Water bosses and former showjumper Harvey Smith are in financial deadlock over the value of land to be used for a sewage outfall.

Mr Smith, of High Eldwick, Bingley, has been offered ten times the market value for an area of land he owns in Riddlesden, where Yorkshire Water wants to construct the outfall.

The water company has offered him £3,000 for the land, plus another £3,500 for a section of the field, which will be used to lay a sewage pipe.

If the two fail to reach an agreement by next Friday, Yorkshire Water plans to use its statutory right to construct the system in the nearby garden of Richard and Carolyn Mozejko, of Bradford Road, Riddlesden.

The couple, who have two children, have pledged to fight any attempt to get on to their land. The system will take foul and surface sewage from a new 400-home development off Swine Lane, Riddlesden.

A banner outside their property proclaims -- "Yorkshire Water, our kids don't want to play in Barrett sewage".

A Yorkshire Water spokesman says: "We have written a letter to Harvey Smith's agent offering him ten times the amount the land is worth.

"We are waiting for him to get back with a suitable offer or we will go through the gardens. We are trying to compromise."

Mr Smith had been offered ten times the value for the area of the outfall, a sum for the pipeline and compensation for physical losses incurred, he added.

Mr Smith says he had not been informed of any deadline date.

"They have not been in touch with me at all. Nothing so far has been done about it. The last time they spoke to me was in September.

"My offer to use my land still stands. The land is there but Yorkshire Water is so evasive and arrogant. They think they can trample and run over anybody," he says.

An angry Mr Mozejko says: "I will do anything in my power to stop them because of the way they have behaved. I have thought of a million ways."

He says he was unaware of any deadline and sympathised with Mr Smith because he had been offered a "ludicrous" amount in compensation by Yorkshire Water.

"At first they offered not a single penny and they wanted to put half the length of the pipe and the outfall on our land. Eventually they talked about an amount of £300," he says.
