HTI has helped to define the market for precast concrete tanks and construction methods. Over twenty years of experience have gone into our design for sewage holding tanks, and it shows in the quality of the product and in our roster of clients. Every new wastewater treatment plant, industrial wastewater system, or agricultural waste facility represents another potential customer for HTI precast concrete sewage holding tanks.
HTI sewage holding tanks are trusted by wastewater systems engineers and operators who depend on the strength and durability of their tanks and components on an every day round-the-clock basis. With HTI, you have a company that can custom design a sewage holding tank or other system according to size and flow specifications that will perfectly match your needs. We do tanks - and we do them right the first time.

Tank Design Sewage.
HTI's precast sewage holding tanks are known for their dependability and long life. The tank design includes strategically-placed seams which are filled with an industry-approved sealant provided by a member of the Chevron Family of Companies. This sealant and the tank itself is 100% environmentally friendly and environmental regulatory agencies have deemed it entirely appropriate to use HTI's tanks for potable (drinking) water storage.
HTI helps their clients get the right sewage holding tank storage system by offering one of the broadest arrays of custom specifications in the industry. We understand that whether you need a small sewage holding tank as part of a wastewater treatment system, or whether you require a water tank upwards from 300,000 gallons, you want professional, experienced help, and the highest quality product you can get.
Please take the time to view the rest of our site, and then contact us. Let HTI help you get your project - including sewage holding tanks - up and running smoothly.

05.31 Water supply structures : general information.
Present drinking water structures in the project area. This project will be decentralised. About (number) large diameter wells and (number) large diameter boreholes will be dug using local labour, construction methods and materials supplied under the local LETS systems.
About 6-9 solar submersible horizontal axis piston pumps or equivalent technology will be installed in each well. Each of the pumps will supply water to a dedicated water tank serving a local community. The well is the hub of the supply system. The water pipelines radiating from it are its spokes.
Schools will each receive one dedicated tank. Clinics, for further safety, will be served by two tanks each with its own pump.
Each well will be equipped with back-up hand-pumps (see Schedule 5 for a complete description of the hand-pumps).The hand-pumps will provide water during unusually long periods of bad weather.
Where culturally appropriate, there will be a communal washing area near each well so that women used to doing their washing in groups can continue to do so. The backup hand-pumps may also be used to service the washing areas and in cases of emergency.
The water supply is based on a water consumption of 25 litres per person per day. Since solar energy is to be used to pump the water, bad weather must be taken into account. For that reason, the tanks need to have a capacity for three days' use. Each tank will supply about 200 people. The capacity required to give 25 litres per day to 200 people for three days is 15m3, the planned size of the tanks.
05.31 Structures for the drinking water distribution system.
For possible technical solutions for the drinking water distribution system refer to:
DRAWING OF WATER SYSTEM STRUCTURES.
DRAWING OF TYPICAL WATER TANK AREA.
Usually just one Moraisian workshop will be held in a given project area.
Indicative participation
The Moraisian trainers
The project coordinator
Consultant Terry Manning
Consultant EOS advises
At least one representative of the ONG
Representative of the Health Ministry
Representative of the Rural Development ministry
At least 5 observers (possible coordinators for future projects)
30 persons indicated by the tank commissions interested in the systematic maintenance of the structures
100 persons indicated by the tank commissions, interested in drilling boreholes, drilling wells and building the associated civil and associated works
Duration of the workshop: about four weeks.
The Workshop will be expected to produce the following structures:
a) A coordination structure
- definition of the social form
- statutes
- rules
- professional and administrative structures
- financial aspects including payments
- relations with the local money LETS systems
b) Analysis of requirements

Drinking water structures.
The distributed drinking water supply structures are the structures which need the largest formal money capital investments. They will defined by the people themselves during a capacitation workshop following the formation of most of the other structures planned. The following general indications are therefore subject to changes, some of them important, from one project application to another. The following information should, however, give a fair idea of the size and nature of project applications.
