The first 25mm of rainfall from a newly installed roof should be discarded before drinking water collection starts, and always disconnect downpipes when painting a roof. Spouting should be regularly cleaned to avoid the build-up of dirt and debris that can affect water quality. We collected rain water straight from the roof and sent to the laboratory. It meets the Drinking Water Standards of NZ 2005 (revised 2008). The Drinking-Water Standards for New Zealand provide requirements for drinking-water safety. The Standard is available on the Ministry of Health website at this [link](http://www.health.govt.nz/publication/drinking-water-standards-new-zealand-2005-revised-2008).  ![water_test01.jpg](https://blog.rossroofgroup.com/hs-fs/hubfs/water_test01.jpg?width=700&name=water_test01.jpg "water_test01.jpg") ![water_test02.jpg](https://blog.rossroofgroup.com/hs-fs/hubfs/water_test02.jpg?width=700&name=water_test02.jpg "water_test02.jpg") ![water_test03.jpg](https://blog.rossroofgroup.com/hs-fs/hubfs/water_test03.jpg?width=700&name=water_test03.jpg "water_test03.jpg") ![water_test04.jpg](https://blog.rossroofgroup.com/hs-fs/hubfs/water_test04.jpg?width=700&name=water_test04.jpg "water_test04.jpg") - [Tweet](https://twitter.com/share) [« prev](https://blog.rossroofgroup.com/tilcor/dachholz-international-2016) [next »](https://blog.rossroofgroup.com/tilcor/tilcor-shingle-withstands-severe-wind-farm) ### Recent Posts ### POSTS BY TOPIC - [December 2016 (14)](https://blog.rossroofgroup.com/tilcor/archive/2016/12) - [November 2017 (3)](https://blog.rossroofgroup.com/tilcor/archive/2017/11) - [May 2017 (2)](https://blog.rossroofgroup.com/tilcor/archive/2017/05) - [June 2017 (2)](https://blog.rossroofgroup.com/tilcor/archive/2017/06) - [July 2017 (2)](https://blog.rossroofgroup.com/tilcor/archive/2017/07) - [October 2018 (2)](https://blog.rossroofgroup.com/tilcor/archive/2018/10) - [February 2017 (1)](https://blog.rossroofgroup.com/tilcor/archive/2017/02) - [March 2017 (1)](https://blog.rossroofgroup.com/tilcor/archive/2017/03) - [April 2017 (1)](https://blog.rossroofgroup.com/tilcor/archive/2017/04) - [October 2017 (1)](https://blog.rossroofgroup.com/tilcor/archive/2017/10) - [December 2017 (1)](https://blog.rossroofgroup.com/tilcor/archive/2017/12) - [March 2018 (1)](https://blog.rossroofgroup.com/tilcor/archive/2018/03) - [April 2018 (1)](https://blog.rossroofgroup.com/tilcor/archive/2018/04) - [July 2018 (1)](https://blog.rossroofgroup.com/tilcor/archive/2018/07) see all ![](https://blog.rossroofgroup.com/hs-fs/hubfs/CTA.png?width=400&height=237&name=CTA.png "CTA.png") ![](https://blog.rossroofgroup.com/hs-fs/hubfs/CTA.png?width=400&height=237&name=CTA.png "CTA.png") ### Subscribe to Email Updates [Tilcor International Privacy Policy](https://content.rossroofgroup.com/privacy-policy-tilcor) [![Ross Roof Group](https://blog.rossroofgroup.com/hubfs/RossRoofingGroup_Jul2016/Layout/RRG-logo.jpg "Ross Roof Group")](http://www.rossroofgroup.com/) ![Fast Deloitte 50](https://blog.rossroofgroup.com/hubfs/RossRoofingGroup_Jul2016/Layout/NZ_Made-logo.png "Fast Deloitte 50") [![MRM](https://blog.rossroofgroup.com/hubfs/RossRoofingGroup_Jul2016/Layout/mrm-logo.jpg "MRM")](http://metalroofing.org.nz/) [![roofing-association](https://blog.rossroofgroup.com/hubfs/RossRoofingGroup_Jul2016/Layout/roofing-association-logo.jpg "roofing-association")](http://www.roofingassn.org.nz/) [![nz-steel](https://blog.rossroofgroup.com/hubfs/RossRoofingGroup_Jul2016/Layout/nz-steel-logo.jpg "nz-steel")](http://www.nzsteel.co.nz/) ### like what you see? get a quote!
