Operational
water districts.
There
are 66 operational water districts in Region 4 currently serving
over 2 million people in 76 towns of the region's 212 cities and
municipalities. The average water district collection efficiency
in Area 3 is 86 percent, while the average non-revenue water stands
at 28.8 per cent.
WD
Organizations. The Southern Tagalog Water Information Council
(SOTWIC) which was formed jointly by LWUA and the water district
general managers in Region IV during the early 80s was the first
organization in the area. A decade after, SOTWIC changed in character
with the addition of the board of directors of the water districts
to the roster of its membership and metamorphosed to become the
Southern Tagalog Association of Water Districts (STAWD) in the
90s. Today it is considered as the umbrella organization of all
the water districts in Region IV.
There
are also provincial organizations of water districts in the region
namely: CAWAD or Cavite Association of Water Districts, LAWD or
Laguna Association of Water Districts, BAWAD or Batangas Association
of Water Districts and, RIZWADA or Rizal Association of Water
Districts.
As
in other regions, water districts in the area have acknowledged
leaders or so-called Godfather Water Districts. These are: Dasmariñas
Water District for Cavite; San Pablo City Water District for Laguna;
Metro Lipa and Batangas City Water Districts for Batangas; Quezon
Metro Water District for Quezon, and Puerto Princesa City Water
District for Palawan.
Water
Sources.
Water resources potential evaluated for both surface water and
groundwater in Region IV is high. The area is relatively rich
in water resources in terms of total endowments. However, their
seasonal variations are large and geographic distribution is biased.
There are extensive areas where extended dry periods are observed
every year. Most river basins in the region are small with limited
impoundment areas and capacity.
Groundwater
availability is relatively high, but most promising groundwater
reserves are confined largely to fluvial lowlands along the lakeshore
of Laguna de Bay and limited areas along the coasts.
Another
notable characteristic is the existence of the much-utilized Laguna
de Bay and the largely unutilized Taal Lake. Lands in Region IV
are extensively covered by volcanic ashes, which make them vulnerable
to erosion.
For
almost all the existing piped systems, groundwater (shallow well
and deepwell) is utilized as the water source in the provinces
of Cavite, Laguna, Rizal, Batangas, Rizal, Mindoro, Palawan, and
Romblon.
Other
water districts located near Mt. Banahaw in Quezon and Mt. Makiling
in Laguna draw their water supply from mountain springs.
