Stormwa­ter drainage re­pairs to min­imise flash flood­ing in Joburg

The Star Early Edition - - METRO WATCH -

AS PART of the City of Joburg’s on­go­ing ef­forts to ad­dress in­fra­struc­ture back­logs – in this case through the re­pair and re­ha­bil­i­ta­tion of the stormwa­ter drainage sys­tem – Robin­son canal, one of the city’s old­est canals, has un­der­gone an R8 mil­lion up­grade.

This re­pair will min­imise the in­ci­dence of flood­ing in the city. Due to cli­mate change, the city has seen an in­crease in flash flood­ing fol­low­ing spo­radic tor­ren­tial down­pours since 2009. This has re­sulted in in­creased water vol­umes which have neg­a­tively im­pacted on the age­ing stormwa­ter in­fra­struc­ture.

The Robin­son canal pro­ject has been di­vided into three phases. Phase 1, now 65% com­plete, is ex­pected to be com­pleted by the end of the month, said Nonhlanhla Makhubu, of the may­oral com­mit­tee for trans­port.

Phase 1 fo­cuses on re­pairs and re­ha­bil­i­ta­tion of an open chan­nel which ser­vices the in­ner-city from Main Street pass­ing through Selby and Ophir­ton and ends on Lake Street. Re­pairs have been un­der­taken on the canal lin­ings and sink­holes

Phase 2, sched­uled for the 2017/18 fi­nan­cial year with a bud­get of about R5m, will fo­cus on a six-month re­pair of the un­der­ground chan­nel, which re­quires in­creased safety pre­cau­tions be­cause of the trapped gases from the waste water in the lower-ly­ing struc­ture.

The Johannesburg Roads Agency (JRA) is in the process of ap­point­ing con­trac­tors for this phase.

As part of the city’s quest to stim­u­late eco­nomic growth and de­crease lev­els of unem­ploy­ment, 40 lo­cal peo­ple were em­ployed for the pro­ject. Four emerg­ing lo­cal sub-con­trac­tors are be­ing used, with the main con­trac­tor fe­ma­le­owned.

As we cel­e­brate En­vi­ron­ment Month, it is im­por­tant to un­der­stand the im­pact of waste­water and green­house gases on the en­vi­ron­ment. The im­por­tance of sys­temic adap­ta­tion to cli­mate change must be em­pha­sised in en­sur­ing the pre­pared­ness of the city’s in­fra­struc­ture to­wards safe, re­silient and sus­tain­able hu­man set­tle­ments, she said.

The City of Joburg’s five pil­lars un­der­pin­ning this ad­min­is­tra­tion’s strate­gic vi­sion align to the UN’s 17 sus­tain­able devel­op­ment goals.

“As a city, we are im­ple­ment­ing mit­i­ga­tion mea­sures in our in­fra­struc­ture projects to com­bat cli­mate change and its im­pacts. The struc­tural re­ha­bil­i­ta­tion of Robin­son canal en­sures sus­tain­able man­age­ment of stormwa­ter with risk mit­i­ga­tion mea­sures in place to re­duce im­pact and harm to bio­di­ver­sity and the sur­round­ing com­mu­nity.

“I would there­fore like to thank the res­i­dents of Joburg for their pa­tience while we ad­dress the cur­rent prob­lems of stormwa­ter drains re­sult­ing to flood­ing. We are com­mit­ted on build­ing and pre­serv­ing our stormwa­ter in­fra­struc­ture and en­sur­ing sus­tain­able in­dus­tri­al­i­sa­tion.

“Fur­ther­more, we en­cour­age our res­i­dents to con­tinue to re­port any road, traf­fic light, or in­fra­struc­ture faults on the JRA’s Find & Fix app.”
