STUDIES funded by the Asian Development Bank in 1987 identified Kaiduan as a suitable site for the construction of the proposed RM2.8 billion dam.
Infrastructure Development Minister, Datuk Seri Joseph Pairin Kitingan, said the study entitled "Second Sabah Water Supply Project" by the bank and the "Water Supply Resources Master Plan for Sabah" study in 1994 determined this.
However, while the mega project is still at a "site study" and "further investigation" phase, he said the company entrusted to carry out another feasibility study, WCT Berhad, must take into account all aspects, including its impact and effect on the social landscape, economy and the environment.
"My Ministry will also monitor the development of the study and ensure the negative effects would be minimised and that the project benefits the people, especially in Kota Kinabalu, Penampang, Tuaran, Putatan and Papar, in particular," he said when winding up for his Ministry, Thursday.
According to him, initial study by WCT showed the present water supply would not be able to sustain demand in Kota Kinabalu and its immediate districts after 2010.
It is for this reason, he said, that the dam is proposed at Kaiduan to ensure water supply is adequate for KK, Tuaran, Penampang, Putatan and Papar until 2050.
He said the proposed Kaiduan Dam in Papar would only involve an area of 5.2 square kilometres.
"The number of villages affected is also only four and not eleven as reported in the mass media," he said, adding that the number of houses to be affected is only 22 units while the number of villagers expected to be relocated are between 250 and 300.
And if the project is implemented, Pairin assured that the affected villagers would be compensated and given titled land the size of the land acquired by the Government.
The villagers concerned would also be provided houses and basic amenities such as water and electricity supply and road infrastructure.
He said the number of consumers expected to benefit from the Second Phase Kota Kinabalu Water Supply Project is 1.1 million when the first phase of the project is completed by 2016.
To this end, he said the people in Sabah should emulate the spirit of cooperation displayed by the people in Sarawak to its Government for the sake of development in the State.
The Bakun Dam, he said, involved a water catchment area of 14,750 square kilometres with the submerged area being 696 square kilometres and the affected villagers numbering about 10,000.
Pairin said each time they make plans to construct a plant or water supply system in an area, his Ministry would take into consideration not only how to sustain the present water supply but also how to ensure water supply in the future.
He said the "under-utilised" Segaliud Water Treatment Plant would be able to cater to the demand in Sandakan until 2020.
"If we only build the plant to accommodate the present need then certainly the problem of water supply shortage in Sandakan would recur (in the future) and cause the people there to suffer again," he said.
As for water supply problems in Sukau, he said the treatment plant would be completed in March next year.
He said the water treatment plant would have the capacity to provide treated water to about 2,000 houses in Sukau district.
He said the Ministry is very concerned with water needs in rural areas, hence the inclusion of water supply projects under the Rural Water Supply Programme (BALB) under the 10th Malaysia Plan (10MP).
The Tungku Water Treatment Plant, he said, has already been approved and would commence construction next year.
On severe water supply disruption at Jalan Abaka, Jalan Chester and Jalan Tanduk in Tawau, Pairin said the Water Department has identified the damage and was now in the process of repairing it.
"In the long term, the reticulation pipes in Bandar Tawau Lama would be replaced with new reticulation pipes," he said.
On Sri Tanjong Assemblyman Jimmy Wong's suggestion that the Government give the first 30 cubic metres of water free to consumers, he said the Selangor Government is able to do it because the water tariff for commercial and industrial consumers in Selangor is high.
He said due to this situation, the consumers there automatically would receive free "cross subsidised" water supply for the first 30 cubic metres.
"But the water tariff for domestic and commercial users in Sabah, they are charged a uniform rate of 90 sen per cubic metre," he said.
The tariff, he said, is much lower compared to the water tariff imposed in Selangor.
And if they were to give free water to the consumers, he said they would not be able to contribute to the State's revenue.
Pairin, nevertheless, said the water tariff in Sabah has not been reviewed since 1981.
"Maybe it is time that my Ministry review the water tariff because the cost of production and water supply has increased," he said.
On the issue of roads raised by the assemblymen, he said many of their requests would be listed under the 10MP.
On repairing bridges throughout Sabah, Pairin said a programme to strengthen the linking infrastructure is being implemented and expected to be completed in the 10MP.
He said of the RM386.22 million allocation to his Ministry for development expenditure, RM170.43 million would be allocated to the Public Works Department (PWD), RM172.37 million to the Water Department, RM19.09 million to the Sabah Railway Department and RM24.33 million to the Ports and Harbour Department.
Of the RM170.43 million allocated to the PWD, he said RM114.65 million would go towards road projects, RM21.34 million for bridge projects, RM28.35 million for sewerage projects and RM6.09 million for building projects.
He said his Ministry would be spending RM50 million to reduce non-revenue water (NRW) in Sabah.
It also would be spending RM1 million to build or upgrade water treatment plants, he said, adding that RM5.03 million is for pipe connection, RM3.85 million to upgrade the main, distribution and reticulation pipes, RM1.13 million to build, replace and upgrade water pumps, RM99.97 million to pay water concessionaires and RM11.59 million for emergency or unanticipated water supply programmes throughout the State.
