WCI are fully insured and carry professional indemnity insurance, contractors all risks and public, employers and products liability insurance.

All our staff are trained and qualified to the highest level for their roles.  Our Civil Engineers hold appropriate Engineering degrees; our Project Engineers are fully qualified surveyors and site managers and our Service Engineers are all in-house trained and British Water accredited

Our Customer Warranty for Installation Services (Workmanship warranty) document is available on demand. Manufacturer’s Product Warranties cover the products supplied by WCI (i.e. tanks, blowers, pumps etc).

We’re not affiliated to any one manufacturer so we will always choose the best system to address the individual needs of each customer and the site in question.

We are accredited installers and service providers for a number of systems, but we install, commission and service all makes and models of water and sewerage-related equipment including GRAF, Marsh, WSc (formerly WPL), Premiertech Aqua, Klargester, Tricel, Xylem and TT Pumps to name a few.

WCI are not emptiers, but we are happy to recommend one of our trusted partners.

The frequency of emptying depends on the type and size of the treatment plant and what it is serving. Small domestic plants are on average serviced and emptied once a year while commercial systems can be serviced and emptied every 3 months.

For example a plant installed to serve a 4 bedroom home where only 2 people are living may only need emptying every 3 years due to underloading of the plant.

Commercial plants range between every 2 months to every 6 months. When WCI services the system, we will take a sludge reading and test the discharge for the ammonia value which means we can advise when the plant needs emptying.

WCI will take care of all the calculations as part of the process. There are the various methodologies employed for the calculation of ‘Total Phosphorus’ (TP) including the Royal Haskoning method employed by many LPAs and the Ricardo method promoted by Natural England. WCI’s calculations will be approved by Somerset Council as part of the mitigation process.

WCI credits are always priced competitively according to your requirments. Speak with the No Nonsense Nutrient Neutrality team to discuss your project and how WCI can help.

With an upfront non-refundable deposit of only 10%, financial exposure from potential planning refusal is minimal with WCI’s scheme. The balance is typically due after planning approval.  For large outline planning applications, payments are deferred until closer to commencement.

Our British Water-Accredited Service Engineers are trained and qualified in the commissioning and maintenance of treatment plants.
We have the resources and balance sheet to deliver on our promises

Upgrades are only possible in areas affected by ‘Nutrient Neutrality’ restrictions. Unfortunately, these areas do not specifically match postcodes so the easiest way for us to determine whether your property lies in a suitable location is for us to check using our mapping system. Please register your interest and we’ll check for you. Please remember, you could qualify for a free upgrade if:

You own a property with an existing septic tank.
You’re located in an eligible scheme area.
You’re willing to sign an agreement to ensure the new system is kept in good working order.
Bear in mind that the sewage treatment plant requires a standard 230 V electrical supply. The electrical consumption is very low (less than a 60 watt lightbulb for a single house) so even the most ‘off-grid’ housing can generally be accommodated.

Shared systems can be upgraded. Both you and your neighbour will need to enter into shared legal agreements. Please talk to your neighbours and ensure they also want to upgrade before contacting us as we cannot negotiate with your neighbour on your behalf.

If you want to separate your system from your neighbour, WCI can provide a funded sewage treatment plant and separate you from your neighbours under the scheme. However, this implies a new discharge either to ground or to a stream which must be technically feasible. And we cannot separate your property from neighbours if it would ‘cut them off’ from the existing system. Please register your interest and we will consider the options when we survey your property.

Even if your tank lies on third party land, we can still upgrade but the new sewage treatment plant will need to be located on your land. The new sewage treatment plant can still discharge into soakaways or streams that are not on your land.

Most upgrades will take 3-5 days depending the particulars of your property.  Works can take longer if access is tricky, your garden is landscaped, we need to resurface driveways, and so on.
You will not have to move out whilst the upgrade takes place, there will naturally be some disruption – such as restricted use of your garden or needing to find alternative places to park your car – while the upgrade is completed but in almost every case, you will continue to have the use of your foul drains throughout the works. 

The installation of a new sewage treatment plant requires the use of excavators and dumpers.  This can be quite dramatic if you’re not used to groundworks.  However, we have over 40 years of experience of installations in domestic properties and we pride ourselves in our quality of reinstatement. Take a look at some of our past project to see examples of a WCI finish. 

For you to qualify for a free upgrade, you must enter into a ‘Planning Agreement’ with the Council. The agreement is called a ‘Unilateral Undertaking’. You will be agreeing to:

The installation of the new sewage treatment plant and the decommissioning of the old system
Appointing a competent service provider for the maintenance of the new sewage treatment plant for the life of the system.
Having the discharge from the sewage treatment plant monitored each year to ensure that it is performing the required level. We will do this free of charge for the first five years following installation.
Only ever replacing the new sewage treatment plant with a system which delivers an equivalent level of treatment quality.
Allowing the Council rights of access (on 21 days’ notice) to your property to check that the sewage treatment plant is working.
And not to sell the land where the sewage treatment plant lies independently of the property

Yes, we are supplying and installing the new sewage treatment plant free of charge but it will be yours on completion of the works.

If/when you come to sell your property, the Council will register your agreement to the conditions listed as a legal charge on the property and the obligations will be passed to any new owner of the property. In many ways, this may aid the sale of the property as you will be able to demonstrate that your foul drainage system is completely compliant

If you decide not to proceed with an upgrade of your sewage treatment plant with WCI, or indeed, if your property is not eligible for a free upgrade as part of this scheme, rest assured that your details will not be shared with anyone outside of WCI.

In line with our company privacy policy, we hold all personal data securely and will not pass details of your property or its sewage treatment plant onto any third party.
