HPWJ is used to clear blockages and debris from drainage pipes using engine powered water pump to spray jets at pressures up to 3000psi.
When the blockage in your drain can not be cleared by conventional methods therefore HPWJ is the next viable solution.
In order to carry out drain clearing an access point is required. This is usually in the form of either manholes, large square or round panels in the ground, or an access point built or cut into the above ground pipework. Some properties do not have any of these and access may need to be created to carry out the drain clearance. This may require alterations to your drainage system and will be discussed with you after our preliminary investigation, before any works are carried out.
Sometimes your property will experience a blockage that is not within your property boundary. Under Water Regulations (2011) , once the drain goes beyond your property boundary, it is classified as a share drain and is covered by your local water authority. Our engineers will advise you on the best course of action if this occurs.
Some access points are not located within your property boundary, these could consist of above ground access points located on your neighbours properties or manholes located out in the street.
if access is required through the neighbouring properties to carry out work written permission will need to be granted before any works take place.
If the manhole access is located out on the street you would need to contact your local water authority as this is considered to be a shared drain. Our engineers will advise you on the best course of action.
Not all drains lead to the same sewers.
waste from your kitchen, bath, shower and wash basin (grey water) along with your toilet facilities (foul waste) should all lead to the foul waste drains loacted on your property and will run to either the local sewer located in the street or to a septic tank on your porperty.
Rainwater from the guttering on your property, ground water in you garden and driveway (storm water) should lead to either the local storm water drains. many properties do not have storm water drains and may run to either soakaways or into the water table (see what is a Soakaway).
A soakaway is any point where a stormwater drain runs directly into the earth and is absorbed by the water table. These can range from a simple hole in the ground to a system of perforated pipes to a Soakaway tanks located beneath your garden or driveway.
Over time build up of sediment and leaf matter will accumulate within the soakaway and connecting pipework. sadly these are difficult to maintain and cannot be adequately cleared using HPWJ.
