   Small Community’s Call to NSFC Results in Big Savings
          by Chris Berry
      NSFC Contributing Writer

   Palouse, Washington, a town with
   a population under 1,000 and a
   sewer plant constructed during the
   1950s, faced a problem. The
   Washington Department of Ecol-
   ogy had discovered the town’s
   sewage treatment plant was out of
   compliance. The town was ordered
   to correct the problem.

   The Palouse City Council was
   stunned. The prospect of financing
   a new system was staggering. To
   give the town more time, the plant      A small Washington community saved more than $3 million on its new wastewater treatment plant after consult-

   Improving the Public’s Perception of Biosolids

   Biosolids are the treated end prod-
   ucts generated during the treatment
   of sewage. In other words, they are
   the processed organic solids that




                                                                                                                                                                    biosolids
   have been separated from the liq-
   uid portion of municipal wastewa-
   ter during treatment.

   Following treatment these solids
   may be incinerated in a furnace,
   disposed of in a landfill or a desig-
   nated surface disposal site (e.g.,
   monofill), or land applied for ben-
   eficial purposes.

   Over the past 25 years, there has
   been an increasing interest in the
   land application of biosolids to
   agricultural and landscaping areas,
   in addition to using heat drying/
   pelletizing, composting, and alka-
   line stabilization processes to pro-
   duce biosolids by-products.             A truck applies biosolids to a farm in western Pennsylvania. There are approximately 1,500 permitted
                                           sites in Pennsylvania where biosolids can be applied for agricultural, land reclamation, and other pur-

   Faced with a troubled wastewater
   system and a hefty price estimate
   to address the problems, residents
   of a small Washington community
   took matters into their own hands.

   The town of Wilkeson, with just
   over 400 residents, is one of many

   Small Towns Environment Pro-
   gram (STEP).

   Wilkeson’s wastewater system
   could not meet its discharge permit
   requirements due to a failing col-

   and high ammonia levels. The
   system also lacked an alternate        Communities can dramatically reduce the costs of their wastewater system projects if residents
