DEWATERING THE INSTALLATION SITE
Mention “dewatering” to contractors outside of the underground construction trade, and typically, they have no idea what you are talking about. Mention dewatering to anyone in the underground construction trade, and they’ll tell you that it is one of the most important aspects of the installation, as a well designed and installed dewatering system will allow them to complete their project in a safe manner and prevent disastrous unforseen expense due to flooding, running sand, distorted or cracked tanks, etc.
Groundwater exists at various depths below ground level, and in simple terms, dewatering is the lowering of the existing water table so that current work can be done below this depth, concrete backfills can 'cure' and tanks can be installed without any subsequent damage due to higher future water tables. If the water table is above the level of the base of the excavation, then de-watering the site is essential both during and after the installation until the concrete is fully cured.
It is essential that your installer excavates a Trial Hole to the depth of the installation in advance of the installation itself to determine the depths of both the current water table and the maximum winter water table. If the water table is higher than the base of the excavation and your installer has any concerns, specialist advice should be sought as to the design and specification of the site specific installation. If your installer decides to design the installation himself, then it is his full liability should things go wrong as a result.
The lowering of the groundwater table can be achieved by different types of dewatering systems and the type of installation is directly dependent upon the soil type and the soil’s permeability (ability to pass water through pore spaces).
Soils can range from:
- Highly permeable, such as coarse sands and gravel that will allow for the pumping of high volumes of groundwater
- Low permeability, such as silts with lower groundwater pumping ability
- Impermeable soils, such as clays
The type of system or systems installed will vary depending on the excavation depth, size and type or types of soil present at the site. When it comes to dewatering, one size does not fit all and many UK general builders do not have a clue about it.
It is essential that your groundworking crew know what to do BEFORE they meet groundwater problems that can ruin any sewage treatment system.
REGULATIONS
Always insist that the installer knows the regulations that apply to sewage plant installations:
- The BS 6297 2007 +A1 2008
- Section H2 of the Building Regulations and insist on SEEING their copy of both
You would be amazed how many installers have no idea that these regulations even exist.
Waste Tech has many years of experience of all types of sewage installations and we can help the customer in chosing the right wastewater system for the particular site. This involves a site survey, percolation tests, considering the quality of the discharge that is required, the visual and audible impact, the purchase price, and the installation and running costs. The customer can then choose a system with confidence.
After choosing the sewage system, the location is carefully marked out together with the drain runs. The customer is made fully conversant with the proposed system to make sure they are fully aware of all aspects of the job.
Prior to any work starting, we recommend taking photographs of the site. Also before work starts, flowers and shrubs should be dug up and kept for re-planting.
Once work has commenced, our we liaise with customers at all stages of the installation.
On completion, the site is reinstated to its previous condition, if required.

A sewage treatment plant can solve many sewage disposal problems when no mains sewer connection is available. We can survey your individual site and advise whether a septic tank or a wastewater treatment unit would be the most suitable. There are always many factors to consider and from our experience we normally find that several different schemes can be considered.
CORRECT SERVICE AND MAINTENANCE RECORDS FOR SEWAGE TREATMENT SYSTEMS ARE INSISTED UPON BY THE ENVIRONMENT AGENCY AND FORM A CONDITION ON THE DISCHARGE PERMIT.
Whatever sewage treatment system you install will require regluar servicing by a trained Sewage Treatment Plant Service Engineer, according to the manufacturers instructions. Systems which are not serviced regularly POLLUTE our streams and rivers and lead to prosecution by the Environment Agency. Please see the disaster photos on our sewage reports page
Full Sewage Installation service available, including gravelless soakaway systems as in the photo. Please ring for a quote.
ALWAYS insist on seeing the Service Engineers British Water Accreditation card.
NEVER ALLOW UNQUALIFIED PERSONS TO TAMPER WITH YOUR SEWAGE TREATMENT PLANT!
Services for sewage treatment systems start at £75.00 plus VAT depending on the type of unit.
