Umiray River is the river that separates Aurora and Quezon provinces. It is bounded by the towns of Dingalan in Aurora and General Nakar in Quezon.

It is used as a means of transport by the illegal loggers. [1] From the mountains, the illegal loggers float the troso (lumber) and float them downstream up to the ocean. During the late 20th century (and continuing up to the present), it has been the site of several clashes between the army and the communist group, the New People's Army. In 1995, the government has made a project called Umiray–Angat Transbasin Project (UATP) to link the Pacific Ocean with Angat River in Bulacan's mountains through a tunnel that will traverse Umiray River then cut through the mountains of Sierra Madre straight to Angat River. In 2013, the Manila Water and Sewerage System signed an agreement with the General Nakar, Quezon local government unit to replace the structures made in 1995 to increase the flow from the Umiray to the Angat.

<span class="mw-page-title-main">Angat Dam</span> Dam in Bulacan, Philippines

Angat Dam is a concrete water reservoir embankment hydroelectric dam that supplies Metro Manila and nearby provinces with water. It was a part of the Angat-Ipo-La Mesa water system. The reservoir supplies about 90 percent of raw water requirements for Metro Manila through the facilities of the Metropolitan Waterworks and Sewerage System and it irrigates about 28,000 hectares of farmland in the provinces of Bulacan and Pampanga.

Several bulk water supply projects on the upper portion of the Kaliwa River Watershed have been proposed by the Philippine Government since the 1970s, with the intent of relieving Metro Manila of its overdependence on the water supplied by Angat Dam. Most of these have focused on a particular site in Barangay Laiban in Tanay, Rizal, on the upper portion of the Kaliwa River Watershed to which the Laiban Dam belongs, and the projects have thus often been referred to as Laiban dam or Kaliwa dam, although multiple projects have been referred to using either name.

<span class="mw-page-title-main">Sierra Madre (Philippines)</span> Mountain range in the Philippines

The Sierra Madre is the longest mountain range in the Philippines. Spanning over 540 kilometers (340 mi), it runs from the province of Cagayan down to the province of Quezon, forming a north–south direction on the eastern portion of Luzon, the largest island of the archipelago. It is bordered by the Pacific Ocean to the east, Cagayan Valley to the northwest, Central Luzon to the midwest, and Calabarzon to the southwest. Some communities east of the mountain range, along the coast, are less developed and so remote that they could only be accessed by taking a plane or a boat.

<span class="mw-page-title-main">Angat Watershed Forest Reserve</span>

The Angat Watershed Forest Reserve is a conservation area that protects the drainage basin in the southern Sierra Madre range north of Metro Manila in the Philippines where surface water empties into the Angat River and its distributaries. It is spread over an area of 62,309 hectares in the eastern portion of Bulacan and northern Rizal province at an altitude of between 490 and 1,206 metres. The conservation area also extends to the provinces of Nueva Ecija and Quezon and is centered on an artificial lake created by the Angat Dam which, together with the Ipo Dam located 7.5 kilometres (4.7 mi) downstream, supply 97% of the water requirement of Metro Manila via an aqueduct system to the La Mesa Dam and Reservoir and the Balara Filtration Plant in Quezon City. The Angat Dam and Reservoir is also a major source of hydroelectricity for Metro Manila and surrounding provinces, contributing some 200 megawatts to the Luzon grid. The watershed is a popular birdwatching site and is a biodiversity hotspot containing most of the remaining closed-canopy forests in Central Luzon.

The Umiray–Angat Transbasin Project (UATP) is an expansion project of the Metropolitan Waterworks and Sewerage System (MWSS) for the supply of the Angat Dam reservoir. The 13-kilometer-long (8.1 mi) 4.30-meter (14.1 ft) diameter tunnel-aqueduct system diverts waters from the Umiray River east of the Angat Basin. 20–30% of the water that is consumed in Metro Manila and its outlying regions is supplied by the Umiray Basin.

The Sumag River Diversion Project (SRDP) is an expansion project of the Umiray-Angat Transbasin Project (UATP) Metropolitan Waterworks and Sewerage System (MWSS) for the supply of the Angat Dam reservoir. The 600 meter long and 2.50 meter diameter tunnel-aqueduct system diverts waters from the Sumag River, a tributary of the Umiray River, east of the Angat Basin. The SRDP is forecasted to add 188 mld to the existing 777.6 mld capacity of the UATP.
