Septic Tank Repairs

As well as servicing waste water systems we carry out all repairs from troubleshooting, blockages, air blower and pump replacement to full upgrades and rebuilds.

Septic Tank Cleaning / Emptying

If your septic tank needs emptying we can organise a sucker truck for you. For older gravity septic systems we can bring a digger and remove the lids and clean out the tank and reinstate the ground.

Just becuase you have a blockage or other issues with your tank it doesn't necessarily mean it needs emptying. We recommend not to empty your tank in most cases as you loose all the good bacteria which stops the tank working as it should.

As Warren Buffet says "Dont ask a barber if you need a haircut as you always know what their response will be" same applies when you call a Sucker Truck company to work on your septic system. They will always say it needs emptying then start solving the actual cause.

Pump Chambers / Pressure Sewers

Pump chamber repairs and servicing. We can service or unblock your pump chamber. We also carry out Macerator pump, Grinder pump, Vortex pump repairs and replacement.

Drip Line Installation Experts

Landwork specialise in installing drip irrigation fields for both commercial and private customers.

Our machines are specifically designed and built or modified in house and we feel our equipment is the best in New Zealand. We use vibrating mole ploughs to avoid stretching the dripper line like competitors trying to install it with static ploughs. Also our vibrating plows cause a minimum of damage to existing lawns and pastures.

The majority of our work is for septic system manufactures and drain layers who install aerated septic systems. 

Drianlayers often prefer to have us come in and plow the lines in and they do the connections or we can do the complete job.

We also offer all our services to the general public.

If your dispersal field is blocked up we can repair or replace the field. This often is the case on fields older than 10 years.

Often we can retrofit an existing dripper field with more flush taps and add more lines to keep it functioning for a few more years before replacement.

Subsurface Drip Line Irrigation

We are experts in sub surface drip irrigation.

With our skid steer and vibrating mole plough we can lay dripper line on most terrain with minimum disturbance of the ground.

If you need a raised mound we can supply the topsoil and shape the mound.

Ground Laid Drip Line Irrigation

We can ground lay drip line in gardens or steep or vegetated sites where machine access is not available or safe or where this has been specified in the design. We can truck in mulch and cover the lines or the customer can do this if they prefer

Raised Mound

If you live in a wet area or somewhere with a high water table then you will be required to put your dispersal field in a raised mound. We can supply the material (usually topsoil) and form this into a bun and plow the lines in the mound for you.

​Sand Trench

If you have a septic system that is not a treatment system then your dispersal field will usually be a sand trench. We can install these for new build or upgrades. Overtime these clog up from sediment and roots growing in to the holes. We have a few options to clear these out so you can get a few more years life from them.

​Soak Hole

If you have a really old septic tank then it probably discharges into a soak hole or seepage pit. These can block up over time and its getting harder and harder to drill another hole to use. If a new hole is required we can liaise with the local authorities to see if they will allow us to repair it this way or if not we can look at modifying your system to meet current discharge regulations.This can often be as simple as adding a pump and a sand trench to your existing tank or adding an extra pump chamber and sand trench.
