On April 6, the president pledged to launch the project in the just-ended month of July.
"I have informed your governor that I want to come and launch this industrial park in July," Ruto told residents as he launched the upgrading of the 13-kilometre Njoro-Beeston-Nessuit road to bitumen standard.
According to details shared with the public by the Nakuru County Government, the Egerton Agro City Park and the KenGen Energy Park have been conceived as the county's future industrialisation hubs.
Once finished, these projects are expected to attract manufacturing investors and other business ventures that will create job opportunities for young people and enhance Nakuru's economy.
Affordable housing
But it's not all bleak in Nakuru County, as both the national and county governments have made progress in the affordable housing program.
Construction of homes at the Bondeni Affordable Housing Estate began in 2021 and is scheduled for unveiling by year-end.
A total of 605 houses have been built on an 8.5-acre plot in Kivumbini Ward, contributing to the joint target of 50,000 homes set by the national and county governments.
The housing initiative includes 45 one-bedroom homes, priced at Sh1.55 million each, 180 two-bedroom units at Sh3.25 million each, and 380 three-bedroom units at a cost of Sh4.3 million per unit.
"At least here, the national and county government have delivered their promise to the people of Nakuru. We are looking forward to the completion of the Itare Dam project," said Dan Murugu, a civil rights activist.
In Nyandarua County, Ruto's administration pledged to focus on three key areas: agriculture, water supply, and road improvement.
Over the past year, Ruto has visited the county six times to initiate different projects. His first visit was to inaugurate the Ol' Kalou potato cooling plant and its borehole.
This facility will allow farmers to store potatoes before they are brought to the market.
In Bomet County, hopes are high among residents and leaders as they look forward to development pledges by Ruto.
Top on the list is the Sh20 billion Bosto water project which is expected to start this year and improve access to the commodity in the county.
Bomet Water and Sanitation Company officials said only 20 per cent of residents have access to piped water, and the hope is that the water project will increase access to more than 75 per cent of the remaining population.
Konoin MP Brighton Yegon said they cannot wait for the commissioning of the project.
"Hopefully, the President will come and launch the Bosto water project this year. As we wait to have our homes to be connected to the water supply, our youth will be lucky to secure employment opportunities," said Mr Yegon.
Job creation
The MP estimates that thousands of jobs will be created during the project and after it is completed.
Mr Yegon challenged the youth to study water-related courses in college, saying they have a 'once-in-a-lifetime' opportunity.
But residents are running out of patience over delays to start the project. They cited broken promises by the previous government.
"I hope the President is not paying lip service. The project is late, and our need for water is so huge that it may not wait long," said Elias Tonui.
Mr Tonui said the number of pledges fulfilled by Ruto will determine the amount of support he can expect from the county in future.
Young people are also buzzing with expectations over a promise to set up a Sh100 million software hub.
The project, which has been proposed to be set up in Mulot, promises thousands of jobs to locals.
Former Bomet East MP Beatrice Kones says she is optimistic the project will help the youth tap their IT skills positively.
Ms Kones says that with many cybercrime cases being reported in Bomet, the youth must use their skills to build the country. "There are many jobless youth with skills that can be nurtured and put to good use."
Bomet East and Chepalungu sub-counties are also looking forward to improved roads spanning more than 100 kilometres.
Among the roads Ruto has pledged to tarmac are Merigi-Tegat-Kaporuso-Chemaner-Kembu-Longisa in Bomet East, and Sachora-Sigor-Kaboson-Chebunyo road in Chepalungu.
The two roads were left pending by the Jubilee administration, but Ruto has promised to revive them and ensure they are completed.
Bomet East MP Richard Yegon said the poor road networks in the region had meant residents could not easily access markets to sell their produce.
