House Bill 12-1126
CPOW worked with key stakeholders and the Colorado Department of Public Health and the Environment (CDPHE) to address the key recommendations of the ISDS Steering Committee which was established in 2002 by CDPHE. In addition to the Steering Committee’s key recommendations, CPOW tried to introduce a bill in 2011 that reflected our understanding of the common ground recommendations of the 2009 CDPHE onsite wastewater stakeholder process and experienced onsite wastewater professionals from across the country. While not successful, CPOW introduced a bill in the 2012 Colorado Legislative Session that was successful.
House Bill 12-1126 to update the State Statute on Onsite Wastewater Treatment Systems
On-site Wastewater Treatment Systems Regulation 43
Regulation 43 was adopted by The Colorado Department of Public Health and Environment (CDPHE) on May 13, 2013 and became effective June 30, 2013. Local boards of health were required to implement new regulations that comply with Regulation 43 for on-site wastewater treatment systems <2,000 gallons per day by June 30, 2014.
Please see the CDPHE website for additional information.
Regulation 43 can be found here.
Non-Pressurized Drip Dispersal System (NDDS)
The NDDS system is recognized as a type of an Evapotranspiration/Absorption system and is therefore accepted as a proper means of effluent dispersal as long as the CPOW design document is followed. Further note that the September 2016 CPOW NDDS document will be referenced in the proposed revisions to Regulation 43 as a type of an Evapotranspiration/Absorption system. Therefore, all future designs which propose an NDDS as a means of effluent dispersal must be designed in accordance with this updated document.
