(10' length) This tank was manufactured by P&S concrete in North Chittenango, NY. The original style hasn't changed other than an upgrade from thin wire handles to heavy wire. Commonly used from 1980-present. Newer versions from this Mfg have three 18" round poly lids.

(10'6" length) This tank was originally manufactured by Deal's Precast in Vernon Center, NY. We've been installing this style tank from 1995-present. Although today, it's made by American Concrete in Canastota, NY

(8' length) This tank was manufactured by Sunnycrest Precast in Auburn, NY. This tank has been referred to as the "Dean Hubbs tank" due to the nearly exclusive local use by our company for many years. We installed literally hundreds of these tanks from 1978-1993

(8' length) This tank was manufactured by Sunnycrest Precast in Auburn, NY. We installed these tanks from 1993-1995. There is also a 2-compartment version that has a lid in the center as well. The outlet baffle was made of PVC and attached with stainless steel pins.

(8' length) This tank was manufactured by P&S concrete in North Chittenango, NY. Style wasn't changed for many years other than an upgrade from thin wire handles to heavy wire. Rarely used from 1980 (to around) 2000. For the last few years they've been using round green plastic riser covers.

(8' length) This tank is responsible in part for my ailing back. The manufacturer cast the baffles onto the lids! When the unsuspecting worker attempts to lift the cover, he gets about 12 inches of lift and only then does he realize the assumed 30 lb cover is actually 100 lbs! It is common for these baffles to break off (easily repaired).

(8' length) If your home was built in the 1960's and the contractor installed a concrete tank instead of metal, you probably have this tank in your lawn. The end covers come off and are VERY heavy and fragile. This one also has a 24" center cover.

(8' length) Another version of the 1960's tank is nearly identical to "style A" without the handy center cover. Styles "A and B" were both notorious for outlet baffle "rot-off" (easily repaired).

(8' length) Yet another version of the 1960's tank is nearly identical to "styles A and B" only in addition to the end covers, there are two more larger removable sections.

It should be noted that all three styles "A, B, and C" were optionally available with knock-out plugs on the inlet and/or outlet covers. Many homeowners have these broken out for use as a cleanout and some even have a pipe installed as a riser to bypass the trouble of removing the large cover. Just so you know, the smaller the opening for a cleanout, the less sludge a pumper will be able to remove. It is advisable to remove at least one large cover on any tank to get a thorough pump job.
