ISDS 



**Prohibit use of septic system cleaners of any type in areas within the 

 recharge zones of sensitive phosphorus-limited waterbodies subject to 

 eutrophication. 



**Prohibit use of septic system cleaners of any type on substandard lots 

 having insufficient alternative area to install an adequate replacement 

 system. 



EDUCATION 



Many engineers, contractors, surveyors, drain-layers, sanitarians, ISDS installers, 

 waste haulers, building inspectors, and other town and state officials, as well as the public 

 clients they serve, are insufficiently informed regarding the purpose of site evaluation, and 

 the critical roles which proper design, installation, and maintenance of ISDS play in 

 preserving the consumer's investment, protecting public health and preventing water 

 quality degradation. 



Recommendations 



*A policy evaluation manual describing waste water management issues 

 should be prepared for town and state officials and the Rhode Island 

 courts. The publication should reference available documentation regarding the inter- 

 relationship between growth management and effective watershed management The 

 handbook should address the need for protection of water supply aquifers and other natural 

 resources, the pervasive impacts which improperly treated sewage effluent can create 

 across property lines and jurisdictional boundaries, the costs and benefits which both ISDS 

 and community sewers present, and other issues of concern. 



*A training handbook describing principles of ISDS function, potential 

 water quality impacts, and the basics of ISDS protection and maintenance 

 should be prepared. The handbook should be distributed to all applicants for ISDS 

 permits, to towns for distribution to homeowners, and to the general public. (Maintenance 

 recommendations currentiy specified in the CRMP Red Book are itemized in the following 

 section.) 



**A technical training manual should be prepared for DEM staff, designers, 

 installers, contracting professionals, building inspectors, and state and 

 town officials . The handbook should describe the basis and rationale of site 

 evaluation, the principles of ISDS function, issues of concern in installation and 

 maintenance, and potential water quality impacts of failed systems.
