Stormwater Testing

AMSD also offers storm water testing using the Guelph Permeometer, an approved method that is more accurate and efficient than the double ring method that is often used.

On-Lot Sewage Disposal

Providing options and exceeding minimum requirements.

Allen W. Madeira started his career as a draftsman. He also quickly obtained his Sewage Enforcement Officer’s license (No. 02371, issued February 28,1991) and began working for various municipalities in Berks, Lancaster and Schuylkill Counties. As such, he has over 30 years’ experience specifically in the field of septic system design and consulting.

Currently serving clients in Berks, Schuylkill and surrounding counties, Allen no longer serves as a municipal SEO, thereby eliminating any conflict of interest with municipal service. AM Septic Design LLC can legally consult and design on-lot sewage disposal systems anywhere within the Commonwealth of Pennsylvania without conflict.

Am Septic Design LLC can help with residential as well as non-residential projects such as churches, commercial projects and others. There are many technologies for use in sewage disposal available to us today, many of which have components that can be mixed and matched, and all of which have various regulatory restrictions and uses (it’s not so simple as a choice between in-ground or sand mound!). Understanding of State and Local regulations means AMSD can offer options that clients may not have known were available to them. The goal is to find the best options for the client and not to merely meet minimum requirements!

Working without the representation of a quality consultant is like going to court without a lawyer! Understanding the intricacies of on-lot sewage disposal positions AMSD as a trusted partner for all sewage disposal needs.
