I assume your looking for a pump chamber to pump sewage ?If so I have done that please clarifiy .Each state has it's own rules a local engineering firm can design one for your needs.As far as instalation they are simpler than you might think. Some toilets have self contained pumps for elevating sewage short "lifts" between floors maybe thats what your referining to ( home depot) I hope that helps

Please see Global Spec's list for sewage pumps.

Go to Zoeller Pump Co. www.zoeller.com, They manufacturer a lot of prepackaged sewage pump stations.

As a Civil Engineer who deals with municipal sewage and water conveyance system. I would suggest you gather some basic site information (topography, facilities locations, proposed pipeline alignments, basic soils information) and contact a local civil engineer. It may be simple and not worth his time, but he can direct you to a solution locally. However, it could be quite involved in construction, design and/or permitting. You might never be able to complete the installation wihout a stamped and approved design. Your local CE should know the local mrequirements and be able to help you. FYI, Lift stations are notorious for high O&M relative to purely gravity flow systems, sometimes relocating TSD systems down gradient is a better (and more cost effective) option.

If this is for a residential property, it is unlikely that you need an engineer. I live in Ohio and engineers are only required on commercial projects or new subdivisions. Check with your local health department. It is unlikely that you need an extensive lift station. A 2HP residential grinder pump should be more than efficient. (I have one at my house) Google "Residential sewage gringer pumps" for costs and dealers in your area. Personally, I use Zoeller Pumps when designing residential properties that need these systems. They have a system that can be installed inside during construction. As stated above, O&M is always an issue when dealing with mechanics. Another option may be a siphon. Check out www.siphons.com

Just had my Zoeller replaced on a 5 yr old house. They said the pump chamber is too small (24" diameter) and the pump had been cycling too frequently in a 3 bathroom house with six residents. Does that sound right? The city sewer pipes are uphill from the house so we need the grinder pump to get it to the street.
