Plastic pipe conferences announced for 2017
The Plastic Pipes Conference Association ( PPCA ) has announced dates and venues for its two spin-off conferences and exhibitions in South Africa and China for this year .
The first event will be held on 4 – 5 September 2017 at the Emperors Palace in Johannesburg , while the second event will be hosted in Hangzhou , China , on 26 – 27 October 2017 .
The PPCA is organising these events in close collaboration with the respective plastic pipe associations , namely the Southern African Plastic Pipe Manufacturers Association ( SAPPMA ) and the China Plastics Piping Association ( CPPA ).
In South Africa , the conference will be held in conjunction with PIPES XI , the annual plastic pipes event organised by SAPPMA . At least 10 papers will be included from the international Plastic Pipes Conference that was held in Berlin during 2016 . For this reason , the duration of PIPES XI has been extended to two days .
Zoran Davidovski , spokesperson for the events , forecasts large attendances . “ Our industry is in a constant process of innovative change as it finds new solutions for replacing ageing steel and concrete pipe systems . In the midst of these improvements , industry and government are faced with the need for new technical standards .”
For South Africa , full details of the programme , registration , the exhibition , and sponsorship opportunities will shortly be posted on their website , www . sappma . co . za u

World Water Day 2017 : wastewater
World Water Day is held annually on 22 March as a means of focusing attention on the importance of freshwater and advocating for the sustainable management of freshwater resources .
An international day to celebrate freshwater was recommended at the 1992 United Nations Conference on Environment and Development ( UNCED ). The United Nations General Assembly responded by designating 22 March 1993 as the first World Water Day .
Each year , World Water Day highlights a specific aspect of freshwater . In 2017 , the theme will be ‘ Wastewater ’ and in 2018 , ‘ Nature-based solutions for water ’.
Each year , Aqua for All organises , together with the Netherlands Water Partnership , the Dutch celebration of World Water Day .
World Health Organisation statement
Globally , the clear majority of all the wastewater from our homes , cities , industry , and agriculture flows back to nature without being treated or reused , thereby polluting drinking- , bathing- , and irrigation water and losing valuable nutrients and other recoverable materials .
Reducing , safely treating and reusing wastewater , for example in agriculture and aquaculture , protects workers , farmers , and consumers , and it promotes food security , health , and wellbeing .
What is wastewater ?
Wastewater is any water that has been adversely affected in quality by anthropogenic influence ( pollution ). Wastewater can originate from a combination of domestic , industrial , commercial or agricultural activities , surface run-off or stormwater , and from sewer inflow or infiltration .
Municipal wastewater ( also called sewage ) is usually conveyed in a combined sewer or sanitary sewer , and treated at a wastewater treatment plant . Treated wastewater is discharged into receiving water via an effluent pipe . Wastewater generated in areas without access to centralised sewer systems rely on on-site wastewater systems . These typically comprise a septic tank , drain field , and optionally , an on-site treatment unit . The management of wastewater belongs to the overarching term sanitation , just like the management of human excreta , solid waste , and stormwater ( drainage ).
Sewage is a type of wastewater that comprises domestic wastewater and is therefore contaminated with faeces or urine from toilets , but the term sewage is also used to mean any type of wastewater .
Sewerage is the physical infrastructure , including pipes , pumps , filters , screens , channels , and so on , used to convey sewage from its origin to the point of eventual treatment or disposal .
