and transmission lines under the supervision of the Dar es Salaam Water and Sewerage Authority (DAWASA) has impressed the Parliamentary Committee on Public Investments (PIC) that wished the work-spirit is sustained countrywide.
Members of the Parliamentary Oversight team entrusted with the duty to see whether public investments comply with the approved financial or business principles also underscored the need for additional efforts by water authorities to help reduce the ratio of non-revenue water (NRW).
During inspection of water projects in Dar es Salaam and Coast regions recently, the legislators under the chairmanship of Albert Ntabaliba Obama, (Buhigwe-CCM), pledged support on recovery of the balance due (debts) especially from large-scale water users.
The guided tour jointly organised by the management of DAWASA and the Dar es Salaam Water and Sewerage Corporation (DAWASCO) was also graced by the Treasury Registrar, Dr Oswald Mashindano who pledged support to water authorities on debt recovery efforts.
“But you need to submit relevant data (records) early enough to identify all defaulters before budget allocation. If necessary deductions will be made accordingly water bills must be cleared for sustainable good water service,” Mapigano insisted.
The lawmakers started the visit at Dawasco headquarters near Gerezani area where the Chief Executive Officer, Eng Cyprian Luhemeja and CEO of Dawasa, Eng Archard Mutalemwa informed the delegation about ongoing efforts to not only improve water services in Dar es Salaam but also increase the supply through expansion of various water sources including deep wells in Mpera and Kimbiji in Mkuranga District.
“The completed expansion work of Upper and Lower Ruvu Intake, coupled with installation of brand new powerful electric pumps increased the supply. Due to aged infrastructure of water distribution network the level of non-revenue water rose to 50.8 per cent by July 2016. However additional efforts lowered loss of water to 43.3 per cent,” Luhemeja explained during presentation.
According to him, until the end of last year (2016) Dawasco recorded unrecovered revenue amounting to 28.09 billion/- against its total assets value of 44.59 billion/-.
“The total of revenue collected from water services provided in the past six months (July – Dec 2016) amounted to 36.7 billion/-. The outflow during the specified time period was 33.13 billion/- leaving the company coffers with 3.57 billion/-,” the CEO explained.
The committee was informed about other short and long-term detailed rehabilitation plan to be jointly carried out by Dawasa and Dawasco. This includes construction of sewerage drainage system in Ilala, Mwananyamala, Kinondoni, Temeke and Mbezi Beach together with installation of modern water treatment Plants in Jangwani, Kurasini and Mbezi Beach.
The visit proceeded to Upper and Lower Ruvu Water Intake Plants, the river sites from which at least 80 per cent of water supplied in Dar es Salaam and some parts of Coast Region come from.
Ruvu River originates from distant sources in Morogoro Region. The exceedingly low water level below 16m which is just a meter above the acceptable limit caught the attention of the MPs who inquired about technical measure to rescue the situation.
The CEO of Dawasa, Eng Archard Mutalemwa informed the committee that until the recent past, Dar es Salaam required 450,000 cubic meter of water a day but only received 300,000 cubic metre a day which created a deficit of 150,000 cubic metres.
“That was the past. Much has been achieved through investment. Just the testing of newly installed three electric pumps with a total capacity to push 270,000 cubic meters a day at Lower Ruvu Intake increased the supply to 502,000 cubic metres even before official opening of the plant,” Mutalemwa explained.
The projections focused on increase of the supply from 300, 000 cubic meters to 710,000 cubic metres a day by 2016.
In order to realise the objectives, drilling of deep exploration boreholes in Kimbiji Aquifer in the outskirts of Dar es Salaam and improvement of water distribution network in areas that previously lacked the supply is underway.
Other projects accomplished include the 10 million litres water reservoir at Kibamba area in addition to construction of new transmission pipes from Upper and Lower Treatment Plants with expansion of both Kimara and Ardhi University reservoirs.
These are some of the projects that impressed the legislators who wanted water conservation awareness to be shared countrywide for protection of water sources and installed valuable machines.
At the moment water is produced from four main sources namely Lower Ruvu from the previous supply of 182,000 cubic meters per day to 270,000; Upper Ruvu from 82,000 to 196,000; Mtoni 9,000; and Boreholes 27,000 to make 502,000 per day. Some places in Dar es Salaam that previously never had the supply receive water at the moment.
Commenting on the effects of prolonged drought as witnessed at the main supply source of Ruvu River, the situation that threatened closure of pumps at the Intake Plants, the CEO said the long-term solution to the challenge was construction of Kidunda dam in Morogoro Region to sustain the water level.
“Designing of the dam began in 2010 ending in 2012. The design includes elevation of the river embankments at the selected suitable topography in Kidunda, Morogoro Region to allow collection of water to be released in dry season. From the dam at least 20MW will be connected to the national power grid,” Mutalemwa explained.
He said the Environmental and Social Impact Assessment (ESIA) had been carried out and completed in 2012 in compliance with the World Bank requirements, adding that Dawasa and Dawasco continued to work closely with Wami-Ruvu Basin’s to fight environmental degradation such as charcoal making, cultivation and other human activities near water sources.
The chairman of PIC, Albert Obama said water bill system should be improved to avoid wrong invoices issued to wrong people or skipping consumers.
Looking at two modern clarifiers near Mlandizi and Bagamoyo whereby muddy water is purified and treated accordingly, Zainabu Vulu (CCM) said the public should be informed about expenses involved in the entire water production and distribution process that also involved treatment to kill germs.
“There must be a regular awareness campaign on water conservation for the community to change bad attitude of careless use of water.
Water authorities must take the initiative to learn from others about measures taken to control such loss of water as non revenue water at the tune of 38 per cent is unacceptable and still too high to bear.
We (people living close to main pipes) need water in our neighbourhood for veritable application of the slogan “Tua ndoo kichwani as advocated by Dawasco,” Vulu insisted.
Constantine Kanyaso (Geita CCM) said the pronounced percentage of non revenue water should be quantified to know exactly how much the figures stand for in terms of revenue.
Members forming the PIC, with their constituencies in the brackets, are Esther Nicholas Matiko, (Tarime Urban- Chadema), Joseph Leonard Haule (Mikumi Chadema), Sabreena Hamza Sungura (Special Seats- Chadema), Edwin Sanda Mgante, (Kondoa Urban-CCM), Joseph George Kakunda, (Sikonge- CCM) and Fatma Hassan Toufiq (Special seats-CCM).
