Catch basins are essential in drainage systems, preventing flooding by collecting runoff water and debris. In this blog post, you will learn about the latest catch basin price list in the Philippines for the year 2024. At the same time, you will learn first about the use and importance of catch basin.
Catch Basins: Types, Uses, and Importance in Effective Drainage Systems
A catch basin is an essential component of modern drainage infrastructure, designed to efficiently manage stormwater runoff while preventing flooding and protecting water quality. These underground structures, typically rectangular or circular in shape, serve as collection points for rainwater and surface runoff before directing it into the sewer system or retention areas. In flood-prone countries like the Philippines, where heavy monsoon rains and typhoons are frequent, properly designed and maintained catch basins play a critical role in urban planning and disaster prevention.
Types of Catch Basins
Catch basins come in various materials and designs, each suited for specific applications:
Precast Concrete Catch Basins – The most durable option, commonly used in highways, commercial areas, and government projects. These heavy-duty basins can withstand vehicle loads and harsh weather conditions.
Plastic (Polyethylene) Catch Basins – Lightweight and corrosion-resistant, ideal for residential areas, parking lots, and locations where chemical resistance is important. They’re easier to install but have lower load-bearing capacity.
Fiberglass Catch Basins – Used in specialized applications where extreme chemical resistance is needed, such as industrial sites or areas with acidic runoff.
Metal Catch Basins – Typically made of galvanized iron or stainless steel, these are often used as grates or covers for concrete basins in high-traffic areas.
Key Functions and Uses
Catch basins serve multiple important functions in urban drainage systems:
Flood Prevention: By quickly collecting and redirecting stormwater, they prevent water accumulation on roads and properties.
Debris Collection: Built-in sediment traps capture leaves, trash, and other solids before they enter and clog the drainage pipes.

Erosion Control: They help manage water flow to prevent soil erosion in construction sites and natural areas.
Pollution Reduction: Advanced models include oil-water separators to filter contaminants from runoff before it enters waterways.
Infrastructure Protection: Proper drainage extends the lifespan of roads and buildings by preventing water damage to foundations.
Why Catch Basins Are Crucial in the Philippines
The Philippine climate makes effective drainage systems particularly important. With an average of 20 typhoons annually and frequent heavy rainfall, properly functioning catch basins:
Reduce urban flooding in cities like Manila, where inadequate drainage often leads to waist-deep floodwaters
Prevent road damage that costs millions in annual repairs
Help maintain cleaner waterways by filtering out trash and sediment
Are required by DPWH standards for all major construction projects
Support climate change adaptation in flood-prone communities
Maintenance Considerations
To remain effective, catch basins require regular:
Cleaning to remove accumulated sediment and debris
Inspection of grates and structural integrity
Repair of any cracks or damage to prevent collapse
Monitoring for proper water flow, especially before rainy seasons
Factors Affecting Catch Basin Prices
Material Type – Plastic (polyethylene) is cheaper than precast concrete or stainless steel.
Size & Thickness – Larger and reinforced units cost more.
Supplier & Location – Prices vary between Metro Manila and provincial suppliers.
Labor & Installation – Additional costs apply for excavation and setup.

When using the Catch Basin Price List 2024 for budgeting or procurement, it’s important to understand what is included, excluded, and what factors may affect the final cost. Below is a detailed breakdown:
1. Inclusions in the Unit Price
The prices provided in the table generally include:
✅ Base Material Cost – The price of the catch basin itself (precast concrete, plastic, metal, etc.).
✅ Standard Size & Design – Prices are based on common dimensions (e.g., 600x600mm for concrete, 500x500mm for plastic).
✅ Basic Grate/Cover – Some suppliers include a standard galvanized iron (GI) or plastic grate.
✅ VAT (12%) – Most commercial prices already include VAT unless stated otherwise.
2. Exclusions from the Unit Price
The listed prices do not automatically include:
❌ Delivery Fees – Transportation costs depend on distance and supplier policies.
❌ Installation Labor – Unless specified (e.g., “Labor & Materials”), excavation and setup are separate.
❌ Custom Designs – Non-standard sizes, reinforced structures, or special coatings cost extra.
❌ Permits & Site Preparation – Government fees, excavation, and backfilling are not included.
❌ Additional Accessories – Pipes, connectors, or sediment traps may be priced separately.
3. Key Considerations When Budgeting
A. Material-Specific Factors
Precast Concrete – Prices vary based on thickness (e.g., 4″ vs. 6″ walls) and reinforcement.
Plastic (HDPE/PP) – Lightweight and cheaper but may not be suitable for heavy traffic areas.
Metal Grates (GI, Ductile Iron, Stainless Steel) – Durability affects cost (stainless steel is premium).
B. Project-Specific Adjustments
Location – Prices in Metro Manila may be higher than in provinces due to logistics.
Volume Discounts – Bulk purchases (e.g., 10+ units) often get 5–15% discounts.
Supplier Markup – Hardware stores may charge more than direct manufacturers.
C. Hidden Costs to Watch For
Excavation & Backfilling – If the site requires deep digging, labor costs increase.
Drainage Pipe Connections – PVC/HDPE pipes linked to the basin are usually sold per meter.
Custom Engineering – For specialized projects (e.g., highways), DPWH-approved designs cost more.
4. Tips for Accurate Cost Estimation
Request Detailed Quotes – Ask suppliers for a breakdown (material, delivery, installation).
Compare DPWH vs. Private Suppliers – Government projects follow DPWH standard costs, which may differ from retail.
Check Warranty – Some premium materials (e.g., ductile iron) come with longer warranties.
Final Reminder
The prices in the table serve as a general reference (Q2 2024). For precise budgeting:
Contact suppliers directly for updated rates.
Visit physical stores (e.g., Wilcon, CWC) to inspect quality before purchasing.
