Customer Testimonials

JW Clark installed a new septic tank in Overstone Park. This required careful handling as all the equipment had to be taken round Overstone Park Golf Course and all the work was adjacent to the Golf Course.The work was done efficiently and completed to our satisfaction, without receiving any complaint from the Golfers. They also did some work that was in addition to the contract without charge.

Naseby Treatment Plant

Key Tasks:

  • Dig out and install 16 person treatment plant
  • Set in concrete and surround with 10mm gravel
  • Lay new sewerage pipes from house to new tank
  • Lay pipe from tank to existing manhole 
  • Fill in old tank with spoil already on site
  • Backfill and reinstate as found, leaving no mess

A recent customer from Naseby was having problems with his sewerage treatment plant and it needed replacing. After being awarded the job, we got in touch with our friends at Marsh Industries, who specialise in tanks of all shapes and sizes. We ordered a 16 person treatment plant to replace the old one, and a dug a pit  with enough room around the edges to set the tank in `Gen 3` concrete. We laid a 4 inch drainage pipe from the house to the tank, where the sewerage can be broken into two parts, leaving eventual wastewater to run out through an outlet and into an existing manhole at the bottom of the garden, some 30 metres away.  We managed to dispose of the original tank and lose some spoil in the hole, saving our customer some money. We then reinstated to leave the grass as green as when it started!

Here is what the customer said:

It took me months of evaluation to decide how to replace my failed sewage plant, I found JW Clark LTD as a highly recommended installer through the equipment Manufacturer.

They gave me very clear Information on the timing of the project and all the time during installation our needs for minimal disruption were considered, the job was completed in a timely manner with consideration and least area damage on our soft ground, which after a month is nearly back to normal grassland. Although not the cheapest Supplier they offered very fair Value , and we are completely satisfied and also confident if any problems arise they'll be dealt with efficiently.
