PROJECT PROFILE<br />
• The <strong>Project</strong> is a multi-purpose water supply<br />
and power project;<br />
• The second major source of water for Metro<br />
Manila, after Angat <strong>Dam</strong>.<br />
• Provides 1,900 MLD of water & 25 MW power.<br />
• A 113-meter high dam on <strong>the</strong> Kaliwa River in<br />
Tanay, Rizal.<br />
• Situated east of Metro Manila on a<br />
mountainous watershed of about 28,000<br />
hectares in <strong>the</strong> Sierra Madre Mountains.

The <strong>Project</strong>:<br />
• 1,900 MLD additional supply<br />
• <strong>Dam</strong> height: 113M<br />
• Affected Families: 4,413<br />
• <strong>Project</strong> cost – P 48B
MAJOR WORKS UNDERTAKEN<br />
• FS and detailed engineering for <strong>the</strong> <strong>Project</strong> were already<br />
completed in 1980’s including <strong>the</strong> construction of <strong>the</strong><br />
diversion tunnels<br />
• Some of <strong>the</strong> affected families were already compensated of<br />
<strong>the</strong>ir above-ground improvements and several titled<br />
properties have also been acquired<br />
• The <strong>Project</strong> including <strong>the</strong> supposed relocation was<br />
deferred in 1989 in lieu of an equally important projects,<br />
<strong>the</strong> Angat Water Supply Optimization <strong>Project</strong> (AWSOP)<br />
and <strong>the</strong> Umiray-Angat Transbasin <strong>Project</strong> (UATP)<br />
• Several reviews & updating were conducted to prepare <strong>the</strong><br />
<strong>Project</strong> for tendering and eventually for funding ei<strong>the</strong>r<br />
thru Build-Operate-Transfer (BOT) or o<strong>the</strong>r financing<br />
scheme.
ENVIRONMENTAL CONDITION<br />
• Kaliwa watershed area<br />
is 28,000 has., of<br />
which 70% is in Tanay
ENVIRONMENTAL CONDITION<br />
THE VALLEY OF LENATIN RIVER,<br />
WHICH FORMS THE WESTERN SIDE<br />
OF THE CATCHMENT, IS<br />
CHARACTERIZED BY SPARSE<br />

BUSHES AND SCATTERED TREES.<br />
LIMUTAN WATERSHED HAS<br />
MODERATE TO INTENSIVE<br />
FOREST COVER AND VIRTUALLY<br />
INACCESSIBLE
ENVIRONMENTAL CONDITION<br />
• Reduction of forest cover due to small scale<br />
logging, grazing and kaingin have continued in<br />
various parts of <strong>the</strong> catchment basin<br />
• Population has increased and new houses and<br />
government structures are existing and being<br />
built within <strong>the</strong> watershed<br />

Mitigating Measures on<br />
Environmental Impacts:<br />
• Organize a Multi-Partite Monitoring Team<br />
(MMT) that will monitor progress of work<br />
and compliance with ECC and<br />
Environmental Management Plan<br />
• Allocate an Environmental Guarantee Fund<br />
• Implementation of a Watershed<br />
Management Plan with active participation<br />
of <strong>the</strong> local communities

Current Status (as of 15 June 2008)<br />
• Since this <strong>Project</strong> was cancelled under <strong>the</strong> China Loan, <strong>MWSS</strong> is<br />
now pursuing o<strong>the</strong>r mode of procurement ei<strong>the</strong>r solicited or<br />
unsolicited proposals. In fact, Memoranda of Understanding<br />
(MOUs) were already signed by <strong>MWSS</strong> with several interested<br />
proponents for <strong>the</strong> conduct of due diligence on <strong>the</strong> <strong>Project</strong>. At<br />
present, an American firm, CalEnergy International, is presently<br />
doing due diligence and soon to submit its proposal.<br />
• Meantime, <strong>the</strong> following pre-construction activities is in progress:<br />
- Processing of <strong>the</strong> new ECC of <strong>the</strong> <strong>Project</strong>;<br />
- Processing of <strong>the</strong> Free and Prior Inform Consent (FPIC)<br />
clearance from <strong>the</strong> National Commission on Indigenous People<br />
(NCIP); and<br />
- Continuing dialogue/meeting with <strong>the</strong> LGU particularly <strong>the</strong><br />
municipality of Tanay, Rizal and <strong>the</strong> affected barangays relative<br />
to <strong>the</strong> LGU’s endorsement of <strong>the</strong> <strong>Project</strong>.
