What is flushing point?

A flushing point is a capped pipe which is accessible on the surface for maintenance. Blockages can be cleaned or flushed out. They can be found at pipe junctions or where small-bore sewers are connected to a conventional sewerage.

How does subsoil drainage work?

A subsoil drain is a drainage system which is installed to expel excess water from the surrounding soil in buildings. The perforated or slotted pipes are placed underground and are usually covered by geotextile material to stop soil entering it.

Does subsoil need drainage?

The Benefits of subsoil drainage Protects foundations and your home: Subsoil drainage increases the stability of the footings of a building and reduces foundation movements due to soil moisture content. Prevents water pools: With water draining away, it doesn’t accumulate on the surface.

What is a low flashpoint?

Flash point is the lowest temperature at which a chemical can vaporize to form an ignitable mixture in air. A lower flash point indicates higher flammability. At the flash point, the vapor may cease to burn when the ignition source is removed.

What is subsoil drain?

Subsoil Drain. A Subsoil Drain is a slotted or perforated pipe laid below ground, and designed to remove excess water from the surrounding soil. Subsoil drains are often surrounded by a geotextile material to stop soil particles entering the pipe.

Why is subsoil drainage?

Subsoil drainage can improve the soil moisture relationship by keeping the ground water-table well beneath the paved surface. The principal object of all drainage is to facilitate the production of a subgrade of uniform bearing value and strength.

Can you put a bend in underground drainage?

Simply enough these are the changes of direction on a drainage system which are usually available from 11 ¼ to 90 degree in most materials, long and short radius bends are available and they can be plain ended as shown below left (clay) or single or double socket (underground plastic).

How deep should drainage pipes be buried?

Pipes laid at depths less than 600mm and which are not under a road should, where necessary, be protected against damage by placing over them a layer of concrete, paving slabs or similar. A minimum 75mm cushioning layer of granular material must be laid between pipes and the slabs or concrete.

What is a high flash point?

The flash point is an indication of how easy a chemical may burn if exposed to a temperature at or above the vapour’s auto ignition temperature. A Material with high flash point is less flammable or hazardous than a material with a low flash point.

What is a Class 2 flammable liquid?

Class II liquids are combustible liquids that have a flash point at or above 100 °F (37.8 °C) and below 140 °F (60 °C). Typical Class II liquids include liquids such as camphor oil, diesel fuel, pine tar, and Stoddard solvent.

Why is subsoil important?

Subsoil is an important storehouse of moisture, especially since it’s usually much thicker than the topsoil, and the moisture isn’t lost as easily by evaporation. The higher clay content of subsoils makes for higher water holding capacity, too.

What are the Five Pillars of a subsurface drainage system?

This Factsheet provides information to help complete the initial and ongoing inspection and maintenance of a subsurface drainage system. The five pillars of an effective subsurface drainage system are: quality material – including pipe, envelope/filter (if necessary), fittings, risers, etc.

How do you flush a farm drainage system?

In most cases, it usually only spreads out and levels the deposit. A water supply is needed to flush the drainage system. Consider using an irrigation system if one is available on the farm. If the water supply is limited, a catch basin, or hole at the upper end of the plugged section will serve as a water reservoir.

How often should a new subsurface drainage system be inspected?

However, it is important that a new subsurface drainage system be carefully inspected and maintained for the first two or three years. Any weak spots that have developed in the lateral and main drains and any backfilled areas that have settled can be remedied and filled in.
