Tennis CourtDrainage Solutions
Get back in play faster with drainage systems designed for tennis courts. Low-profile perimeter drains for hard courts, sub-surface solutions for clay, and safe designs that protect players.
Tennis Court Drainage Challenges
Tennis courts demand drainage that clears water quickly while maintaining player safety and court aesthetics.
Rapid Surface Clearing
Tennis requires dry playing surfaces for safety and ball performance. Even small puddles affect play. Drainage must clear water quickly so matches can resume shortly after rain stops.
Player Safety
Drains near playing areas must be flush-mounted with no trip hazards. Grate patterns must prevent shoe or ankle entrapment. Smooth transitions between court surface and drain are essential.
UV and Weather Exposure
Outdoor courts expose drainage components to intense UV radiation, temperature extremes, and freeze-thaw cycles. Materials must resist degradation over 20+ years of exposure.
Aesthetic Integration
Premium tennis facilities demand drains that complement court aesthetics. Low-profile designs and color-matched grates maintain the clean visual appearance expected at clubs and resorts.
Tennis Court Drainage by Area
Each zone of a tennis court facility has specific drainage requirements. Proper zoning ensures rapid water removal and player safety.
Perimeter (Baseline & Sideline)
Flush-mount channel drain, 3-6 ft from baselines, heel-safe grates, Class A-B rating
Primary drainage location. Receives sheet flow from court surface. Keep outside playing lines.
Recommended Products:
Court Surface (Hard Courts)
1% minimum slope, sealed acrylic surface, no low spots, proper crown or linear grade
No drains on playing surface. Entire court slopes to perimeter. Precision grading critical.
Recommended Products:
Sub-Surface (Clay Courts)
Perforated pipe network, gravel drainage layer, geotextile separation
Water percolates through clay into drainage layer. Maintains consistent moisture for play.
Recommended Products:
Walkways & Viewing Areas
Trench drains at low points, slip-resistant grates, accessible design
Spectator areas need drainage too. ADA-compliant grates for accessibility.
Recommended Products:
Fence Line & Site Perimeter
Collect runoff from courts and surroundings, connect to storm system
Final collection point before discharge. Size for total court area drainage.

Specifications may vary by model. Consult manufacturer documentation for exact specifications. Load ratings require proper installation with concrete encasement per manufacturer guidelines.
Key Installation Considerations
Tennis court drainage requires precision grading and careful drain placement for optimal performance and safety.
Court Slope Design
Maintain 1% slope (1/8" per foot) in one direction - either end-to-end or side-to-side. Avoid compound slopes that create low spots. Laser-level during construction for precision.
Drain Placement
Position channel drains 3-6 feet outside baselines and sidelines to keep them away from player movement. Drains along the fence line work well. Ensure no interference with net posts or fixtures.
Flush-Mount Installation
Drain grates must be flush with or slightly below the surrounding surface. Raised edges create trip hazards. Use adjustable frames to achieve precise height during installation.
Material Selection
Choose UV-stable polymer or polymer concrete for outdoor durability. Stainless steel grates offer premium aesthetics. Avoid materials that become brittle in freeze-thaw conditions.
Discharge Connections
Connect court drains to the site storm system with properly sized pipes. Avoid undersizing - a single tennis court can generate significant runoff. Include cleanout access.
Clay Court Sub-Surface
For clay courts, install a gravel drainage layer 6-12" deep with perforated pipes at 15-20 ft spacing. Cover with geotextile to prevent clay migration. This layer maintains proper moisture balance.

Tennis Court Drainage FAQ
Common questions about drainage systems for tennis courts and racquet facilities.
Hard courts (asphalt or concrete with acrylic coating) use perimeter channel drains positioned just outside the playing lines. These drains should be flush-mounted with no-trip transitions. NDS Spee-D Channel and ACO Slim Channel are popular choices. The court surface slopes 1% minimum toward the drain for rapid water removal.
Clay courts require both surface and sub-surface drainage. The playing surface itself is permeable, so water percolates through the clay into a sub-surface drainage layer. This layer typically consists of gravel over perforated pipes. Surface grading prevents puddles. The porous nature means clay courts can often play through light rain.
Tennis courts should slope at 1% (1/8" per foot) minimum, typically in one direction end-to-end or side-to-side. A 1% slope is enough for drainage while not affecting play. The slope should direct water toward the perimeter where channel drains collect it. USTA and ITF standards specify acceptable slope ranges.
Drains should be positioned outside the marked playing lines, typically at the fence line or just inside the fence. This keeps drains away from player movement areas and prevents any interference with play. A 3-6 foot margin between baseline and drain is common. Court lighting and fence posts should not obstruct drain access.
Heel-safe grates with narrow slots (under 1/4") are required for player safety. The grate should be flush or recessed slightly below the surrounding surface. Polymer or stainless steel grates resist weathering. Avoid raised edges that could cause tripping. Decorative patterns that complement court aesthetics are available.
Indoor tennis courts need drainage for cleaning and occasional moisture control. Perimeter drains around the court connect to floor drains in walkways. Dehumidification systems manage air moisture. Condensation on cold surfaces may require drainage provision. HVAC and drainage systems should be coordinated.
Yes, but verify load ratings. Most maintenance equipment (sweepers, rollers, water trucks) requires Class B (10,000 lbs) minimum. Larger equipment may need Class C. Polymer grates typically handle light maintenance traffic. Ductile iron provides higher load capacity for heavy equipment or service vehicle access.
Puddles result from low spots, inadequate slope, or blocked drains. Laser leveling during construction prevents low spots. Proper 1% slope ensures sheet flow to drains. Regular drain cleaning prevents blockage. Resurfacing with slope correction may be needed for older courts. Adding spot drains at persistent puddle locations is sometimes necessary.
