Terra Firma trafficable, composite Water Meter Box Covers are the ideal solution for utility pits. Because they are often located near intersections or delivery zones, old concrete water meter pit access covers are notorious for breakages. Available in water meter, fire hydrant or gas valve options. Terra Firma polymer composite, heavy-duty covers and frames offer a reliable, safe, durable alternative to easily damaged concrete and metal pit covers.

Terra Firma Water Meter Box Covers are Radio Transparent and as a result enable signal transmission to and from pits. This feature allows remote monitoring of water assets and connection to the IoT (Internet of Things). If one of our many utility pit lid solutions doesn’t meet your needs we’ll be happy to talk about designing a product specifically for you.
