers have resulted in a variety of social and environmental impacts in the area, which brings significant changes in the Laguna de Bay and its watershed. Deforestation and soil erosion are known to be the main contributors to siltation in the Laguna Lake. Apparently, heavy siltation has reduced the lake’s present depth to an average of about 2.5 meters from 12 meters decades ago. Study revealed that an estimated of some four (4) million tons of suspended sediments enter the lake annually, leading to an average net accretion of 0.50 cm per year (SDLBE-Nauta, 2002). The heavy siltation of the lake has detrimental effects to ecology and economy. In a rapid valuation of the Lake’s benefits to society if returned to its pristine state, PHP 3.6 billion in annual benefits is lost due to the deterioration of the Lake’s quality (Arcenas, 2012).

Realizing the urgency to reduce the impact of global warming, the Laguna Lake Development Authority (LLDA) has spearheaded various watershed rehabilitation in Laguna de Bay Region through reforestation. As early as the 1990’s, a permanent agro-forestry nursery was established within its premises in Calauan, Laguna, which provides seedling requirements for its own tree planting activities as well as for other stakeholders like LGUs, industries, river councils and other organizations which were conducting similar activities. Taking the lead, LLDA has reforested a number of areas within its jurisdiction including the road stretching along the boundary of Baras and Tanay in the province of Rizal. The Pangil Bamboo Farm in Laguna was also conceived giving its locals livelihood.

The National Greening Program[edit]

Executive Order No. 26 is President Benigno Simeon C. Aquino’s response to worldwide concern on global warming. Issued on February 24, 2011, it aims to plant 1.5 billion trees in 1.5 million hectares within 2011 to 2016 to areas covering forestlands, mangrove and protected areas, ancestral domains, civil and military reservations, urban areas under greening plan of LGUs, inactive and abandoned mine sites, and other suitable lands within public domain. The NGP also seeks to improve quality of various waterways including irrigation for farmlands, reduce potential for flooding, soak up carbon dioxide out of the atmosphere, and lay the foundation for an expanded wood products economy. All government agencies, GOCCs and institutions, including local government units, will provide full support to the program.

Commitment of LLDA to the National Greening Program Even before the issuance of E. O. 26, LLDA has been doing watershed rehabilitation within the Laguna de Bay Region.

In 2011, additional nursery was established on LLDA property in Lumban, Laguna to augment the growing demand for forestry.

From 2011-2014, the authority produced a total of 503,683 seedlings wherein 345,191 seedlings were planted and/or dispersed to different stakeholders within the Laguna de Bay region. In 2013, seedlings production in both nurseries reached to a total of 111,248 seedlings wherein a total of 51,211 seedlings were planted and/or dispersed to various stakeholders within the Laguna de Bay region. By 2014, a total of 200,511 seedlings were produced and with a total of 229,934 seedlings planted and/or dispersed to LGUs, industries and various civic organizations.

Aside from the production of planting stocks and field planting, the LLDA supports the NGP by means of providing technical and extension assistance to stakeholders such as species selections, site identifications and land preparations. In addition, the LLDA recognizes the significance of the involvement of the community in the success of the project. Therefore, the agency is mobilizing the sectors in the private and public areas to become part of the program.

In order to sustain the impact and significance of NGP, LLDA is committed to create and implement supportive policies and utilize integrated methods to resource management and empower local people to ensure equitable sharing and responsibilities in caring for our environment.

River Rehabilitation Program[edit]

The River Rehabilitation Program takes into consideration the effects of water quality and quantity to the ecosystem. Under the program, the LLDA has organized River Basin Councils all over the Region. The “Environmental Army,” an aggrupation of community volunteers, has been established and mobilized to help LLDA in various river clean-up operations. The LLDA has transformed the River Councils and the Environmental Army into empowered partners in environmental governance throughout the lake region.

Shoreland Management Program[edit]

The Shoreland Management Program is designed to control pollution and nuisance through the elimination of incompatible elements and uses of the shoreland, through the LLDA Board Resolution No. 23, Series of 1996, which defines and regulates the use and/or occupancy of the Laguna de Bay Shoreland Areas.

Fisheries Development[edit]

Prior to 1996, the use of lake resources for aquaculture caused the uncontrolled increase in fish pens and fish cages, decline in lake productivity, and conflicts between marginalized fisher folks and fish pen operators. These socio-economic and environmental problems in Laguna de Bay prompted LLDA to formulate and approve the Zoning and Management Plan (ZOMAP) on January 1996.

