Product OverviewRecommended load ≤3T, capable of bearing pedestrians and mini water meter maintenance tools, well-matching the dual needs of ultra-small water meter well operation and narrow-area drainage;
The ultra-small long-strip drainage hole design fits extremely small spaces, which can quickly drain trace water around the water meter well while reserving just enough operating space for mini water meter maintenance.
SMC composite material has decent erosion resistance in the humid environment of ultra-small water meter wells, with an expected service life of over 18 years under proper use;
The ultra-small drainage holes + dense surface material are not easy to adhere to fine dust and sludge, making daily cleaning and maintenance relatively convenient.
Non-metallic material has no recycling value, which can alleviate the theft issue of traditional cast-iron ultra-mini water grate & water meter covers to some extent;
Integrates water grate drainage and water meter inspection functions, eliminating the need for additional narrow drainage facilities and simplifying supporting costs for extremely small scenarios.
Weighing about 8kg (vs. ~15kg for the same-sized cast-iron product), it can be easily installed/opened/closed by a single person, reducing labor input for ultra-small water meter well operation.

Clean debris from the extremely small water meter well opening and confirm the precise compatibility of the support frame with the opening;
Align the drainage holes (preferably toward the water accumulation side of the narrow area), lay the cover, and fasten the buckles;
Conduct a light pressure test to confirm the cover’s stable fit.
Clean fine dust and debris from drainage holes every 3 weeks to keep drainage unobstructed;
Inspect buckle firmness every 6 months (focused verification is recommended after the rainy season);
No additional anti-corrosion treatment is required. If damaged, send an email to jschangan111@gmail.com to contact the manufacturer for replacement coordination.
With over 10 years of experience in composite manhole cover production, its ultra-mini water grate & water meter covers have passed relevant certifications for municipal ultra-mini facility materials;
Supports customization of ultra-mini sizes, drainage hole layouts, and logos to meet different extremely small water meter well scenario needs;
Delivery service is available for bulk orders, with exclusive installation guidance for ultra-mini projects.
