In 1918 the Sunday school is still showing on the map under the area name of Vardre close to Mount Pleasant and Graig Felin was known as Aber-Clydach.

The top of Clydach near Lone Road and Bryn Mair was named Upper Forge not yet having its slang title of 'Sunny Bank' with the locals.

This decline in revenue and profits was largely due to the competition from its rival the Swansea Vale Railway.

The population has recovered from the reduction seen in the early 1980s following the demise of mining and the heavy metal industries.

The centre of Clydach High Street, the main commercial area of the town has had major investments in improving its facilities.

These include reshaping and resurfacing of the road, new flagstones to replace tarmac pavements, new trees, new seats and cycle racks.

Today, with improvements in processing and a rationalisation of products, the refinery now employs just over 240 people, equating to 3% of the village's population.

The refinery is, however, a top-tier Control of Major Accident Hazard Regulations (COMAH) site,[5] due to the inherent nature of its process.

There are a number of churches and chapels in Clydach, serving both English and Welsh language speakers.

The Reverend Valentine Evans, who wrote the History of Clydach at the beginning of the 20th century, is buried in its cemetery.

A Kingdom Hall of Jehovah's Witnesses located on Capel Road is one of the oldest in Wales.

Originally a nine-hole course (dating back to the 1960s) that was intended to be a resource exclusively for INCO (Clydach Refinery) employees, the course now welcomes golfers of all ages and abilities throughout the year.

It provides a range of facilities including a community café, a full day care nursery (Forge Fach Day Nursery), a multi-purpose hall, ICT suite, training & conferencing facilities plus an external multi-use games area.

In 2011 the City & County of Swansea opened the 'Waterfall View' day service at Forge Fach.

In 2013, Cwmni Clydach Development Trust went into administration, leaving the future of Forge Fach uncertain.

[7] A local campaign group called for Forge Fach to be turned into a health, leisure, wellbeing and swimming centre.

The Cwm Clydach RSPB Reserve is situated on the outskirts of the village, en route to Craig Cefn Parc near the New Inn pub.

The Cwm Clydach nature reserve used to be the home to the Nixon and Bell Drift mine.

Little remains of the colliery now, and there is a walk up the valley past other remnants of other NCB and private mines.

Major work has recently been undertaken on part of the cycle route between Clydach and Glais.

The lottery-funded Sustrans laid a new tarmac path for pedestrians and cyclists, which begins alongside the River Tawe, behind the Vardre Rugby Club, and ends at Station Road in Glais.
