Jensen Precast has been manufacturing and fine-tuning an entire line of traditional water storage and conveyance products since 1968. Our vaults, holding tanks, cisterns, and manholes represent a large menu of geometric shapes that are readily available, economical solutions well-suited to serve in stormwater detention and infiltration applications.
Precast tanks and manholes come in a variety of size options. Our readily available, off the shelf, precast vaults, holding tanks and manholes are ideal for project detention needs calling for 2,000 cubic feet (approximately 15,000-gallons), or less. Depending on capacity, vaults and holding tanks are available in a monolithic or battery style. For larger detention and infiltration needs, assembling tanks and vaults together in a battery system provides an economical, scaling option. Jensen Stormwater Systems can help evaluate the many available options to develop the best suited, most economical option for a development project. In addition to tanks and cisterns, we offer standard manholes with internal diameters from 4 to 12-ft. To our knowledge, we are also unique in offering the only available 16-ft internal diameter manhole in the region.
Our traditional systems have been in use for many decades and have a proven track record of performance and ease of maintenance. A variety of loading options combined with the modular application of our vaults, tanks, and manholes to detain, infiltrate, and store stormwater is a powerful, yet simple solution for design engineers to meet a project’s volumetric needs.
