First Notice version contained Green Plumbing section.

Amended the definition of lead free Exemptions include pipes, pipe fittings, plumbing fittings, or fixtures, including backflow preventers, that are used exclusively for nonpotable services, such as manufacturing, industrial processing, irrigation, outdoor watering, or any other uses where the water is not anticipated to be used for human consumption; or toilets, bidets, urinals, fill valves, flushometer valves, tub fillers, shower valves, service saddles, or water distribution main gate valves that are 2 inches in diameter or larger.

2 Changes to the Code Amended the Variance section The Department will consider variances to this Part when the applicant has provided documentation citing the particular portion of this Part for which a variance is sought and has provided justification sufficient, in the opinion of the Department, to demonstrate that the variance will not create a condition less protective than that portion of this Part addressed in the variance request. Issuance of variances to this Part is at the sole discretion of the Department and may not be delegated or assumed by any other authority identified in this Part. Variance authorizations may be conditioned as determined by the Department and are not precedential. Changes to the Code Majority of the referenced standards were updated to current version. Illustrations in the Appendix were redrawn in CAD and updated. Minor changes in pipe sizing tables were made based upon low flow fixtures 2

3 New Plumbing Related Codes Plumbers Licensing Code (Publishes 10/10/14) Requires all plumbing inspectors to be certified by IDPH Increased licensure fees Provides for better availability of the Certification Exam Contractors Registration Code (On Second Notice) Irrigation Code (On Second Notice) Justin DeWitt & Darrah Dunlap October

4 Reuse is Gaining Popularity in IL Economic benefits Environmentally sustainable Relief for overburdened combined sewer systems i.e. Chicago Public Health Considerations for Water Reuse Presence of opportunistic pathogens Presence of total coliforms (i.e. E.coli) Biofilm creation in piping and storage tanks Creation of anaerobic conditions in storage tanks Water aesthetics Adverse public health outcomes 4

5 3 Tiers of Water Reuse Tier 1 Harvested water for potable uses Drinking, full body contact Tier 2 Harvested water for uses that result in human contact i.e. spray irrigation, car washing, makeup water Tier 3 Harvested water for non-potable uses i.e. drip irrigation, subsurface IDPH Reponses to Water Reuse Currently not seeking to propose rules on water reuse Process of plan submittal to the Department, departmental review, and issuance of conditional approvals by IDPH Testing conditions determined by tiered use and proposed system specifications Tested variables are reported to IDPH each month for public health monitoring 5

6 IDPH Review To assure public health the IDPH considers many factors will reviewing rainwater harvesting systems, including: Application/use of harvested water Possible sensitivities at the system s address Treatment of harvested water prior to use The demand on the harvested water supply (avoidance of stagnant water conditions) Recent IDPH Approved Projects Storm water reuse for spray irrigation (Tier 2) System featured a large storage tank fed by overland runoff Harvesting system was reviewed for disinfection process, tank storage time period and maintenance strategies Project received conditional approval with monthly water testing requirements i.e. E.coli, turbidity, total organic carbons (TOC) and total petroleum hydrocarbons (TPH) Testing requirements featured TPH due to position of storage tank under a parking lot 6

7 Recent IDPH Approved Projects Rainwater reuse for drip irrigation (Tier 3) System featured a roof-capture system Storage tank Harvesting system s location held a sensitive population Initial plans featured harvested water used for spray irrigation After consultation with Department, project managers moved to use a municipal water supply for spray irrigation and harvested water for drip irrigation only IDPH approved project with conditions of monthly testing for E.coli Lack of human contact with harvested water created different testing and operating requirements Recent IDPH Approved Projects Roof harvesting system with subsurface irrigation system (Tier 3) Subsurface irrigation through use of drip rings Department approval with monthly testing for E.coli 7

8 Non Case-by-Case Conditions Final construction documents submitted to IDPH At anytime an approved system poses a risk to public health, such system will be taken out of service immediately and any remedial actions required by IDPH will be implemented No changes to the system shall be made without express consent of IDPH after new plan submittal IDPH, its agents, or assigns, may enter at any reasonable time to observe the operation of the system All systems shall be installed by licensed plumbers employed by an IDPH registered plumbing contractor 8