Zoning and Management Plan (ZOMAP)[edit]

Through the ZOMAP, lake resources are equitably delineated and allocated to various users for aquaculture operations, navigation, and open fishing. At the national level, the aquaculture operations in Laguna de Bay contributes significantly to fishery production (Israel, 2008). Lake productivity is further improved through the maintenance of Rayap Fish Sanctuary in Talim Island, Rizal; Tabon Fish Sanctuary near Calamba, Laguna; and the Muntinlupa Fish Sanctuary in Muntinlupa City. With the assistance of the Bureau of Fisheries and Aquatic Resources, regular lake seedings are conducted in these sanctuaries.

LLDA is assisted by the Fisheries and Aquatic Resources Management Councils, Philippine National Police, Coast Guard, and other groups in the enforcement of fishery laws, rules and regulations in Laguna de Bay.

Community Development[edit]

The LLDA serves to maintain and improve the ecosystem of the Lake and the Region for sustainability, while taking into consideration the importance of the development of the people and community surrounding Laguna de Bay through community-based projects.

LLDA continuously works not just to protect the environment, but also to help improve the economy and the lives of the residents within the Region through various livelihood projects.

In 2012, LLDA signed a Memorandum of Agreement with the Department of Trade and Industry, Region IV-A, and the Asian Social Institute to create a bamboo and water hyacinth livelihood program for identified groups, primarily the fisherfolk families of the Laguna Lake Region. This project also aims to promote women and youth empowerment, community development, and sound environmental management.

Bamboo for Life[edit]

The Bamboo Negosyo Village, a project of LLDA since 2008 under its Laguna de Bay Watershed Bamboo for Life Program, establishes bamboo plantations in Lumban, Bay, and the mountainous areas of Pangil and Paete in the province of Laguna, and around the shoreland area in Taguig City. This project provides an alternative livelihood to the project co-operators through various bamboo enterprises, and additional incentives are also given through the provision of bamboo houses for each beneficiary family.


In partnership with various stakeholders, the LLDA established the river rehabilitation program “Adopt-A-River,” which is envisioned to protect and rehabilitate the various river systems through river segmentation, community participation and involvement, information, education and motivation campaigns, establishment of ecoparks, and development of a sustainable funding mechanism.

Research Programs[edit]

In support of LLDA’s mandate and various programs, the Decision Support System (DSS) and Water Quality Monitoring (WQM) Program are implemented to aid in monitoring and relevant policy decision-making.

The DSS, introduced by the Royal Government of the Netherlands through a funding for the Sustainable Development of Laguna de Bay Environment (SDLBE) Project in 2000, integrates state-of-the-art software tools to provide an adequate scientific description of the Laguna de Bay water system (catchment and lake).

As part of WQM, lake and river water quality are monitored continuously through thirty six (36) stations located in the rivers of Marikina, Bagumbayan, Mangangati, Tunasan, San Pedro, Biñan, Sta. Rosa, Cabuyao, San Cristobal, San Juan, Los Baños, Bay, Pila, Sta. Cruz, Pagsanjan, Pangil, Siniloan, Sta. Maria, Jala-jala, Pililla, Tanay, Baras, Taytay Barkadahan and Morong, and also in Sapang Baho and the Buli Creek.

Green Building[edit]

Inside of LLDA's Green Building.jpg
Front of LLDA's Green Building.jpg

Quezon City, is the first Philippine government structure to be accredited as a Green Building. LLDA is leading by example and is at the forefront of the green building revolution. The ‘Green Building’ is designed to be climate smart and energy efficient and services as inspiration for sustainable building practices.

The LLDA building, which enables at least 20 percent reduction in energy consumption, is the first-ever Philippine government structure to be accredited as a Green Building by the Building Ecologically Responsible Design and Excellence (BERDE) for the government and private sector.

The four-storey structure is designed with shallow building width to maximize natural daylight and with windows that allow natural ventilation, thus reducing the consumption of electricity. The rainwater catchment system provides water for flushing in water closets and urinals to conserve water.

Another feature of the building is a constructed wetland which would act as a small-scale representation of the processes that occur in the Laguna Lake. It provides for an on-site natural treatment of storm water and for cooling hot air. Pocket gardens on every floor and on the roof deck serve as ‘green spaces’ and natural filters.

The LLDA building is also home to a materials recovery facility to properly practice waste management within the complex.
