Lagos State Governor Babatunde Fashola says the present administration has planned steady water supply for the state residents till 2020.
A statement on Wednesday said the governor spoke during an inspection visit to the ongoing expansion of Adiyan Waterworks.
The waterworks would deliver 70 million gallons of water per day when completed.
Fashola, after the inspection, said the water projects which the administration was implementing would take the state to the level of sustainable and efficient water supply.
He said, "Currently, there are reticulation contracts that have been issued including pipe networks and pipelines being laid across the state to receive the supply of water when it is done.
"The planned expansion work at Adiyan, which has been on the drawing board since the 1970s, is expected to give the state 70 million gallons of water per day which is the combined capacity of all the mini water works and micro water works."
He added that the Adiyan expansion would help the government to serve areas like Iju, Agege, Mushin and Ilupeju.
Fashola said, "It will help us relieve pressure from Iju Waterworks and Adiyan Phase One by implementing the expansion which they planned almost three decades ago and bring water to people in those areas that I have mentioned.
"It will also increase our capacity therefore to sustain life, prevent disease, provide healthy living at affordable cost, reduce the dependency that our people currently have in purchasing water, some of which is of questionable integrity."
The governor said efforts were on to tackle lack of potable water in some areas in the state.
He said the government was also working on Odomola to serve Epe area.
Fashola was accompanied on the inspection by the Managing Director of the state's water corporation, Mr. Shayo Holloway; Commissioner for Works and Infrastructure, Dr. Obafemi Hamzat, and his Physical Planning and Urban Development counterpart, Mr. Olutoyin Ayinde.
