The final stage of a project to improve the sewage system at Uppark House and Garden in South Harting, West Sussex, is due to begin on 5 August.The work linking the National Trust place to the mains system at South Harting will require separate closures of two short sections of road between Uppark and the village on either side of the junction between the B2146 and B2141.

The work will take place for around three weeks in August and six to seven weeks in September and October, with the following road sections closed:

· Phase 1: B2146/B2141 junction to South Harting: 5 August to 23–27 August 2024

A period of flexibility has been built into the end of each phase of work to account for any unavoidable delays.

Gordon Gardner, General Manager at Uppark House and Garden, said: “This work will connect Uppark to the mains in a sustainable way that will avoid unnecessary disturbance within the South Downs National Park. It will also bring the system in line with Environment Agency regulations.

“We’ve deliberately scheduled the work in two phases to avoid disruption at the start of the new school year and during the two festivals at Goodwood.

“We realise the road closures will cause some inconvenience but we’ve worked with West Sussex County Council and our contractors to make sure the work will be completed as quickly and safely as possible.

“In the meantime, we’re very grateful for people’s understanding as we carry out the work.”

Road signs notifying motorists of the first phase of the work will go up on 15 July, with road closures and diversions in place from 5 August.

During Phase 1 of the work, traffic to South Harting from south of the closure will be diverted south along the B2141 towards Chichester then north on the A286 before following stretches of the A272 (Petersfield Road), B2199 and B2146 to South Harting.

During Phase 2, traffic south of Uppark House and Garden travelling to South Harting will be diverted south along the B1241 towards Chichester then north along the B1246.

Traffic from South Harting will be diverted along the B1241 to Chichester where those travelling towards Compton can then head north on the B1246.

The project requires road closures rather than temporary traffic lights because some sections of road do not have the minimum width required to safely accommodate a traffic lights system.

Although the road closure during the second phase of the work will cross the South Downs Way walking trail, the trail will remain open and walkers will continue to have access.

The work at Uppark marks the first time the 17th-century house has been connected to the mains sewage system. The new system has been designed to empty into the mains at South Harting during off-peak hours only.

Uppark House and Garden is currently closed to visitors while this work and a number of other essential renovations are carried out. It is due to reopen in summer 2025.
