Clark tanks are manufactured to be better than other poly tanks because...
1. The walls are much thicker at the base. That's where the pressure is and there are no vertical seams.
2. Made from durable, UV stable food grade polyethylene which has no fibres, rust, corrosion or taste tainting problems.
3. The attractive multiple curved rib profile has a quality finish to compliment quality homes.
There is a range of colours from which to choose including:
- Merino
- Beige
- Black
- Wheat
- Heritage Green
- Bronze Olive
- Grey
- Pale Terracotta
- Heritage Red
- White
- Rivergum
-
Mountain Blue
- As part of our quality control, Clark Tanks over 1100 gallons are ultrasounded to ensure correct thickness.
- Clark Tanks have a Hi-Ab available for ease of placement of tanks 5200 gallons and larger onto prepared sites. The Hi-Ab is available at customers request for tanks 5000 gallons or smaller.
Site preparation and maintenance for a
CLARK POLYETHYLENE TANK
1. Ensure the location of the tank is LEVEL, STABLE GROUND which has UNIFORM COMPACTION (free of soft spots). Do not locate a large watertank close to retaining walls or embankments without first consulting a professional engineer to ensure ground is capable of supporting the weight of the full tank.
2. Ensure the surface of the site is free fro sharp objects or stones and is compacted.
3. Spread a thin layer (approx. 20-40mm) of METAL DUST (3mm), bedding sand can be used but is prone to erosion; evenly over the level ground, at least 500mm greater than the diameter of the tank. Once it is compacted and level you may then place the tank directly on top of this material. To assist with reducing soil erosion, back fill to first rib.
4. Ensure the METAL DUST is contained under the tank at all times and cannot be washed away. This can be acheive by diverting all run off water away from the site and retaining the METAL DUST with some form of retaining structure e.g. (cement strip, rocks or sleepers etc.).
5. For strand applications, ensure the stand is designed to carry the weight of a full tank. Support slats on the stand should be no further than 20mm apart.
6. For concrete slab application the slab must be at least 6" bigger than the base diameter of the tank and at least 6" thick with 2 layers of SL82 mesh 75mm apart and a thickening of 8" wide and 8" deep with N16 reo bar at th bottom of the thickening around the edge of the slab and a 32 mpa concrete mix. If in doubt of soil stability, you must consult a civil engineer and they design the slab accordingly.
7. Ensure all plumbing from the outlet is well supported and cannot be knocked (A flexible coupling ensures no strain is applied to the outlet).
8. Ensure all overflows are plumbed away from the tank site to reduce the possibility of site erosion.
Your Clark Polyethylene tank requires very little maintenance, simply check the site for any erosion and clean leaves etc, from the roof, inlet and overflow screens at regular intervals.
