Product OverviewRecommended load ≤5T, capable of bearing pedestrians and mini water meter maintenance tools, well-matching the dual needs of mini water meter well operation and narrow-area drainage;
The small long-strip drainage hole design fits mini spaces, which can quickly drain local water around the water meter well while reserving sufficient operating space for mini water meter maintenance.
SMC composite material has decent erosion resistance in the humid environment of mini water meter wells, with an expected service life of over 18 years under proper use;
The small drainage holes + dense surface material are not easy to adhere to fine 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 mini water grate & water meter covers to some extent;
Integrates water grate drainage and water meter inspection functions, eliminating the need for additional mini drainage facilities and simplifying mini scenario supporting costs.
Weighing about 12kg (vs. ~25kg for the same-sized cast-iron product), it can be easily installed/opened/closed by a single person, reducing labor input for mini water meter well operation.

Clean debris from the mini water meter well opening and confirm the support frame’s compatibility 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 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 mini water grate & water meter covers have passed relevant certifications for municipal mini facility materials;
Supports customization of mini sizes, drainage hole layouts, and logos to meet different mini water meter well scenario needs;
Delivery service is available for bulk orders, with supporting basic installation guidance for mini projects.
