Above ground drainage performance specification

Above ground drainage performance specification

On traditional mass housing construction projects in the UK the above ground drainage can be a simple affair and is often undertaken by the contractor's mechanical subcontractor directly. The situation is completely different on one off bespoke new houses or refurbishments. Most houses we work on are grade 1 or 2 listed and changes to the fabric to enable new drainage facilities for clients need to be carefully coordinated. We recommend that an above ground performance specification is produced for all projects, as it is critical to...

Build over agreements and building over sewers

Build over agreements and building over sewers

If you wish to build over a sewer, you need a build over agreement. This is needed if you are planning to construct a building, an extension, underpinning or undertaking similar construction work near to, or directly over an existing sewer. The distance away from the sewer applicable depends on several factors, including the depth of the sewer, how critical the sewer is etc, although it is typically 3m. As sewers are frequently located running along the front and back of a houses, they are usually needed for...

Rainwater harvesting independent advice

Rainwater harvesting independent advice

Rainwater has been harvested – or collected, stored and then used when needed for hundreds, if not thousands of years. Rainwater harvesting remains a standard technique in many parts of the world without mains water, or accessible groundwater. Most areas of the UK have mains clean water supplies. Increasing demand is however been put on this limited mains system and there is greater consideration of the value of making developments more sustainable. All mains water is treated to a high drinking water standard, yet the vast majority...

Soakaway Design and Construction Advice

Soakaway Design and Construction Advice

A soakaway is a bespoke designed system to discharge water into the ground. Practically every new development from the smallest house extension to multimillion pound developments now have soakaway systems in the UK. In the past, especially on small developments, not much thought was given to the design of soakaways. It is perhaps because getting water into the ground appears like a natural process and therefore "should be easy". However, a building or road development – often located in an urban...

Section 101a or First Time Sewerage

Section 101a or First Time Sewerage

Section 101a is a mechanism for the public to obtain a public sewerage system. The informal name used by Engineers in the UK for such applications is first time sewerage. Therefore this is settlements which are requesting public sewerage, as they do not current have any public provision. Many rural developments have drainage which evolved over hundreds of years. Most systems are based on septic tanks, or mini package treatment works discharging to groundwater. Ground permeability can vary considerably even within the same village. The...
