Product OverviewRecommended load ≤5T, capable of bearing pedestrians and small maintenance tools, well-matching the operation needs of small water meter wells and local drainage needs of narrow roads;
The small rectangular drainage hole design fits the limited space of narrow roads, helping quickly drain local water around water meter wells while facilitating maintenance of small water meters.
SMC composite material has strong erosion resistance in the humid environment of small water meter wells, with an expected service life of over 18 years under proper use;
The surface material is 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 small water grate & water meter covers to some extent;
Integrates water grate drainage and water meter inspection functions, eliminating the need for additional small drainage facilities and simplifying supporting costs for small scenarios.
Weighing about 12kg (vs. ~25kg for the same-sized cast-iron product), it can be easily installed/maintained by a single person, greatly reducing labor input for small water meter well operation.

Clean debris from the small 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 road), 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 small water grate products have passed relevant certifications for municipal micro facility materials;
Supports customization of micro sizes and drainage hole layouts to meet different micro water meter well scenario needs;
Door-to-door delivery is available for bulk orders, with supporting installation guidance for micro scenarios.
