Unexpected challenges have set back the raising of the Hazelmere Dam wall by six months, the department of water and sanitation (DWS) reported.
Initially scheduled for completion in June 2017, the end date has been pushed out to December.
“There have been problems with rock anchors as well as the grouting,” said the department’s Mahaye Mbalenhle.
The raising of the Hazelmere Dam wall is part of an intervention developed by the DWS after it commissioned a feasibility study which indicated the current yield’s insufficiency to meet the growing demands of supply in the North Coast region.
The project to raise the Hazelmere Dam wall includes the installation of gates on the dam’s spillway and the stabilisation of the wall.
The dam will be increased by seven metres to raise capacity from about 17.7 million m3 to 37 million m3 .
This will increase capacity by approximately 109% (more than double the previous capacity).
So the dam is not too big anymore?
Durban - KwaZulu-Natal dams have recorded remarkable recoveries in water levels as a result of steady rainfall around the province.
But, while the week’s rainfall has offered some relief - and even helped to lift water restrictions on those supplied by the Hazelmere Dam - those in drought-stricken areas are not out of the woods.
Authorities said while some dams recorded dramatic increases, the amount of rainfall remained below average.
Corporate stakeholder manager at Umgeni Water, Shami Hari-chunder, said the situation in the Hazelmere system had returned to normal after a two-year drought and stringent water restrictions.
The dam levels stood at around 40% in May.
“Following good rains from July to the present, the dam has risen to 70%, as at yesterday. All water restrictions in the supply area of Hazelmere Water Treatment Plant have been lifted. The areas affected are Verulam, Waterloo, Ballito, Umhlali, parts of Ndwedwe, Sea Tides and La Mercy.”
But he cautioned that much of the torrential rains had occurred in areas outside catchment areas.
Water restrictions and very minimal amount of outflow into the rivers.
After Saturdays storm, I was expecting a significant jump in some of the dams but, see for yourselves.
The severe ongoing drought has forced the Umhlathuze local municipality to implement a 90 percent water restriction.
The restriction came into effect yesterday.
Municipal spokesperson, Mdu Ncalane, says the current shallow level of the city's major dam at 19% - has left them no choice but to tighten the supply of water.
Durban – If KwaZulu-Natal doesn’t get above average rainfall in the next three months, the bid to bring our water supply back to normal will suffer a setback.
“For our dams to begin rising significantly, at least two seasons of above-average rainfall are required,” said Umgeni Water spokesman Shami Harichunder on Friday.
He said the next three months of the rainy season were crucial. He said that if above-average rainfall was not received, the water available in the Umgeni system would have to last until the next rainy season.
On Friday Midmar Dam was just over half full at 55 percent, its level having been raised with the help of an inflow from Spring Grove Dam.
Downstream, Umgeni Water’s other large dam stood at a miserable 27 percent.
“Water is normally transferred into Albert Falls from Midmar, but this has stopped because of inadequate water in Midmar,” Harichunder said.
“Midmar and Albert Falls dams will have to reach levels of 70 percent each to meet demand.”
This time last year Midmar stood at 48 percent and Albert Falls was at 40 percent.
Durban – Large parts of eThekwini Municipality will again endure water cut-offs, after a brief reprieve over the festive season.
And it doesn’t end there – longer shut off hours, possibly from 7pm to 6am – are on the cards as residents are failing to conserve the 15% use as mandated by national government.
eThekwini Municipality said yesterday restrictions that had been lifted over the festive season because of the influx of tourists, had now been reintroduced as the level of Albert Falls Dam, near Pietermaritzburg, had dropped to 26.1%. Midmar Dam, near Howick, is around 58%.
Several reservoirs in the region had run dry and if residents did not heed warnings to use water sparingly, bigger cuts would be enforced.
Umgeni Water also laid bare the dire situation facing the province, with poor rains failing to fill up dams. It held a media briefing this week to spread the message that the effect of the drought was severe, and stricter measures to conserve water were needed, along with infrastructure development.
Durban residents frustrated at water shut-offs would have to wait at least a few more months before they could see the end of dry taps, but it would take several years of good rains for dams to fully recover.
Umgeni Water spokesman, Shami Harichunder, said the drought still had a grip on the province, and dam levels were low.
“Our concern is that Albert Falls Dam is at 25% capacity. This dam feeds three municipalities, including eThekwini. These levels are very low and we need heavy rains. There isn’t sufficient water to meet the demand, and this is why we have water shut-offs. Midmar Dam, when full, overflows into Albert Falls.
“However, Midmar Dam itself is at 60%, and that level is also pumped from Spring Grove Dam, so essentially there is not enough water. For Albert Falls dam to reach capacity and put us in a better situation, we project that there needs to be three to four seasons of heavy rains,” said Harichunder.
This translates to three to four years of good rainfall.
Harichunder said that at the very least, water restrictions would be around for several more months.
Resources
“There will be no easing up until we get good rains over the catchment areas and the dams fill up. We need people to continue water conservation measures. We are sitting in a situation of inadequate water resources as a result of the drought and this affects us all,” he said.
Way way too little still...
BUT, there is a tropical depression in the Mozambique Channel at the moment which is predicted to intensify to a Tropical Cyclone and continue a south-west course. It could at the very least give some good rains to the Kruger and Northern KZN...
Can but hope that if it does go that far it doesn't turn into another Domoina.
