BusinessWorld Online: The Laiban dilemma: "The Laiban dam project was conceived in the 1970s as a part of the Industrial Complex Plan in north eastern Luzon. It was deferred, however, as the project met opposition from people.
The project was later restored as a joint-venture of San Miguel Corp. and the Manila Waterworks and Sewerage System (MWSS) to address the estimated 1.6 billion liter per day water shortage in Metro Manila by 2015. In fact, the Laiban Dam is seen as an alternative water source for Metro Manila, especially during times when the Angat Dam in Bulacan becomes an unviable source of water during typhoons.
To augment water supply, the project entails the construction of a dam in Tanay, Rizal utilizing the Kaliwa River Basin, which passes through the slopes of Sierra Madre and into the Pacific shoreline on the side of Quezon.
The dam is expected to yield approximately 1.9 billion liters a day intended to serve an estimated population of about 5.5 million in and around Rizal Province. It is also estimated to generate about 25 megawatts of hydropower. The NEDA-ICC approved cost amounts to P47.93 billion, and the construction is projected to be carried out within 5 years.
The project seems promising on the surface, considering the problem of water adequacy in the Metro amidst the growing demand from its expanding population. There are, however, hurdles that the government is facing in light of this enterprise, among them protests from the public and the church.
A costly enterprise
Appeals were sent to the MWSS by certain groups, saying that the dam “is the most expensive project to be undertaken by the MWSS, in terms of economic cost, size and expanse of the infrastructure, numbers of stakeholders to be affected, environmental effects, human rights, and the challenges to the existing environmental and indigenous laws”.
Apart from the obvious pecuniary costs, the project also appears to put several areas at even greater risk. Pambansang Kilusan ng Samahang Magsasaka (Pakisama) observes that the planned 113-meter high structure poses a threat to three Quezon provinces�”Infanta, Real and Gen. Nakar�”in case it collapses.
In addition, the Freedom from Debt Coalition (FDC) has said that the area of planned reservoir is surrounded by a number of fault lines, five of which have been identified as active, including the Marikina-Infanta fault line.
The project is also said to affect around 27,800 hectares of ancestral and agricultural lands, including some 3,000 hectares of mangrove fish sanctuaries and farm irrigation systems in the towns of Gen. Nakar, Real, and Infanta. Habitats of endemic and endangered species in forested areas are likewise seen to be affected as the project rolls out.
Along with the alleged impact on the environment and the purported violations of laws such as the Environmental Impact Statement (EIS) System, the National Integrated Protected Areas System Act (NIPAS), and the Wildlife Resources Conservation and Protection Act (Wildlife Protection Act), as well as the Indigenous People’s Rights Act (IPRA), concerns on the welfare of affected families have also been put forward as one of the project’s biggest challenges.
The dam is expected to displace thousands of families, including the indigenous communities of Dumagats and Remontados. Moreover, an alleged “take-or-pay” provision contained in the contract with the San Miguel Bulk Water Company, Inc. is seen to burden the MWSS with costs should supply exceed actual demand. Advocacy groups fear that these costs may eventually be passed on to households through higher water charges.
Other options
Other options to address the water shortage have been presented amid the intense opposition and challenges.
Local firm Sierra Madre Water Corp. (SMWC) proposes a cheaper and an allegedly more environment friendly source of water. The SMWC promises a supply of 2 billion liters per day and can be operational in 24 months�”which, offhand, trumps Laiban’s capacity of 1.9 billion liters per day and expected five-year roll-out.
The company also stresses that it has smaller environmental footprints, since its dam requires smaller construction with capital costs lower than the Laiban proposal. The SMWC also assures that no more than 100 families will be affected or will need to resettle; the water will also be released towards the Pacific Ocean, so there will be less risk of flooding in the surrounding areas.
Another proposed option is the Wawa Dam in Montalban. Oscar Violago, president of San Lorenzo Ruiz Builders and Developers Group, Inc., the company that owns the rights to the Wawa River Dam project, enumerates a few of the advantages of Wawa Dam over Laiban.
The Wawa reservoir is reportedly still full, and millions of water go over the dam and flows to the sea everyday. The dam also covers about 27,700 hectares, or almost the same as Laiban’s, so Wawa’s production capacity can be expected to be at par with Laiban’s.
The Wawa Dam also requires minor renovations�”for one, it already has existing pipelines, so it doesn’t require further tunneling�”and can thus be operational again within eight months. Just as important, it is not expected to affect communities, especially ancestral and agricultural lands.
On the other hand, NGOs contend that instead of building another dam, efficiency and effective forest protection or forest conservation are just as viable solutions. Environmental groups have also emphasized that strengthening the anti-logging campaign and the restoration of existing watersheds like Angat, Ipo, La Mesa and Wawa can enhance water flow.
Furthermore, the reduction of water demand and improvement of the efficiency of water delivery systems (e.g., by minimizing leakages and non-revenue water levels) are “simple and economical options”. In a public report, both Maynilad and Manila Water declared that their losses of 69% and 20%, respectively, were mainly due to leakages.
No easy task
In economic parlance, allocative efficiency is a key consideration in evaluating projects. That is, any decision to allocate resources produces both winners and losers. The benefit principle is an oft-used maxim: a project or a policy increases or maximizes allocative efficiency�”and, therefore, must be pursued�”as long as the benefits exceed the cost.
Securing the country’s water supply is no easy task and rightfully earns its spot among the country’s priorities. The threat of shortage is real and requires speedy interventions from the government. But any proposed solution should be carefully considered and weighed against a viable alternative, if only to ensure that the end-result comes at a minimal cost.
