�y <br /> T ff l <br /> xgnificant progress has been made during the last 30 years to improve the effluent '.. <br /> quality of municipal wastewater treatment systems.Virtually all older facilities have <br /> been significantly upgraded,and most systems constructed since the early 19705 have <br /> implemented treatment technologies that produce an effluent quality significantly higher than <br /> was the norm prior to the passage of the Clean Water Act.However,during the last 5 to 10 years, <br /> numerous systems either built or upgraded prior to 1985 have again required upgrading to meet <br /> more-stringent discharge limitations and increased loadings.In addition,many new treatment <br /> facilities have been constructed in rural communities with wastewater collection systems. '..... <br /> Most large communities have sufficient economic and technical resources to ensure that <br /> the new facility planning process adequately matches their needs with the wide range of <br /> available treatment technologies.Smaller communities however,frequently lack either the '... <br /> economic resources or technical expertise to support a facility planning process that examines <br /> the broadest range of appropriate treatment technologies.Frequently,the consultants,public <br /> works staff,and community decision-makers have training or experience with only a limited <br /> range of"conventional"treatment technologies,and the facility planning process fails to consider <br /> a wide range of potentially applicable alternative technologies.The selection of inappropriate <br /> technologies often results in facilities that perform poorly and fall into disrepair due to a lack <br /> of basic resources,such as spare parts,operations and maintenance personnel,and technical <br /> expertise. <br /> 51 <br />
