Norzagaray, officially the Municipality of Norzagaray, is a 1st class municipality in the province of Bulacan, Philippines. According to the 2020 census, it has a population of 136,064 people.
The La Mesa Dam and Reservoir is an earth dam in Quezon City, Philippines. Its reservoir can hold up to 50.5 million cubic meters, occupying an area of 27 square kilometers (10 sq mi). It is part of the Angat-Ipo-La Mesa water system, which supplies most of the water supply of Metro Manila.
The Philippines' water supply system dates back to 1946, after the country declared independence. Government agencies, local institutions, non-government organizations, and other corporations are primarily in charge of the operation and administration of water supply and sanitation in the country.
Water privatization in Metro Manila began when the then President of the Philippines, Fidel Ramos, instructed the government in 1994 to solve what he called the water crisis in Manila by engaging with the private sector. In 1997, two concession contracts for the Eastern and Western halves of Metro Manila were awarded after an open competition. The concessions represent the largest population served by private operators in the developing world. Both winning companies, Maynilad Water Services in West Manila and especially Manila Water in East Manila, submitted bids with extremely low water tariffs. The tariffs proved to be too low to finance the investments needed to improve performance, especially after the East Asian financial crisis and the devaluation of the Philippine Peso.
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.
In Russia, approximately 70 per cent of drinking water comes from surface water and 30 per cent from groundwater. In 2004, water supply systems had a total capacity of 90 million cubic metres a day. The average residential water use was 248 litres per capita per day. One quarter of the world's fresh surface and groundwater is located in Russia. The water utilities sector is one of the largest industries in Russia serving the entire Russian population.
Water supply and sanitation in Turkey is characterized by achievements and challenges. Over the past decades access to drinking water has become almost universal and access to adequate sanitation has also increased substantially. Autonomous utilities have been created in the 16 metropolitan cities of Turkey and cost recovery has been increased, thus providing the basis for the sustainability of service provision. Intermittent supply, which was common in many cities, has become less frequent. In 2004, 61% of the wastewater collected through sewers was being treated. In 2020 77% of water was used by agriculture, 10% by households and the rest by industry.
Water supply and sanitation in Malaysia is characterised by numerous achievements, as well as some challenges. Universal access to water supply at affordable tariffs is a substantial achievement. The government has also shown a commitment to make the sector more efficient, to create a sustainable funding mechanism and to improve the customer orientation of service providers through sector reforms enacted in 2006. The reform creates a modern institutional structure for the water sector, including an autonomous regulatory agency, an asset management company and commercialised state water companies that have to reach certain key performance indicators that will be monitored by the regulatory agency. The government has also stated its intention not to embark on new private sector contracts for water provision, after a bout of such contracts during the 1990s showed mixed results.
Water supply and sanitation in Japan is characterized by numerous achievements and some challenges. The country has achieved universal access to water supply and sanitation; has one of the lowest levels of water distribution losses in the world; regularly exceeds its own strict standards for the quality of drinking water and treated waste water; uses an effective national system of performance benchmarking for water and sanitation utilities; makes extensive use of both advanced and appropriate technologies such as the jōkasō on-site sanitation system; and has pioneered the payment for ecosystem services before the term was even coined internationally. Some of the challenges are a decreasing population, declining investment, fiscal constraints, ageing facilities, an ageing workforce, a fragmentation of service provision among thousands of municipal utilities, and the vulnerability of parts of the country to droughts that are expected to become more frequent due to climate change.
The Metropolitan Waterworks and Sewerage System, formerly known as the National Waterworks and Sewerage System Authority (NAWASA), is the government agency that is in charge of water privatization in Metro Manila in the Philippines. It split the water concession into an east and a west concession with Manila Water being awarded one contract and Maynilad Water Services being awarded the other.
Maynilad Water Services, Inc., better known as Maynilad, is the water and wastewater services provider of cities and municipalities that form the West Zone of the Greater Manila Area in the Philippines. It is an agent and contractor of the Metropolitan Waterworks and Sewerage System (MWSS). Maynilad is one of two private water providers in Metro Manila, the other being Manila Water.
The Kaliwa Low Dam, proposed by the Philippine Government in 2012, was one of several bulk water supply projects on the upper portion of the Kaliwa River Watershed that have been proposed but ultimately shelved by the Philippine Government since the 1970s.
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.
Carriedo Fountain is a fountain in Santa Cruz, Manila, Philippines. It was built in honor of the 18th-century Capitán General of Manila, Don Francisco Carriedo y Peredo, benefactor of Manila's pipe water system. It was moved three times before its current location at Plaza Santa Cruz, right in front of the Santa Cruz Church.
Water supply and sanitation in Georgia is characterized by achievements and challenges. Among the achievements is the improvement of water services in the capital Tbilisi where the water supply is now continuous and of good quality, major improvements in the country's third-largest city Batumi on the Black Sea where the country's first modern wastewater treatment plant now is under operation, as well as a general increase in access to drinking water in the entire country. Water and sewer tariffs remain affordable, with the private water company Georgian Water and Power (GWP) serving the capital being financially viable and profitable, while the public water company serving most of the rest of the country remains financially weak. The improvements were achieved after the Rose Revolution of 2004 when the government decided to reform the sector and to invest in it after many years of neglect.
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 water crisis in Metro Manila, Philippines is the ongoing crisis that affected most of the households with a water interruption. The crisis usually occurs in dry season from March to May. The water suppliers, Manila Water and Maynilad, held responsibility for the crisis.
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.
