The massive, P11 billion peso, Jalaur River Multi-purpose Project in Iloilo Province, one of the biggest in all of the Philippines, will eventually bring flood control, irrigation expansion and improvements and a much-needed expanded public water supply to Iloilo City. The project brings improvements to the Sibalom River Irrigation System generally and to Tigbauan in particular. Those improvements are already underway. An irrigation system in Barangay Namocon had fallen into disrepair, but is now being renovated and expanded to allow increased agricultural production in fields which were unproductive due to lack of irrigation. Since more rice production in the Philippines is a key Philippine government objective,Tigbauan will be able to play a role in this bigger priority.
The Sibalom River Irrigation System originates at a dam on the Sibalom River dam just south of Leon and directs irrigation water to agricultural lands in Tigbauan. Below are a few photos of the system in Barangays Bitas, Bagumbayan and Namocan.

These viaducts bring water from Leon to Tigbauan.
As you can see in this photo, the system begins to show lack of maintenance.
At this point in Barangay Namocon, the system seems more or less defunct.
Photo from the same point as the previous photo shows renovation work underway (April 2013). When complete, the water may allow the surrounding fields to be more productive.
