After serving as Vice President of an ENR 500 Consulting Engineering form, John W. Naylor, Jr., P.E. opened Naylor Engineering, P.C. in 1990.   At that point Mr. Naylor had already begun establishing the firm's reputation as the region's primary innovator in the field of wastewater treatment.  In 1985, Mr. Naylor began studying the Sequence Batch Reactor method of treatment.  At that time the SBR process  had gained popularity in Australia, Europe and even some portions of the United States but had never been used for tertiary treatment on Long Island or anywhere in the tri-state area.

This became of significance here on Long Island when updated regulations mandated the upgrade of older secondary plants to tertiary treatment.   Mr. Naylor's predecessor firms were therefore well positioned to offer an upgrade alternative which was 25 - 50% of the capital cost of recommended offerings from other firms.  In addition, this alternative lowered power costs and eliminated the costs and hazard associated with the use of hazardous chemicals.  It would be several years before other consulting firms began preparing designs based upon the SBR process which has now since become the defacto standard method of treatment for small to mid size treatment facilities (> 15,000 GPD) in the region.

Later, in the early 1990's, the region was faced with the continued failure of passive underground nitrification / denitrification systems, a solution which Naylor held to be non-viable since they were first introduced.  Because of said failures, a moratorium was placed on said systems until, eventually, they were prohibited.  Again, Naylor Engineering provided the only currently available solution.

The Cromaglass system had previously been deemed unacceptable to area regulatory agencies so Naylor worked with the manufacturer and helped redesign system components which were believed to be objectionable.  The revised design was submitted to regulatory agencies in 1993, was approved shortly thereafter and has enjoyed successful operation for a dozen years.

Again, the Cromaglass system has become the defacto standard in the region for treatment facilities receiving up to 15,000 GPD.   NEPC has since designed Cromaglass systems in three states, has served as a consultant to Cromaglass, wrote the Cromaglass System O & M Manual and most recently has licensed Naylor copyrighted designs for the commercial manufacture accessory system components for both the Cromaglass and large scale treatment facilities.
